Polyamines (PAs) are nitrogenous and polycationic compounds containing more than two amine residues. Numerous investigations have demonstrated that cellular PA homeostasis plays a key role in various developmental and physiological processes. The PA balance, which may be affected by many environmental factors, is finely maintained by the pathways of PA biosynthesis and degradation (catabolism). In this review, the advances in PA transport and distribution and their roles in plants were summarized and discussed. In addition, the interplay between PAs and phytohormones, NO, and HO were detailed during plant growth, senescence, fruit repining, as well as response to biotic and abiotic stresses. Moreover, it was elucidated how environmental signals such as light, temperature, and humidity modulate PA accumulation during plant development. Notably, PA has been shown to exert a potential role in shaping the domestication of rice. The present review comprehensively summarizes these latest advances, highlighting the importance of PAs as endogenous signaling molecules in plants, and as well proposes future perspectives on PA research.
多胺（PAs）是含有两个以上胺残基的含氮多阳离子化合物。大量研究表明，细胞内多胺稳态在各种发育和生理过程中起关键作用。多胺平衡可能受多种环境因素影响，通过多胺生物合成和降解（分解代谢）途径得以精细维持。在本综述中，总结并讨论了多胺在植物中的运输和分布及其作用的研究进展。此外，还详细阐述了在植物生长、衰老、果实成熟以及对生物和非生物胁迫的响应过程中，多胺与植物激素、一氧化氮和过氧化氢之间的相互作用。此外，还阐明了光、温度和湿度等环境信号如何在植物发育过程中调节多胺积累。值得注意的是，多胺已被证明在塑造水稻驯化过程中发挥潜在作用。本综述全面总结了这些最新进展，强调了多胺作为植物内源性信号分子的重要性，并提出了多胺研究的未来展望。
