The YABBY family is a class of plant-specific transcription factors comprising a typical N-terminal C2C2-type zinc finger domain and a C-terminal helix-loop-helix YABBY domain. YABBY transcription factors play important roles in multiple biological processes, including polarity establishment in plant leaves, the formation and development of reproductive organs, the response to plant hormone signals, resistance to stress, crop breeding and agricultural production. The aim of this review is to summarize our current understanding of the roles, functions and value of the YABBY family in plants, with particular emphasis on new insights into the molecular and physiological mechanisms involved in the YABBY-mediated modulation of polarity establishment, morphogenesis and development, and phytohormone and stress responses in plants. In addition, we propose that this transcription factor family presents great value and potential for research, application and development in crop breeding and agricultural production in the future.

YABBY家族是一类植物特异性转录因子，包括典型的N末端C2C2型锌指结构域和C末端螺旋-环-螺旋YABBY结构域。YABBY转录因子在多种生物学过程中起着重要作用，包括植物叶片中的极性建立，生殖器官的形成和发育，对植物激素信号的响应，抗逆性，作物育种和农业生产。这篇综述的目的是总结我们目前对YABBY家族在植物中的作用，功能和价值的理解，特别强调对与YABBY介导的极性建立，形态发生和调节有关的分子和生理机制的新见解。发育，植物激素和胁迫反应。此外，
