TaSPDT protein as well as coding gene and application thereof

The invention discloses a TaSPDT protein as well as a coding gene and application thereof. The invention belongs to the technical field of biology, and particularly relates to TaSPDT protein and a coding gene and application thereof. The protein provided by the invention is any one of the following proteins: a protein with an amino acid sequence as shown in SEQ ID No.4, SEQ ID No.5 or SEQ ID No.6; or the protein obtained by substitution and/or deletion and/or addition of amino acid residues of the protein has 80% or more of identity and has the function of regulating and controlling the growth and development performance of wheat and the phosphorus accumulation amount of seeds; or a fusion protein obtained by connecting the N terminal or/and the C terminal of the protein with a protein tag. By regulating and controlling the activity and/or content of the protein TaSPDT in the target plant, or/and the expression quantity of the coding gene of the protein, the growth and development performance of the wheat and
