Abstract:

Plant endogenous polypeptides are composed of natural amino acids in different composition and arrangement from the precursor proteins cut into mature polypeptides, which play biological function in development and stress response after secreted outside the cells and recognized by their receptors. The plant endogenous polypeptide family PIP(PAMP induced secret peptide)/PIP-Like(PIPL)contains SGPS and GxGH motifs recognized by receptor like kinase 7(RLK7), and plays important roles in pathogen resistance, virus resistance, salt resistance and development. Here, we review the signal transduction pathways of PIP/PIPL family polypeptides in the process of resistance to stress and development, discuss important unsolved scientific issues, and prospect possible applications, aiming to provide the references on further researches on PIP/PIPL.

Key words: PIP/PIPL, RLK7, signal transduction, stress, development
