ABSTRACT 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.

模型植物和作物中的 WRKY 转录因子家族

摘要 开花植物中的 WRKY 基因家族编码一大群转录因子 (TF)，它们在各种应激反应、发育和生理过程中发挥重要作用。在这篇综述中，我们提供了关于模型植物和经济相关作物中 WRKY TF 研究的全面截图。具体而言，我们讨论了 WRKY 转录因子的发现历史和功能表征、分类和进化历史、3D 结构和生理功能。基于先前对拟南芥和水稻等模式植物中 WRKY 基因的功能研究，我们总结了 WRKY TFs 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 WRKY TF 在重要作物中的表征和功能研究。
