<li>Did lvl 1 DIG LIG for PDF luc+ Nost, PR2 luc+ Nost and GST luc+ nost </li>
 +
<li>Performed a transformation of e.coli with LUC+ to increase luc+ plasmid quantity </li>
 +
<li>Grew agrobacterium up in broth with Rif and Kan. Agrobacterium consisted of colonies with lvl1 plasmids for GST TSHH nosT, PDF TSHH nosT and PR TSHH nosT. </li>
 +
<li>Picked the WRKY level 0 colonies and grew in broth overnight at 37 degrees. </li>
 +
<li>Performed PCR diagnostic on Luc+ samples with Luc+ specific primers and another set with TSH specific primers - Bands present with both, so samples are contaminated and cannot be used. </li>

Revision as of 21:31, 13 September 2017




Project Diary


Week one

10/07/2017
  • Meet up
  • Safety and risk assessment forms
  • Review to do lists
  • Safety = Helen
  • Sequencing = Niall
  • Plants = Jade and Sarah
  • Stockroom = Emily, Ryan, and Thomas
  • Arranged lab and workspaces
  • Sorted pipette tips into boxes and autoclaved.
  • Made medium using 25 g/l LB broth. Made medium using 10g/L agar granulated (made up to 400ml water). Then autoclaved. Pyrex class will not smash, cools down quickly/till hand-hot.
  • Chloramphenicol + kanamycin resistance antibiotics: One medium had 100mg/ml kanamycin added (400microlitres to 400ml), the other had 34mg/ml chloramphenicol added (400microlitres to 400ml). Plated 19 plates of each.
  • Transferred tobacco plants (grown on 19/6) into new pots to prevent overcrowding.
  • Organised ourselves into 3 'teams':
  • Team_PlantP = Niall and Ryan
  • Team_TSH = Helen, Emily, and Sarah
  • Team_Luc = Jade and Tom

11/07/2017
Team_PlantP Team_TSH Team_Luc
  • Re-suspended iGEM primers 45 - 52 at 100uM. Created working stock at 10uM.
  • Used Primers in a PCR with Arabidopsis thaliana gDNA to amplify 4 plant promoters (with -ve controls)
  • Ran PCR results on 1% agarose gel with 1x TAE. No success at amplifying desired sequences (empty gel lanes).
  • Resuspend TSH gBlocks to concentration 0.1pmol/ul (v.clean water).
  • Digest TSHantag and TSHantag(his) and introduced into pSB1C3 (plasmid) with EcoR1 and Pst1.
  • Ligation mix preparation, left to ligate overnight.
  • Re-do LB broth and agar plates as we used broth in the agar plates!
  • Planted 16 more pots of tobacco plants.
  • Helen doing safety forms and biosafety poster exercise
  • Made up agar plates inoculated with either kanamycin, chloramphenicol or chloramphenicol, X-gal and IPTG.
  • Transform DNA from iGEM registry - Did not work as the cells used were bad.

12/07/2017
Team_PlantP Team_TSH Team_Luc
  • Redid failed PCR from yesterday and ran on a gel - slightly more success (Primer dimers (probably) in 2 lanes).
  • Niall carried out the first part of 2 SOE-PCRs to convert target nucleotides for BsmBI digestion into non-target nucleotides through site directed mutagenesis. SOE-PCRs used to modify the P19 gene and LUCx5 gene.
  • Ran on gel - gDNA was poor so no bands.
  • Ryan: Performed plasmid minipreps according to QIAprep® Spin Miniprep Kit. Measured the concentrations of each of the DNA samples.
  • Digest and ligation using the P5B1C3g plasmid for golden gate cloning, using both TSHantag and TSHantag-his.
  • Ligation reaction using PCR machine (15 cycles).
  • Transformation of biobrick and golden gate plasmids (ligated 11/7 and 12/7) into competent cells. Grown on chloramphenicol for biobrick, and chloramphenicol + Xgal + IPTG for golden gate.
  • Procedure of transformation: ice (10’), heat shock in water bath at 42degrees (1’), ice (5’), add 1 ml LB broth without antibiotic, shake (1hr at 37 degrees), centrifuge for 1 minute at 13k, plate using resuspension and glass beads.
  • Incubation of plates at 37 degrees overnight.
  • Mini Prep of level 0 parts
  • Transformed DNA from iGEM registry again
  • Made competent E.coli, however the water used had not been autoclaved.

