Abstract
The invention belongs to the technical field of biotechnology and botany, and particularly relates to a small peptide for improving abiotic stress tolerance of crops and application of the small peptide, and the small peptide is GhIDL02 and / or GhPIPL7. The amino acid sequence of the GhIDL02 is as shown in SEQ ID NO. 1; the amino acid sequence of the GhPIPL7 is as shown in SEQ ID NO. 2. According to the method, the small peptide GhIDL02 or GhPIPL7 is exogenously applied, so that the hormone-like effect is quickly exerted, the salt tolerance of the cotton is remarkably improved, and the adverse effect of a chemical regulating agent on the environment is avoided. Through a research technology combining bioinformatics and molecular biology, the positive regulation effect of the GhIDL02 and GhPIPL7 small peptides under salt stress is confirmed for the first time, and by activating an MAPK signal channel, the steady state of cotton sodium and potassium ions is maintained, the salt tolerance of cotton is improved, and a theoretical basis and technical support are provided for green development of an agricultural biotechnology.
