Abstract: A protein provided is: a) a protein with an amino acid sequence as shown in amino acids 1-264 of SEQ ID NO: 1; b) a protein that is associated with disease resistance and obtained after an amino acid sequence as shown in amino acids 1-264 of SEQ ID NO: 1 in a Sequence Listing is subjected to substitution and/or deletion and/or addition of one or several amino acid residues; c) a protein with an amino acid sequence as shown in SEQ ID NO: 1; or d) a protein that is associated with disease resistance and obtained after the amino acid sequence as shown in SEQ ID NO: 1 in the Sequence Listing is subjected to substitution and/or deletion and/or addition of one or several amino acid residues. Experiments demonstrate that the protein associated with disease resistance and the encoding gene thereof can be used to enhance plant disease resistance.

Abstract: Provided are applications of protein VdAL in improving the output, product quality and drought resistance of a plant and in improving fruit coloring of the plant. The protein VdAL is selected from one of A1) to A3): A1), protein having an amino acid sequence that is 1; A2) protein that is derived from A), that has same functions and that is obtained by substituting and/or deleting and/or adding one or several amino acid residues for, from or to the sequence 1; and A3) fusion protein obtained by connecting labels to an N end and/or a C end of A1) or A2).
