The WRKY gene family in flowering plants encodes a large group of transcription factors (TFs) that play essential roles in diverse stress responses, developmental, and physiological processes. In this review, we provided a comprehensive screenshot about the studies on WRKY TFs in model plants and in crops of economical relevance. Specifically, we discussed the history of discovery and functional characterization, classification, and evolutionary history, 3D structure and physiological functions of WRKY transcription factors. Based on the previous functional studies of WRKY genes in model plants such as Arabidopsis and rice, we summarized various roles of WRKY TFs in a broad range of biological processes as well as their degradation process. We also discussed the characterization and functional studies of WRKY TFs in important crops. Considering the rapid progress of high-throughput techniques, especially genomics and transcriptomics, which have been instrumental in advancing our understanding of the crop genomes, we comment one-by-one on the applications of a suite of new and high-throughput techniques to accelerate the studies of WRKY genes in crops.

模型植物和农作物中的WRKY转录因子家族

开花植物中的WRKY基因家族编码一大批转录因子（TFs），这些转录因子在各种胁迫反应，发育和生理过程中起着至关重要的作用。在这篇评论中，我们提供了有关模型植物和经济相关作物中WRKY TFs研究的综合屏幕截图。具体来说，我们讨论了WRKY转录因子的发现和功能表征，分类和进化史，3D结构和生理功能的历史。基于以前的WRKY基因在拟南芥等模型植物中的功能研究在水稻和大米中，我们总结了WRKY TF在广泛的生物过程及其降解过程中的各种作用。我们还讨论了重要作物中WRKY TF的表征和功能研究。考虑到高通量技术（尤其是基因组学和转录组学）的快速进步，这些技术有助于增进我们对作物基因组的了解，因此，我们对一套新的高通量技术的应用进行逐一评论，以加速作物中WRKY基因的研究。
