植物Phytocyanin蛋白家族研究进展

A review on the research progress of the Phytocyanin (PC) protein family

摘要: 质体蓝素（Phytocyanin，PC）是植物特有的一类Ⅰ型小分子蓝铜蛋白，可在植物生长发育及应对逆境胁迫过程中发挥调控作用。但目前对PC蛋白的功能研究较为有限，其分子作用机制尚不清楚。本文综述了PC蛋白的结构特征、分类及其基因的表达模式，并对近年来PC蛋白调控植物生长发育、应对生物及非生物胁迫方面的研究进展进行了总结。此外，对未来研究方向及面临的挑战进行了讨论，旨在为进一步理解PC蛋白的分子作用机制及植物抗逆品种的选育提供参考。

Abstract: Phytocyanins (PCs) are a class of plant-specific typeⅠsmall-molecule blue-copper proteins involved in regulating plant growth, development, and stress responses. Despite their importance, functional analysis of PC proteins remains limited, and their molecular mechanisms are not fully understood. This review examines the structural features, classification, and expression patterns of PC proteins. In addition, it summarizes recent advancements in the study of PC proteins, focusing on their roles in plant growth, development, and responses to biotic and abiotic stresses. Unresolved issues and challenges in PC research are also discussed. This work aims to provide a theoretical reference for understanding the molecular mechanisms of PC proteins and for breeding stress-resistant crop cultivars.
