A METHOD TO ENHANCE MULTIPLE ABIOTIC STRESS TOLERANCE OF CROP PLANTS BY OVER-EXPRESSION OF CYSTATHIONINE-β-SYNTHASE DOMAIN CONTAINING GENE AND CYSTATHIONINE-β-SYNTHASE DOMAIN CONTAINING GENE THEREFOR

摘要

The present invention relates to CBS domain containing genes of Pokkali (Oryza sativa L.) rice having relative expression ratio (fold change, that is, stress vs. control plant) above 2.5 folds and being capable of up-regulating expression of CBS domain containing gene when grown under 200 mM NaCl stress, and capable of substantially enhancing multiple abiotic stress tolerance of plants when overexpressed with CBS domain containing gene even under conditions of high concentration of NaCl, ZnCl₂, and methyl viologen (MV) stress. In one embodiment, it relates to a process for isolation of CBS domain containing gene. It also relates to a method for overexpressing the CBS domain containing gene. It further relates to an overexpressed transgenic tobacco plant grown from overexpressed transgenic tobacco leaf.
