Expression vectors pSSA-K and pSSA-H for expression of SOD and APX in plants to provide stress tolerance

摘要

The present invention relates to a recombinant expression vector, pSSA-K or pSSA-H, containing oxidative stress inducible promoter, such as sweetpotato peroxidase anionic 2 (SWEPA2), a nucleotide encoding superoxide dismutase (SOD) and a nucleotide sequence encoding ascorbate peroxidase (APX) linked to the promoter, antibiotics resistant gene, tobacco etch virus leader sequence, a polynucleotide encloding a transit peptide for chloroplast targeted expression, CaMV 35S transcription terminator, and T-DNA boarder sequence, and a method for preparing multiple stress tolerant transgenic plants using the recombinant expression vector.