13/07/2017
Team_PlantP Team_TSH Team_Luc
  • Extracted DNA from gel to get p19 and LucX5 DNA.
  • Quantified DNA and stored in freezer for future use in plasmids.
  • Extracted DNA from Arabidopsis thaliana.
  • Quantified DNA.
  • Took two best samples and ran PCR with plant promoter primers (IGEM_45 to IGEM52).
  • Re-do transformations as broth was not added to agar.
  • Steps: ice, heat shock, ice, shake for 1 hour, plates.
  • Did surveys for iGEM toulouse about cholera.
  • Transformed DNA from iGEM registry again as well as one of the level 0 parts mini prepped the day prior (as a test) into competent cells.
  • Made up agar plates inoculated with either kanamycin, chloramphenicol or chloramphenicol, X-gal and IPTG.

14/07/2017
Team_PlantP Team_TSH Team_Luc
  • Ran gels with PDF1p, PR2p, GST6p, and WRKY30p, with gDNAs 2 and 3 (highest DNA concentration samples). All lanes were successful with no contamination, except WRKY which had no result except primer dimers.
  • Cut and digested the gels and purified DNAs - 3 test tubes each with either PDF, PR or GST promoter regions.
  • Measured concentrations of the promoter DNA.
  • Set up PCR of WRKY30p at different temperatures (gradient in the PCR machine). Temperatures 50, 53, 57, and 60 degrees.
  • Ran gels with 8 lanes (4 negative controls, and 4 with one of each of the WRKY temperatures)
  • All 4 samples had primer dimers but no amplified gDNA - conclusion = most likely primers are not specific enough to amplify gDNA
  • TSH 5G/TSH10g plates grew colonies.
  • Redo TSH/H 3:1, TSH/H 5g, TSH 5:1 and biobrick controls for transformations.
  • Incubation over night
  • Made up agar plates inoculated with either chloramphenicol or chloramphenicol, X-gal and IPTG. Reducing the concentration of chloramphenicol from 34 to 17, and doubling the concentration of X-gal.
  • Transformed DNA from iGEM registry again into competent cells.
  • Made a protein gel plate to be used in a future test.

Week two


17/07/2017
Team_PlantP Team_TSH Team_Luc
  • Ran PCRs with WRKY at 52 and 56 degrees for primer annealing. With half and double primer concentration in each, to see if either would prevent primer dimers and allow annealing to DNA.
  • Ran gel and found only primer dimers in every sample. gDNA is fine because the positive control had its band.
  • WRKY primer is ineffective, so we must design another.
  • Plates again did not work. Put them in the incubator at 37 degrees.
  • Possible problems with chloramphenicol
  • Running PCR of TSH 5G and TSH10G colonies.
  • Made gels, on 120 for 50 minutes and they did not work so re-doing them!
  • Re-ran gels, have better results
  • Helen: from incubated plates 1 was successful (TSH 5:1). Took colonies from previous successful plates using 5 ml broth. Left to incubate and shake overnight at 37 degrees.
  • Transformed the universal promoter (plate 1 - 3O) from the iGEM registry as well as GFP made in the mini prep (12/07/17) and a negative control to test the competent cells.
  • Inoculated agrobacterium and E.coli cultures.

18/07/2017
Team_PlantP Team_TSH Team_Luc
  • Designed new WRKY primer
  • Can’t do anything else until level0 plasmids are done to perform minipreps.
  • Performed a mini prep on the one colony that grew successfully (QLAprep Spin Miniprep Kit).
  • Performed PCR on the mini prep, GFP plasmid, and level 0 colonies
  • Ran a gel using the PCR products and the hyperladder 4
  • Helen: Grew bacterial cultures using chloramphenicol and kanamycin antibiotics. 5ml LB broth and 5 ul of antibiotics. Left overnight on 200 RPM at 37 degrees.
  • Grew colonies from plate A (4), B (1), C (4), Rob’s colonies.
  • Re-incubated the agrobacterium overnight as they were not spinning so could not grow.
  • Made some more competent E.coli using previously made competent E.coli as a starting point.

