CCT overexpression mutant shows____

#Unit 6. System Physiology – Plant

CCT overexpression mutant lack the sequester binding site with the COP1/SPA1, therby no longer ability to prevent degradation of HY5
The CCT overexpression mutant shows different responses in the light as well as in the dark
CCT overexpression donot have the N-terminus, CCT region can’t adopt an active conformation and donot allows the binding with COP1/SPA1, thereby donot allows the degradation of HY5 protein
In the absence of the photosensory N terminus as in the truncation mutant , the CCT region can adopt an active conformation that sequesters COP1/ SPA1 in the absence of light, thereby promoting an increase in HY5 protein levels and transcription of key morphogenic genes
