Abstract:

Plants harness many endogenous signal molecules,including hormones and polypeptides,to orchestrate developmental processes and responses to various environmental stresses. Peps are a class of 20-30 amino acid-long polypeptides that are widely distributed among angiosperms plant species. Peps can be perceived by plasma membrane-associated PEPR receptors and play important roles in multiple aspects of plant growth and defense. It has been reported that Peps are critical for plant defense against biological stresses such as pathogen infection and insect biting,as well as for plant tolerance to abiotic stresses such as high salinity. Moreover,Peps have also been shown to regulate the plant growth and development such as root elongation and leaf senescence. Here,we review recent advances in the generation of Peps,perception of receptor,signal transduction and other biological functions. We also discuss and prospect important unsolved scientific issues in Pep signaling and its potential applications in practice,aiming to provide reference for researchers in this field.

Key words: Pep, PEPR, small peptide, signaling transduction
