Abstract: | A partial cDNA clone (CG-1) encoding a sequence-specific DNA-binding protein (CG-1) was isolated from a parsley (Petroselinum crispum L.) cDNA expression library by a DNA-ligand screening. The nucleotide sequence CGCG is a required motif in this protein's binding site. Interestingly, the mRNA coding for CG-1 accumulated rapidly and transiently in parsley cultured cells after treatment with UV-containing white light. Although the target gene(s) for CG-1 has not been identified, its sequence-specific DNA binding and expression pattern, make CG-1 a possible member of a light signal transduction chain in parsley. |
