WRKY转录因子是一类超级基因家族,包含1~2个WRKYGQK核心序列,在植物界数目众多、功能复杂,在植物病原防卫反应中发挥了十分重要的功能。本文综述了WRKY转录因子的发现及在植物与病原体互作中的基本功能,期望为阐明WRKY超家族的功能提供有益的信息。
WRKY transcription factor is a type of supergene family which contains 1 ~ 2 core sequences of WRKYGQK. It has a large number of plant kingdom and complex functions, and plays a very important role in plant defense response. This review summarizes the discovery of WRKY transcription factors and their basic functions in the interaction between plant and pathogen. We hope to provide useful information for elucidating the function of WRKY superfamily.
