Abstract
Methods of increasing the resistance of a crop plant to heat stress and in particular methods of improving the grain yield and quality of crop plants grown under heat stress in the form of increased minimal temperatures are provided. The methods include selecting plants with increased expression of HYR and growing these plants in regions expected to experience minimal temperatures above 25° C. during the growing season. Methods of screening plants for increased resistance to heat stress and methods of producing grain in regions having minimal temperatures of 25° C. or more are also provided.
Claims5
A method comprising obtaining a transgenic rice crop plant comprising a polynucleotide operably connected to a promoter functional in cells of the plant and the polynucleotide encoding and overexpressing a HYR protein comprising SEQ ID NO:
- 1 or a sequence comprising at least 95% identity to SEQ ID NO:
- 1 as compared to the expression of a HYR protein comprising SEQ ID NO:
- 1 or a sequence comprising at least 95% identity to SEQ ID NO:
- 1 in a Nipponbare control plant, and planting the rice crop plant in an area at risk of having average minimal temperatures above 25° C.
