STRESS TOLERANT PLANTS AND METHODS THEREOF

摘要

The present invention provides a method and DNA molecules that when expressed in a plant produces transgenic plants with improved abiotic stress tolerance. The invention includes plant expression vectors comprising the DNA molecules, and plants containing such DNA molecules.

主权项

1. A method of generating a transgenic plant with enhanced tolerance to environmental stress comprising the steps of:
a) transforming a plant cell with a DNA construct comprising a promoter that functions in plants, operably linked to a DNA polynucleotide molecule that encodes a protein substantially homologous to a protein selected from the group consisting of SEQ ID NO: 2, SEQ ID NO: 4, SEQ ID NO: 6, SEQ ID NO: 8, SEQ ID NO: 10, SEQ ID NO: 12, SEQ ID NO: 14, SEQ ID NO: 16, SEQ ID NO: 18, SEQ ID NO: 20, SEQ ID NO: 22, SEQ ID NO: 24, SEQ ID NO: 26, SEQ ID NO: 27, SEQ ID NO: 29, SEQ ID NO: 31, SEQ ID NO: 33, SEQ ID NO: 35, SEQ ID NO: 37, SEQ ID NO: 39, SEQ ID NO: 41, SEQ ID NO: 43, SEQ ID NO: 45, SEQ ID NO: 47 and SEQ ID NO: 51, and operably linked to a 3′ termination region; and b) regenerating said plant cell into a fertile transgenic plant; and c) selecting said fertile transgenic plant containing said DNA construct; wherein said fertile transgenic plant exhibits enhanced stress tolerance compared to a plant of a same plant species not transformed to contain said DNA construct.