19/07/2017
Team_PlantP Team_TSH Team_Luc
  • Performed minipreps on samples A1 and A2, C1 and C4. Isolated the DNA and measured concentrations of samples A1-A4 and C1-C4 against EB as a blank.
  • Performed restriction digest on P19, Luc, PDF1, PR2 and GST6, according to long protocol in ligase buffer. Put in PCR machine for the process.
  • Performed ligation and gel analysis to see whether the plasid cut and incorporated the recombinant DNA.
  • Minipreps on plates A (level 0) and C (level 1).
  • Digest process and then used PCR using long protocol.
  • Tested level 0 plasmids.
  • Also completed 2 minipreps of GBA2 using QIAprep protocol
  • Did a digest of the plasmid in the water bath at 37 degrees using BsmB1
  • Ran a gel comparing the undigested plasmid and the ones digested with BsmB1
  • Ran a transformation to compare the newly made competent cells with the competent cells made on 12/07/17.
  • The agrobacterium that were grown overnight were used to infiltrate the leaves of tobacco (to be harvested in two days time), by suspending the cells in induction buffer.

20/07/2017
Team_PlantP Team_TSH Team_Luc
  • Transformed bacteria with level 0 plasmid parts - P19, LUCx5, GST-6, PR-2, PDF-1.
  • Performed level 1 restriction digest/ligation with 35S, XVE and NOST.
  • Sarah and Emily: Digestion of biobrick plasmid
  • Ligation reaction for this digest left overnight
  • Helen: Grew colonies from A (Chl)/C (kan)/GBA2 (kan) in the incubator overnight
  • Sarah and Emily: emailed BBC wales.
  • Helen: Fiona Wylie contact. Booked dates for the 7th October and 16th September events as part of our human outreach.
  • Christian from Cardiff_iGEM16 came to talk to us, said that looking at the medals protocol is essential!
  • Checked new vs. old cells that were left to grow overnight. Using GFP and a negative control. The new cells were found to be a lot more competent.
  • Transformed the correct parts from the iGEM registry as well as B1 and B2.
  • Made up more chloromycin and kanamycin plates.
  • Practiced grinding leaves in EZ extraction buffer using a pestle and mortar, to prepare for tomorrow.

21/07/2017
Team_PlantP Team_TSH Team_Luc
  • Investigated P19, LUCx5, PDF, PR, GST colonies for successful transformants - Only identified one transformant for P19. Extracted colony and cultured in LB broth w/ CHL to increase cell number. Repeated with -ve controls. After incubation, performed a PCR with bacterial colony and primers 57+58 and ran products on gel.
  • Repeated restriction digest of P19, LUCx5, PDF1, PR, GST.
  • Transformed E.coli with level 1 plasmid containing 35s, XVE and NOSt and plated cells to grow over the weekend.
  • Minipreps on colonies grown overnight at 37 degrees and in the shaking machine (200 rpm).
  • Minipreps carried out on A/C/GBA2 then put in the team_TSH freezer
  • Sarah and Emily: biobrick transformations into competent cells. The transformed bacteria were then plated out and incubated at room temperature over the weekend.
  • Golden gate level 0 plasmid digest and ligation. Changed some methods: increased level to 1ul of BsmBI. Reduced level of acceptor plasmid from 200ng at 2:1 to 50ng at 1:5. Calculations viewed in HD book.
  • Human outreach aspects: producing a survey investigating people’s perspectives on producing a protein using tobacco plants to treat Grave’s Disease. Dewi put on twitter!! Also Skype call with Washington team to discuss collaborations.
  • Checked the plates grown overnight - B1 and B2 grew very well however the plates from the iGEM registry grew more slowly.
  • Cultures from the B1 and B2 plates were inoculated with kanamycin and left to grow over the weekend in a shaking incubator at 22 degrees.
  • The plants that were infiltrated on 12/07/2017 were prepared by grinding them in a pestle and mortar on ice with EZ extraction buffer, before centrifugation at 13000 rpm for 5 minutes. 1/10 the volume of buffer Z was then added to the supernatant liquid in a fume hood before placing them in the freezer.

