Recently a new member of the blue-light photoreceptorfamily, CRY-DASH, was reported in Arabidopsis, though itsdistinctive biological functions are still unclear.

Abstract
Recently a new member of the blue-light photoreceptorfamily, CRY-DASH, was reported in Arabidopsis, though itsdistinctive biological functions are still unclear. We characterizedthe CRY-DASH gene of tomato and evidenced that itsmRNA is expressed in both seeds and adult organs showing diurnaland circadian fluctuations. Moreover, the CRY-DASH transcriptionpattern is altered in both in a cry1a mutant and in atransgenic CRY2 overexpressor suggesting that CRY-DASHregulation must be mediated at least partially by an interactionof CRY1a and CRY2 with the timekeeping mechanism.File in questo prodotto:
