DROUGHT TOLERANT PLANTS AND RELATED CONSTRUCTS AND METHODS INVOLVING GENES ENCODING SELF-INCOMPATIBILITY PROTEIN RELATED 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 an SIPR polypeptide.

主权项

1. A plant comprising in its genome a recombinant DNA construct comprising a polynucleotide operably linked to at least one regulatory element, wherein said polynucleotide encodes a polypeptide having an amino acid sequence of at least 50% sequence identity, based on the Clustal V method of alignment, when compared to SEQ ID NOS: 18, 20, 22, 24, 26, 28, 30, 32 or 34, and wherein said plant exhibits increased drought tolerance when compared to a control plant not comprising said recombinant DNA construct.
