BL-triggered interactions of CRY2 with TOE1 and TOE2 promote the dissociation of TOE1 and TOE2 from CO, resulting in alleviation of their inhibition of CO transcriptional activity and enhanced transcription of …

WebThe activity of the Lhcb1*2 promoter was higher in the cry1 cry2 mutant than in the cry2 mutant, suggesting that cry1 could be involved in blue-light repression of photosynthetic genes. Surprisingly, the phyA cry1 cry2 triple mutant flowered earlier and showed better response to photoperiod than the cry1 cry2 double mutant, indicating that phyA ...

WebSep 4, 2024 · To investigate whether the cry2:TOE interaction plays a role in flowering regulation, the group created a cry1 cry2 toe1 toe2 quadruple knockout mutant. These plants flowered slightly earlier than the cry1 cry2 mutant, suggesting that cryptochromes promote flowering at least in part through the inhibition of TOEs.