24/07/2017
Team_PlantP Team_TSH
  • Inspected colonies - all white with contamination, including the negative control - suspect the plates did not have Chloramphenicol or X-Gal.
  • Re-ran PCR of level 1 plasmid - no bands so must redo transformation.
  • Transformed more competent cells with the level 1 35S-XVE-NosT plasmid, as these had not grown at all. Incubate at 37 degrees overnight.
  • Recombine pGEM-EASY plasmid with PDF, PR, and GST. Geraint will try and transform some cells to see if these work, otherwise they will be transformed in the morning after 22 degree overnight incubation.

  • Survey stuff.
  • Made more competent E.coli using batch #2 as the starting point.

28/07/2017
Team_PlantP Team_TSH Team_Luc
  • Level 0: All P19, LUCx5, PDF1, PR2, GST6 colonies taken from white colonies from previous day turned out to be blue on new plates.
  • Carried out another transformation using PDF, PR, GST, P19 and LUCx5 digests. After transformation, plated cells on old agar plates with IPTG, x-gal and Chl to grow over the weekend.
  • Level 1: Performed another level 1 digest with 35S, XVE and NOSt, transformed cells and grew over the weekend
  • WRKY: New primers proved successful - ran PCR products on gel and carried out DNA extraction from gel. Have now isolated WRKY promoter sequence.
  • Transformations using pGEM (TSH/TSHH) and gblock (TSH/TSHH), grew up the colonies over the weekend

Team_PlantP Team_TSH Team_Luc
  • Level 0: Every colony white AGAIN - old plates may have had poor X-gal. Re-plating the transformed cells from 28/07/17 on fresh plates with functional x-gal to grow overnight.
  • Also re-plating 20 white colonies from P19, LUCx5, PDF, PR, GST on fresh plates to check for successfully transformed cells on plates from 28/07/17.
  • Level 1: No colony growth on plates from 28/07/17… Not sure why, could be that there isn’t enough pGB-a2 plasmid DNA (Ryan vortexed during the mini-prep protocol where he shouldn’t have), maybe kanamycin is killing all the cells? - going to ask Geraint and then potentially do another digest.
  • WRKY: Set up a lvl 0 restriction digest, then transformed cells with product and grew overnight.
  • Prepping for 2pm talk (what is the project? What have we experienced in the practical work? Human outreach aspects?) Colonies grown over weekend from 28/0717
  • Successful transformants showing white colonies from TSHH pGEM, TSHH gblock and TSH gblock. No colonies were visible from TSH pGEM (plates: chl, x-gal, IPTG).
  • Grown on chl 300 ul LB broth and colonies.
  • Colony PCR of TSHH gblock (X), TSHH pGEM (Y), TSH gblock (Z).
  • Ran a gel using the PCR products.
  • Made more chloramphenicol 34 µg/ml plates.
  • Re-transformed the competent cells as was done on 28/7/17 as the negative plates had a lot of colonies on them. This could have been due to the plates used being fairly old. These new transformations were left to grow overnight at 37 degrees celsius.
  • Inoculated B2-1 with kanamycin and rif to grow overnight at 28 degrees celsius. In order to infiltrate tomorrow.

