Isolation and characterization of homologues of plant blue-light photoreceptor (cryptochrome) genes from the fern Adiantum capillus-veneris

Mol Gen Genet. 1998 Sep;259(4):345-53. doi: 10.1007/s004380050821.


Many blue-light mediated physiological responses have been studied in the fern Adiantum capillus-veneris. We have isolated genomic clones encoding sequences similar to those encoding blue-light photoreceptors (cryptochromes) in higher plants using the Arabidopsis CRY1 cDNA as a probe, and these positive clones fall into five independent groups. Using RACE procedures, we obtained full-length cDNA sequences for three of these five groups. The deduced amino acid sequences include the photolyase-homologous domain in the N-terminal half, and they also contain a C-terminal extension of about 200 amino acids in length. These structural features indicate that the genes indeed encode Adiantum cryptochromes and represent a small gene family having at least three members.
