Abstract
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 ferrochelatase.
Claims9
An isolated polynucleotide comprising:
- (a) a nucleotide sequence encoding a polypeptide with ferrochelatase activity, wherein the polypeptide has an amino acid sequence of at least 92% 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:6, or
- (b) the full complement of the nucleotide sequence of (a).
