Heat resistant plants and plant tissues and methods and materials for making and using same

摘要

The subject invention concerns materials and methods for providing plants or plant tissue with increased resistance to heat conditions. Increased resistance of a plant or plant tissue to heat conditions provides for decreased yield losses generally observed at elevated temperatures. One aspect of the invention concerns polynucleotides that encode a mutant plant small subunit of AGPase. The subject invention also comprises a mutant plant small subunit of AGPase encoded by a polynucleotide of the invention. The subject invention also concerns plants comprising a polynucleotide of the invention and method for making the plants.