  • Inserted WRKY into pGEM plasmid. Transformed and grew cells - none grew.
  • Set up ligation of pGEM GST, PR, PDF plasmids into level 1 18J plasmid. Transformed cells and Grew cells on plates - some blue colonies, most plates with no growth.
  • Set up sequencing tubes of pGEM versions of PDF, PR, and GST - 50ng/ul in 15ul.
  • PCR:
  • Gel using PCR products from 31/07/17 inconclusive. No negative control used so bands could not be analysed.
  • Therefore, grew colonies from PCR products from 31/07. Only 2 white colonies (2 TSHH gblocks (9 + 10) transformed. 14 of the other colonies failed to transform, remaining blue in colour.
  • Following the transformations, a colony PCR was carried out (2 TSHH gblocks, one blue TSH pGEM, one negative (no DNA), positive control (plasmid)).
  • Ran a gel using the PCR products. No bands were present in the lanes representing the colonies.
  • Level 0 plasmid:
  • Using the level 0 plasmid completed a digest and ligation.
  • Increased BsmB1 volume from 0.5 ul to 1ul. Also increased T4 ligase from 0.5 ul to 1 ul.
  • Plates:
  • Made 16 Chl + x-gal + IPTG and 8 AMP + x-gal + IPTG plates 2 chl + x-gal + IPTG plates used to plate cells from the transformations using the digestion/ligation products from earlier in the day. The plates were grown overnight.
  • pGEM plates:
  • Original TSH pGEM and TSHH pGEM colonies grown, grown further on fresh AMP + x-gal + IPTG plates. 20 colonies from each plate grown on the 2 new plates.
  • Checked the transformations that were redone - they were successful with the negative control plates showing no colonies. #2 and #3 are approximately the same level of competency
  • The agrobacteria containing B2 were infiltrated into the tobacco leaves.

Team_PlantP Team_TSH Team_Luc
  • Performed BsMB1 digest at 55 degrees on all parts PDF, PR, GST, P19 and Luc. Left for two hours with mixture at 55 degrees.
  • Performed ligation separately at 16 degrees for 1 hour 45mins. Negative control had the ligase buffer but no insert.
  • Plated these plates on level 0 Chl plates and grew overnight. -ve control shared between no insert and no ligase.
  • Plates from transformation
  • Plates from 01/08/17 failed to transform. Current thought is that 55 degrees is too hot for the ligation to occur.
  • Therefore, digest and ligation carried out separately when investigating TSH and TSHH gblocks. Digest took place at 55 degrees for 2 hours using buffer 3.1 (10x) BSA, insert (TSH/TSHH gblock), BSMBI, water and P6-18J plasmid. A negative control was also included.
  • Ligation at 16 degrees for 2 hours using T4 ligase buffer, cut vector and insert TSH from original digest and T4 ligase enzyme. T4 ligase enzyme was not incorporated into the negative control.
  • Products of the digest and ligation then transformed and left to incubate overnight.
  • pGEM plates:
  • Colonies grown from original TSH/TSHH pGEM plates grown in broth and left overnight.
  • Designed the luciferin experiment for tomorrow.
  • Calculated the relevant concentration of buffer required for tomorrow.

03/08/2017
Team_PlantP Team_TSH Team_Luc
  • Analysed plates: colonies on every plate including both sides of the negative control. Much more on TSH plates than promoter plates - I did not resuspend the cells efficiently?
  • Picked 5 colonies from each plate for colony PCRs. Grown in LChl for 3 hours.
  • Made another IPTG stock.
  • Digested WRKY at 55 degrees, then ligated at 16 degrees.
  • Created LChl plates with IPTG, and 2x X-Gal.
  • Transformed cells with WRKY digest/ligation product and plated on LChl, IPTG, 2x X-Gal plates.
  • Ran Gel with PCR product from promoter colonies.
  • TSH/H gblock transformations from 02/08 displayed both white and blue colonies after being left in fridge to develop colour. 2 negative controls (1 no ligase/1 no insert), both showed white and blue colonies. White transformants especially apparent on TSH no ligase control. The no insert control showed fewer colonies probably due to inadequate re-suspension.
  • Colonies grown underwent colony PCR in order to extract possible insert DNA.
  • pGEM minipreps:
  • Minipreps of TSH/H pGEM grown overnight.
  • 1st minipreps were at 14 ug/nl and 13 ug/nl.
  • 2nd miniprep concentrations were 27.55 TSH and 62.650 TSHH
  • Sent TSH/H pGEM vectors off for sequencing.
  • Made the buffer for the luciferin experiment - mes 50mM, EDTA 1mM, glucose 0.5%, DMSO 0.5%
  • Pipetted the buffer into the relevant wells then added the leaf disc cuttings. Luciferin was then added at either 1 or 0.5 mM to the relevant wells. The plate was left in the dark for 2 hours before testing on the imager.
  • 1mM luciferin in sodium citrate solution was infiltrated into a whole leaf (control, concentration A or concentration B) in order to image whole leaf samples.
  • Data analysis

