Drought tolerant plants and related constructs and methods involving genes encoding DTP21 polypeptides

摘要

Isolated polynucleotides and polypeptides and recombinant DNA constructs useful for conferring drought tolerance, compositions (such as plants or seeds) comprising these recombinant DNA constructs, and methods utilizing these recombinant DNA constructs. The recombinant DNA construct comprises a polynucleotide operably linked to a promoter that is functional in a plant, wherein said polynucleotide encodes a DTP21 polypeptide.

主权项

1. A plant comprising in its genome a recombinant DNA construct comprising a polynucleotide operably linked to at least one heterologous regulatory element, wherein said polynucleotide comprises a nucleotide sequence selected from the group consisting of:
(a) a nucleotide sequence encoding a polypeptide with drought tolerance activity, wherein the polypeptide has an amino acid sequence of at least 90% sequence identity, based on the Clustal V method of alignment with pairwise alignment default parameters of KTUPLE=1, GAP PENALTY=3, WINDOW=5 and DIAGONALS SAVED=5, when compared to SEQ ID NO:27; (b) a nucleotide sequence encoding a polypeptide wherein the amino acid sequence of the polypeptide comprises SEQ ID NO:27; and (c) a nucleotide sequence comprising SEQ ID NO:26;and wherein said plant exhibits increased drought tolerance when compared to a control plant not comprising said recombinant DNA construct.
