CONSTRUCTS AND METHOD OF USE FOR RICE GLUATAMATE RECEPTOR-LIKE GENES

摘要

Isolated polynucleotides and polypeptides, and recombinant DNA constructs are useful for conferring drought tolerance and/or improved nitrogen use efficiency. Compositions (such as plants or seeds) comprise these recombinant DNA constructs; and methods utilize these recombinant DNA constructs. The recombinant DNA constructs comprise a polynucleotide operably linked to a promoter that is functional in a plant, wherein said polynucleotides encode glutamate receptor polypeptides.

1. An isolated polynucleotide enhancing drought tolerance of a plant, comprising (a) a polynucleotide with a nucleotide sequence of at least 85% sequence identity to SEQ ID NO: 4, 5, 7, 8, 10, 11, 13, 14, 16, 17, 19, 20, 22 or 23; (b) a polynucleotide encoding a polypeptide with an amino acid sequence of at least 90% sequence identity to SEQ ID NO: 6, 9, 12, 15, 18, 21 or 24; or (c) the full complement of the nucleotide sequence of (a) or (b); and wherein the isolated polynucleotide is operably linked to a heterologous regulatory element.
