Abstract

We characterized a full-length cDNA of CaCOP1 from pepper. Phylogenetic analysis based on the deduced amino acid sequence of CaCOP1 cDNA revealed high sequence similarity to the COP1 gene in Oryza sativa (84% identity). CaCOP1 shares high sequence identity with regulatory protein in Arabidopsis (84%), constitutively photomorphogenic 1 protein in Pisum sativum (81%) and COP1 homolog in Lycopersicon esculentum (79%). CaCOP1 gene exists single copy in the chili pepper genome. Expression of CaCOP1 was reduced in response to inoculation of non-host pathogens. The expression of this gene under abiotic and oxidative stresses was investigated, including 200 mM NaCl, 200 mM mannitol, cold ($4^{\circ}C$), 100 ${\mu}M$ abscisic acid (ABA), and 10 mM hydrogen peroxide ($H_2O_2$). CaCOP1 was induced significantly 3 h after low temperature treatment but not by dehydration or high salinity. Moreover, CaCOP1 was not induced by plant hormone ABA. These observations suggest that CaCOP1 gene plays a role in abiotic stress and may be belong to ABA-independent regulation system.
