Plant Chassis

Parts
Figure 7. a) Graphic representation of the first part of the designed genetic circuit Red/ far-red toggle-switch, when activated, will activate luciferase transcription. To do so, PIF6 is fused to a DNA-binding domain (E), which binds to Etr8 operator. Moreover, PhyB is fused to an activator domain (VP64) and a nuclear location sequence (NLS). b) Conformation of the proteins which belong to genetic toggle switch. c) When irradiated with 660nm light, PhyB changes its conformation and this complex is recruited to PIF6 at the promoter site. The polymerase III will recognize the activation domain and the transcription will begin. Only upon absorption of a far-red photon the interaction between PhyB and PIF6 is terminated, resulting in a shut-off of gene expression.
Method
An agroinfiltration and subsequent luciferase assay were performed in order to study gene expression at transcriptional level. To do so, the construct containing the E-PIF6 and PhyB-VP16 transcriptional units was transformed, together with the chimeric promoter nearby the luciferase gene transcriptional unit, by Agrobacterium into N. benthamiana leaves (Figure 7a and 7c). The final Optical Density of optogenetic constructs was 0,1. Several treatments were performed in order to test the toggle switch.
