Abstract

Abstract:

Pipecolic acid（Pip） is a heterocyclic non-protein amino acid serving as precursor for the biosynthesis of biological metabolites. Structurally， the six-membered cyclic motif consists of five carbons and one nitrogen atom. Pip is a cyclic amino acid derived from lysine， in recent years， it has attracted attention in plant research. This review summarized the discovery， biosynthesis， biological functions， and action mechanisms of pipecolic acid， as well as its applications in agricultural production， and put forward prospects for future research directions aiming to establish a foundation for the potential application.

Key words: pipecolic acid, non-protein amino acids, plants, biological functions, action mechanisms
