Suppression of late-flowering and semi-dwarf phenotypes in the Arabidopsis clock mutant lhy-12;cca1-101 by phyB under continuous light.

Photoperiodic flowering in Arabidopsis is controlled not only by floral activators such as GI, CO, and FT, but also by repressors such as SVP and FLC. Double mutations in LHY and CCA1 (lhy;cca1) accelerated flowering under short days, mainly by the GI-CO dependent pathway. In contrast, lhy;cca1 showed delayed flowering under continuous light (LL), probably… CONTINUE READING
