Advances in the Regulation of Plant Growth, Development and Stress Physiology by Small Peptide Hormones

doi:10.13560/j.cnki.biotech.bull.1985.2022-1468

Abstract

Abstract:

Small peptide hormones are usually referred to as peptides containing 5 to 100 amino acids in length. In plants, the contents of small peptide hormones are very low, the molecular weight is small, the quantity is large, and the source and processing mechanism is complex. This gives small peptides a variety of biological functions. They can bind to receptors at very low concentrations, regulate physiological processes such as cell division and growth, tissue and organ differentiation, flowering and fruiting, maturation and senescence, and coordinate plant responses to various stress environments. As an important medium of signal transduction among cells, the molecular mechanism of small peptide hormones in regulating growth and development is the hotspot and front topic in Botany. First the research progress of the structure, synthesis, classification and function of small peptide hormones were systematically reviewed. Furthermore, the research progress of CIF, CLE, RALFs, PSK, SYS in regulating plant growth and development and stress physiology was emphatically summarized, and the application prospect of plant small peptide hormones was outlined, which may provide an important theoretical basis for the in-depth research, development and application of plant small peptide hormones.

Key words: small peptide hormones, receptor, growth and development, stress physiology, CLE, RALFs, PSK, CIF
