| Abstract: | In the previous research, a novel gene GmPOI (GenBank acc. No. HM235775) encoding a Pollen_Ole_e_I conserved domain was identified in roots of soybean drought resistant cv. Jindou 23. In the present study, GmPOI was cloned and functionally characterized. Real-time quantitative PCR indicated that the expression of GmPOI was induced by drought, cold, salt and abscisic acid in wild-type soybean. The soybean plants overexpressing GmPOI showed higher tolerance to drought stress than wild types. We concluded that GmPOI is probably a novel gene that is involved in the response to various stresses in soybean. |
