Soluble and microsomal glutatione S-transferase activities in pea seedlings (Pisum sativum L.).

abstract：:During a search for genes with induced or enhanced expression in the early stages of development of stem-borne nodules on Sesbania rostrata, a cDNA with homology to chalcone reductase (CHR) genes was isolated. Here, we describe the characterization of a full-length CHR cDNA (Srchr1) and the pattern of CHR transcript a...
