IDA mature polypeptide plant aging accelerator, preparation method and applications thereof

The present invention provides an IDA mature polypeptide plant aging accelerator, a preparation method and applications thereof, and belongs to the field of plant aging accelerators, wherein the IDA mature polypeptide plant aging accelerator can accelerate the aging of the plant leaf and accelerate the aging, and does not have other bad phenotypes. According to the present invention, the functional component of the IDA mature polypeptide plant aging accelerator is an IDA mature polypeptide, wherein the amino acid sequence of the IDA mature polypeptide is Pro-Ile-Pro-Pro-Ser-Ala-Pro-Ser-Lys-Arg-His-Asn; and the IDA mature polypeptide plant aging accelerator comprises the IDA mature polypeptide and a 2-(N-morpholine)ethane sulfonic acid solution, wherein the 2-(N-morpholine)ethane sulfonic acid solution is formed by dissolving a 2-(N-morpholine)ethane sulfonic acid monohydrate in a MS liquid culture medium, and the IDA mature polypeptide plant aging accelerator can be used to promote plant aging.
