General Information Comment Organism
metabolism molybdenum-cofactor sulfurase is a key regulator of abscisic acid biosynthesis Arabidopsis thaliana
physiological function enzyme overexpression in transgenic tobacco can enhance drought tolerance. Enzyme overexpressing tobacco seedlings show lower transpirational water loss than that of nontransgenic seedlings in the same period under normal conditions. Transgenic plants show less wilting, maintain higher water content and better cellular membrane integrity, accumulate higher quantities of abscisic acid and proline, and exhibit higher activities of antioxidant enzymes, i.e., superoxide dismutase, catalase, peroxidase and ascorbate peroxidase, as compared with control plants Arabidopsis thaliana
