Abstract
A cDNA clone containing a catalase (CAT1) gene, designated PgCat1, was isolated from Panax ginseng C.A. Meyer (Korean ginseng). PgCat1 is predicted to encode a precursor protein of 492 amino acid residues, and its sequence shares high degrees of homology with a number of other CAT1s. Genomic DNA hybridization analysis indicated that PgCat1 represents a multi-gene family. Reverse transcriptase (RT)-PCR results showed that PgCat1 expressed at different levels in leaves, stem, roots of P. ginseng seedlings. Different stresses, heavy metals, plant hormones, osmotic agents, high light irradiance, abiotic stresses, triggered a significant induction of PgCat1. The positive responses of PgCat1 to the various stimuli suggested that P. ginseng PgCat1 may help to protect the plant against reactive oxidant related environmental stresses.
