This invention discloses the wheat heat-resistant
protein TaNAC034, its encoding
gene, and its applications, addressing the technical problem of regulating
plant heat resistance. Specifically, it discloses the application of the
protein, a substance regulating the expression of the
gene encoding the
protein, or a substance regulating the activity or content of the protein in any of the following: A1) application in regulating
plant heat resistance and / or application in preparing products that regulate
plant heat resistance; A2) application in regulating plant
dry weight under
heat stress and / or application in preparing products that regulate plant
dry weight under
heat stress; A3) application in regulating plant
fresh weight under
heat stress and / or application in preparing products that regulate plant
fresh weight under heat stress; the protein is any of the following: B1) a protein with the
amino acid sequence shown in Sequence 2; B2) a protein obtained by substituting and / or deleting and / or adding
amino acid residues of the protein in B1) that has more than 80% identity and the same function as the protein shown in B1); B3) a
fusion protein obtained by attaching a
protein tag to the N-terminus and / or C-terminus of B1) or B2). By regulating the expression of the TaNAC034
gene in plants,
heat tolerance can be controlled, which can be used in industrial production.
