WebSep 21, 2024 · Similar maxima were also observed for mutant cry1cry2 irrespective whether or not the seedlings were raised in darkness or blue light (Fig. 6b). Even though the stimulus–response curves of cry1cry2 were somewhat irregular, it became apparent that the cryptochrome mutant had still retained responsiveness to MFs. 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 ...
In plants, cryptochromes mediate phototropism, or directional growth toward a light source, in response to blue light. This response is now known to have its own set of photoreceptors, the phototropins. Unlike phytochromes and phototropins, cryptochromes are not kinases. Their flavin chromophore is reduced by light and transported into the cell nucleus, …
