Red light cryptochrome
Web10. feb 2016 · In plants, many types of photoreceptors have been identified (Fig. 1 ): phytochrome (phy), and cryptochrome (cry) and phototropin (phot) are known as major red/far-red and blue light receptors, respectively. WebABSTRACT Arabidopsis cryptochrome 2 (CRY2) is a blue light receptor that mediates light inhibition of hypocotyl elon-gation and long-day promotion of floral initiation. CRY2 is known to undergo blue light-dependent phos-phorylation, which is believed to serve regulatory roles in the function of CRY2.
