Cryptochrome arabidopsis
WebWe have identified an Arabidopsis photomorphogenic mutant, sub1 , which exhibits hypersensitive responses to blue light and far-red light. Genetic analyses indicate that SUB1 functions as a component of a cryptochrome signaling pathway and as a modulator of a phytochrome signaling pathway. The SUB1 gene encodes a Ca 2+ -binding protein that ...
