Abstract
Provided are isolated polynucleotides and polypeptides, and recombinant DNA constructs that are useful for conferring improved drought tolerance and yield in a plant. Also provided are genome edited plants, or plants expressing a recombinant DNA construct, having improved drought tolerance and yield. Further provided are methods for improving drought tolerance and yield by introducing a genome edit in a plant or expressing a recombinant DNA construct in a plant.
Claims14
A modified plant or modified seed comprising an increased expression of at least one polynucleotide encoding a polypeptide comprising an amino acid sequence that is at least 95% identical to SEQ ID NO:
- 9 wherein the modified plant or plant grown from the modified seed has improved drought tolerance when compared to a control plant.
A method of increasing drought tolerance in a plant, the method comprising:
- (a) introducing in a regenerable plant cell a targeted genetic modification at an endogenous genomic locus encoding a polypeptide comprising an amino acid sequence that is at least 95% identical to SEQ ID NO:
- 9, the targeted genetic modification introducing a modification increasing expression or activity of the polypeptide;
- and
- (b) generating the plant, wherein the plant comprises the targeted genetic modification and has increased drought tolerance as compared to a control plant not comprising the targeted genetic modification.
A method of increasing drought tolerance in a plant, the method comprising:
- (a) expressing in a regenerable plant cell, a polynucleotide operably linked to at least one heterologous regulatory element, the polynucleotide encoding a polypeptide comprising having an amino acid sequence that is at least 95% identical to SEQ ID NO:
- 9;
- and
- (b) generating a plant from the regenerable plant cell, wherein the plant comprises in its genome the polynucleotide operably linked to the at least one heterologous regulatory element and has increased drought tolerance as compared to a control plant not comprising the polynucleotide operably linked to the at least one heterologous regulatory element.
