摘　要：

表皮模式建成因子EPF/EPFL (EPIDERMAL PATTERNING FACTOR/EPF-LIKE) 家族是植物中特有的富含半胱氨酸的一类小分泌肽。EPF/EPFL 家族通常作为配体与特定受体结合，激活下游信号途径，从而参与植物的生长发育及非生物胁迫响应等重要的生理过程。本文综述了EPF/EPFL 家族成员的进化、结构特征，重点介绍了其对植物生长发育以及非生物胁迫响应的调控作用，讨论了相关研究的重要性并对有待解决的问题进行了展望，旨在为进一步研究EPF/EPFL 家族基因的功能提供一定的参考。

Abstract:

The EPF/EPFL (EPIDERMAL PATTERNING FACTOR/EPF-LIKE) family genes, exclusive to plants,
are a group of small secreted peptides rich in cysteine. Typically functioning as ligands, the EPF/EPFL family binds to specific receptors, activating downstream signaling pathways and thereby participating in important physiological processes, such as plant growth and development as well as responses to abiotic stress. This review summarizes the evolution and structural characteristics of EPF/EPFL family members, with a focus on the regulatory roles in plant growth and development as well as responses to abiotic stress, discusses the significance and outlines unresolved issues, aiming to provide a reference for further research on the functions of EPF/EPFL family genes.
