Abstract

Methods and materials for modulating heat and/or drought tolerance in plants are disclosed. For example, nucleic acids encoding heat and/or drought-tolerance polypeptides are disclosed as well as methods for using such nucleic acids to transform plant cells. Also disclosed are plants having increased heat and/or drought tolerance and plant products produced from plants having increased heat and/or drought tolerance.

First claim

What is claimed is:

1 . A method of producing a plant, said method comprising
growing a plant cell comprising an exogenous nucleic acid, said exogenous nucleic acid comprising a regulatory region operably linked to a nucleotide sequence encoding a polypeptide comprising an amino acid sequences having 90 percent or greater sequence identity to an amino acid sequence of SEQ ID NO: 311, producing a plant from said plant cell, selecting the plant produced from said plant cell for having an increased heat or drought tolerance as compared to a control plant that does not comprise said nucleic acid.

2 . The method of claim 1 , wherein the polypeptide comprises an amino acid sequence having 95 percent or greater sequence identity to the amino acid sequence of SEQ ID NO: 311.

3 . The method of claim 1 , wherein said polypeptide comprises the amino acid sequence set forth in SEQ ID NO: 311.

4 . A method of increasing heat or drought tolerance in a plant, said method comprising
introducing into a plant cell an exogenous nucleic acid, said exogenous nucleic acid comprising a regulatory region operably linked to a nucleotide sequence encoding a polypeptide comprising an amino acid sequences having 90 percent or greater sequence identity to an amino acid sequence of SEQ ID NO: 311, producing a plant from said plant cell, selecting the plant produced from said plant cell for having an increased heat or drought tolerance as compared to a control plant that does not comprise said nucleic acid.

5 . The method of claim 4 , wherein the polypeptide comprises an amino acid sequence having 95 percent or greater sequence identity to the amino acid sequence of SEQ ID NO: 311.

6 . The method of claim 1 , wherein selecting the plant comprises
applying limited water conditions for at least two weeks; and selecting for a plant having increased chronic drought tolerance compared to a control plant that does not comprise said nucleic acid.

7 . The method of claim 4 , wherein selecting the plant comprises applying limited water conditions to said plant for at least two weeks; and
selecting for a plant that has an increase in chronic drought tolerance compared to a control plant that does not comprise said nucleic acid.
