Abiotic stresses have already exhibited the negative effects on crop growth and development, thereby influencing crop quality and yield. Therefore, plants have developed regulatory mechanisms to adopt against such harsh changing environmental conditions. Recent studies have shown that zinc finger protein transcription factors play a crucial role in plant growth and development as well as in stress response. C2H2 zinc finger proteins are one of the best-studied types and have been shown to play diverse roles in the plant abiotic stress responses. However, the C2H2 zinc finger network in plants is complex and needs to be further studied in abiotic stress responses. Here in this review, we mainly focus on recent findings on the regulatory mechanisms, summarize the structural and functional characterization of C2H2 zinc finger proteins, and discuss the C2H2 zinc finger proteins involved in the different signal pathways in plant responses to abiotic stress.
非生物胁迫已经对作物的生长和发育产生了负面影响，从而影响了作物的质量和产量。因此，植物已经发展出了调节机制来适应这种恶劣的环境变化条件。最近的研究表明，锌指蛋白转录因子在植物的生长发育以及在应对胁迫方面起着至关重要的作用。C2H2 锌指蛋白是研究最多的类型之一，它们在植物非生物胁迫反应中表现出多种功能。然而，植物中的 C2H2 锌指网络很复杂，需要在非生物胁迫反应中进一步研究。在这篇综述中，我们主要关注关于调节机制的最新发现，总结 C2H2 锌指蛋白的结构和功能特征，并讨论参与植物应对非生物胁迫不同信号通路的 C2H2 锌指蛋白。