Team_PlantP Team_TSH Team_Luc
  • WRKY plates have colonies on them. Unclear whether they are blue or white so left over the weekend in the fridge to develop - will perform colony PCRs on monday.
  • Re-performed digest and ligation of PDF, PR, GST, P19, Luc. Digest at 55 degrees, then denatured at 80 degrees, then ligated at 16 degrees. Transformed cells but did not have time to incubate and plate cells, so left them at room temperature to incubate over the weekend. Plating first thing on monday.
  • 3 white colonies on TSHH gblock plate and 1 on TSH gblocks. Colony PCR on these successful white colonies. Put fridge over the weekend.
  • Need to run a gel on monday and miniprep those that have the insert DNA

  • Streaked the transformed cells from separate digest and ligation of PDF, PR, GST, P19 and Luc. Growing overnight at 37 degrees.
  • Picked 12 colonies from WRKY plate (possible whites) and grew in 1ml LB with 1ul Chl (wrong measurement - got confused with transformations!) - growing for 20hours to make up for the additional volume.
  • Spoke with Jamie: is it worth forgetting the colony PCRs and doing diagnostic digests instead? Also isolate just the uncut plasmid and use that for transformations by digesting and extracting the now linear plasmid?
  • None of the biobrick colonies from Friday grew.
  • Additional colonies grown from original TSH gblock plates miniprepped before PCR.
  • Previous colony PCR’s unsuccessful due to base insertions. . Alternative strategy to miniprep before PCR procedures no working so hoping minipreps will help the PCR.
  • Carried out the luciferin experiment again and carried out the data analysis of it.
  • Transformed the level 1 ligation mix that was left over the weekend in the fridge. The bacteria were spread over 5 agar plates (kan,IPTG,X-gal) to give a better chance of growth. These plates were left overnight in the 37.

08/08/2017
Team_PlantP Team_TSH Team_Luc
  • Screened for blue/white colonies on PDF, PR, GST, P19 and Luc plates. 9, 5, 1, 1 and 0 white colonies, respectively. Picked these cells and grown in 5ml of Chl broth instead of colony PCR due to the low results.
  • Performed colony PCRs of the 12 white WRKY colonies. Used the same colony twice with 58 and 59 primers and also with the WRKY-specific primers.

  • Set-up sequencing reactions for 10/08. Had to grow up more plasmid. These mini-prepped and sent off for sequencing tomorrow.
  • Digest:
  • Level one digest completed using BSA1, the digest included TSH/H, 35S or LexA and NosT. The digest was done at 37 degrees for 3 hours.
  • The enzymes were then heat inactivated at 80 degrees for 15 minutes.
  • T4 ligase was then added and the ligation reaction was done at 16 degrees overnight.
  • Mini-prepped 5 out of the 10 level 1 colonies grown overnight, resuspending them in 30 µl of Elution buffer.
  • These were then digested using BsmB1 before running them on a gel. This gel was very inconclusive, so this digest/gel will need to be redone.

10/08/2017
Team_PlantP Team_TSH Team_Luc
  • Performed digest and ligation (overnight) with some Level 1s: 35S-P19-NosT, PDF-Luc+-NosT, and PR-Luc+-NosT

11/08/2017
Team_PlantP Team_TSH Team_Luc
  • Performed colony PCRs and analysed gels. Inconclusive results - likely worked for P19 but not for GST - hard to compare band sizes with LacZ as they are similar.
  • Sequenced PDF, PR, GST and P19 - GST ok, issues with the others.
  • Only those colonies miniprepped prior to PCR showed bands once the gel had been run.
  • Performed a digest on the biobrick containing the TSH to see if there were 2 bans on the gel, when we ran the gel there were no bands.
  • Level 1:
  • 3LexA/4LexA/135S/35s plates showed both white and blue colonies. These growing in broth and Kan before PCR/miniprep procedures.

