Confirmation whether sod2 were inserted into pYES2 plasmid.
The front and the back part of the intron of sod2 were separately amplified by PCR. The forward primer of sod2 located back the intron contained the sequence of reverse Primer in the front of intron as an adapter.
Using these two PCR products, fusion PCR was performed.
The completed PCR product of the coding region of sod2 was integrated into pYES2 plasmid and transfered the resultant plasmid into E.coli. Plasmid extraction was performed from the transformed E. coli . Using the restriction enzyme used to ligate the PCR product of sod 2 with pYES2 Plasmid, the plasmid extracted from E. coli was cut and the length was confirmed by electrophoresis.The length of pYES2 plasmid is 5856bp.
These result showed that sod2 was introduced into pYES2 extracted colony 2, 3, 4 and 8. S. cerevisiae BY4742 was transformed with the plasmid.

Confirmation that S. cerevisiae expressing sod2 acquired salt tolerance
The growth of S. cerevisiae BY4742 cells expressing sod2 was tested on plates containing sodium.
This figure shows that S. cerevisiae (sod2) cells that overexpress the sod2 product is more survived on SD-ura medium supplemented with 4.0 % (w/v) NaCl than the counterpart control S. cerevisiae transformed with an empty vector.
