Protein related with heat resistance of plants as well as encoding gene and application of protein

The invention discloses protein related with the heat resistance of plants as well as an encoding gene and an application of the protein. The protein related with the heat resistance of the plants is the following (a) or (b): (a) protein consisting of amino acid sequences represented in sequence 1 in a sequence table; (b) protein formed by performing substitution and/or absence and/or addition of one or more amino acid residues on the amino acid sequences represented by the sequence 1, derived from the sequence 1 and related to the heat resistance of the plants. Experiments prove that after heat stress on transgenic plants, the content of malondialdehyde in plant blades and the relative electrical conductivity are obviously lower than those of receptor plants, which proves that the heat stability and the heat resistance of cell membranes of transgenic lines are enhanced. Thus it can be seen that the protein and the encoding gene of the protein have important theoretical and practical significance in cultivating wheat with enhanced heat resistance and other new varieties of plants and have wide application prospect.