  • Transformation to compare #4 vs. #3 of competent cells. Left to grow overnight at 37 degrees.
  • Transformed 35S-OTMV from the iGEM registry (plate 6-14D) as there have been problems with the 35S that has been used. So this is to act as a backup if the level 1 reactions do not work. Left to grow overnight.
  • Re-ran the level 1 digest/gel as was done yesterday but we reduced the digest time to 17 minutes. The bands obtained looked more promising but there is still no correlation between all the different samples tested (there should be as they're all supposedly the same level 1 construct).
  • Inoculated tubes 1,2,3,5 of the old level 1 cultures again (35s,xve,nos-t) to mini prep tomorrow.

  • Level 1 cells had not grown enough so left again for another night.
  • Level0 p19 and LucX5 had white colonies, so they were picked and grown in broth overnight.
  • Checked plates from previous day: batch #4 of competent cells still grew on Cl plates, meaning they have developed Cl resistance (we’ve now thrown them away), and the 35S registry part plates failed to grow colonies

  • Performed PCRs with 2:30 extension time: 5 level 1 GST6 colonies with primers 64 and 41, and 7 PR2 colonies with primers 64 and 41 also. 7 PR2 level 1 colonies with primers 47 and 65. 5 GST level 1 colonies with primers 49 and 65. The level 0 p19 and LucX5 with primers 57 and 58. Level 1 GST-TSH-NosT, GST-TSHH-NosT, and PDF-Luc+-NosT, all with primers 64 and 65.
  • Tom carried out digest and ligation of WRKY DNA to get it into the level 0 plasmid. Ligating overnight.
  • Ran PCRs on gels for 20minutes at 120V, 400A.
  • Redid PCR using 44 and 56 primers for 35S plasmids as negative control showed a band.
  • 2 PCRs using primers 64+56 and 65+44 for 35s colonies and LEXA.
  • Gels from PCR showed differences in banding patterns, and the negative control had a band which could be due to contamination. So re-did this PCR using 64+56 and 65+44 primers again
  • Carried out level 0 reaction with bsmb1 of the g blocks (PR/PDF, PR/GST, GST/PDF, WRKY/PDF) and Ryan and Nialls WRKY. Left at 4 degrees overnight.
  • Checked the transformation to test the new cells. Batch #4.1 have no chl resistance.
  • Grew up liquid cultures of p6-18j to mini prep tomorrow.
  • Plates from previous day did not turn blue, going to re-do the transformation tomorrow alongside the level 0 reactions from today

  • Grown agrobacteria containing pGB:35s-TSHH-NosT and pGB:LexA-TSHH-NosT and 35S:LUC+ overnight
  • Phone call with Phillip Cater and Nicholas Holton from Leaf Systems International. Spoke about the issues with GM pharmaceuticals and the issues of regulations.
  • Looked at the plates from the previous day: the plates grown on Kanamycin had tiny colonies, so they were put back in the incubator, whilst the plates grown on Chloramphenicol had only 2 white colonies on WRKY/PDF and 1 white colony on PR/PDF - these white colonies were inoculated to grow O/N, and also picked into water to be used for colony PCR (primers 57 and 58). The rest of the level 0 plates (on Chloramphenicol) were put in the fridge in the hope that more white colonies might be seen.
  • Colony PCR: picked colonies into 20ul water, denatured at 95 degrees for 5 minutes, then took 2ul forward into a PCR reaction (94 degrees 20 seconds, 56 degrees 20 seconds, 72 degrees 2 minutes).

