Recently a new member of the blue‐light photoreceptor family, CRY‐DASH, was reported in Arabidopsis , though its distinctive biological functions are still unclear. We characterized the CRY‐DASH gene of tomato and evidenced that its mRNA is expressed in both seeds and adult organs showing diurnal and circadian fluctuations. Moreover, the CRY‐DASH transcription pattern is altered in both in a cry1a mutant and in a transgenic CRY2 overexpressor suggesting that CRY‐DASH regulation must be mediated at least partially by an interaction of CRY1a and CRY2 with the timekeeping mechanism.
