OsLEA3, a late embryogenesis abundant protein gene from rice, confers tolerance to water deficit and salt stress to transgenic rice

OsLEA3, a late embryogenesis abundant protein gene from rice, confers tolerance to water deficit... OsLEA3 is a late embryogenesis abundant group 3 protein. The OsLEA3 gene located on chromosome 5 of rice (Oryza sativa L.) includes one intron and two exons and encodes a protein of 200 amino acid residues. Expression analysis revealed that OsLEA3 was induced by water deficit and salt stress. Overexpression of the OsLEA3 gene in the transgenic rice plants allowed us to test the role of the OsLEA3 protein in stress tolerance. The accumulation of the OsLEA3 protein in the vegetative tissues of transgenic rice plants enhanced their tolerance to water deficit and salt stress. These results demonstrate a role for the OsLEA3 protein in stress protection and suggest the potential of the OsLEA3 gene for genetic engineering of stress tolerance. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Plant Physiology Springer Journals

Abstract

OsLEA3 is a late embryogenesis abundant group 3 protein. The OsLEA3 gene located on chromosome 5 of rice (Oryza sativa L.) includes one intron and two exons and encodes a protein of 200 amino acid residues. Expression analysis revealed that OsLEA3 was induced by water deficit and salt stress. Overexpression of the OsLEA3 gene in the transgenic rice plants allowed us to test the role of the OsLEA3 protein in stress tolerance. The accumulation of the OsLEA3 protein in the vegetative tissues of transgenic rice plants enhanced their tolerance to water deficit and salt stress. These results demonstrate a role for the OsLEA3 protein in stress protection and suggest the potential of the OsLEA3 gene for genetic engineering of stress tolerance.