  • Transformed WRKY level 0 cells again and plated them on Chl plates. Growing at 22 degrees over the weekend.
  • 35S:LUC+, 35S:TSHH3/4 failed to grow sufficiently. LEXA: TSHH was cloudy.
  • Agrobacteria grown overnight resuspended in infiltration buffer (MES, MgCl2, acetosyringone) to OD600:0.5. These were left to incubate at room temperature for 2hr
  • Agrobacteria was then infiltrated into tobacco leaves
  • Watered all plants
  • 3 white colony cultures from yesterday were miniprepped by Sarah

29/08/2017
Team_PlantP Team_TSH Team_Luc
  • Discovered PDF, PR and GST ‘Luc+’ is actually TSHH so every ‘Luc+’ level 1 before the 29/08 is TSHH
  • Did lvl 1 DIG LIG for PDF luc+ Nost, PR2 luc+ Nost and GST luc+ nost
  • Performed a transformation of e.coli with LUC+ to increase luc+ plasmid quantity
  • Grew agrobacterium up in broth with Rif and Kan. Agrobacterium consisted of colonies with lvl1 plasmids for GST TSHH nosT, PDF TSHH nosT and PR TSHH nosT.
  • Picked the WRKY level 0 colonies and grew in broth overnight at 37 degrees.
  • Performed PCR diagnostic on Luc+ samples with Luc+ specific primers and another set with TSH specific primers - Bands present with both, so samples are contaminated and cannot be used.
  • Leaves infiltrated on 25/08 frozen using liquid N2 before grinding of the leaves on ice
  • Buffer EZ was added to the extracts before centrifugation at 13,000 rpm. The supernatant was removed from each sample, 40ul of this was taken as the total sample and 10ul Z buffer was added
  • The rest of the supernatant was used in the protein purification process using the nickel beads.
  • Set up a PCR reaction with primers 57 and 58 on the mini-prepped DNA of WRKY/PDF 1 & 2 and PR/PDF 1
  • Practised pouring protein gels with water and it worked fine. Then moved on to practising with resolving gel and the gel would appear fine but slowly pour out. Managed to get one of the gels working after a while and added the stacking gel too. Put in the fridge to be used tomorrow.
  • Ran a gel of the PCR from this morning… each of the constructs have bands of the right size, so they’re going to be sent for sequencing tomorrow.
  • Inoculated two cultures of B2 in the hope that they’ll grow this time to be used for infiltration.
  • Mini-prepped 6 of the 10 level 1 cultures from Friday to be digested tomorrow.

  • Picked level 1 colonies from GST, PR and PDF (supposed) level 1 plates, but the negative plate had some white colonies so the water we used was indeed contaminated. Picked and grew all white colonies to test them. If they are TSHH also then we will have to redo luc+ level 1s again!
  • Infiltrated the leaves with salicylic acid and/or ethanol at 5% each.
  • Emily set up PCR to isolate luc+ part with primers 22 and 23. This will isolate the luc+ from the spectinomycin plasmid to put into the pSB1C3g.
  • Ran Luc+ samples on gel and extracted the DNA.
  • Measured Luc+ DNA concentrations and set up digest for 30 minutes only due to time with 15minutes to denature. Ligated over the weekend (16 degrees for 4 hours and final hold 4 degrees).
  • Cut off infiltrated leaves and flash froze them. Stored at -80 degrees over the weekend.
  • Results of gel run on 31/08
  • 64+65 = bands at 1800bp, however white colonies show bands at the same positions as the 35s TSH/TSHH minipreps. Also bands at 1000 bp
  • 64+37 = bands visible even when 37 is specific to LexA promoter
  • 44+65 = bands visible but same length as 64+65
  • Protocols write up
  • Transform 35S from the registry- grow it over the weekend.
  • Transformed the level one digest/ligation from yesterday
  • Re-ran the gel from yesterday, bands were all the same as the previous gel: -ve produced no bands, as did sample 9… but samples 5, 6, 7, 8 and 10 all have bands
  • Helped with infiltration
  • Met Jamie to image the LUC assay, but it didn’t show up any results, possibly because the luciferin was left for 3hrs, or because the concentration of Agrobacterium infiltrated into the plants was too low
