Abstract

The adaptation of plants to land requires sophisticated biological processes and signaling. Transcription factors (TFs) regulate several cellular and metabolic activities, as well as signaling pathways in plants during stress and growth and development. The WUSCHEL-RELATED HOMEOBOX (WOX) genes are TFs that are part of the homeodomain (HD) family, which is important for the maintenance of apical meristem, stem cell niche, and other cellular processes. The WOX gene family is divided into three clades: ancient, intermediate, and modern (WUS) based on historical evolution linkage. The number of WOX genes in the plant body increases as plants grow more complex and varies in different species. Numerous research studies have discovered that the WOX gene family play a role in the whole plant's growth and development, such as in the stem, embryo, root, flower, and leaf. This review comprehensively analyzes roles of the WOX gene family across various plant species, highlighting the evolutionary significance and potential biotechnological applications in stress resistance and crop improvement.

摘要

植物对陆地环境的适应需要复杂的生物学过程和信号传导。转录因子（TFs）在植物应激、生长和发育过程中调节多种细胞和代谢活动以及信号通路。WUSCHEL相关同源框（WOX）基因是属于同源异型域（HD）家族的转录因子，对顶端分生组织、干细胞龛以及其他细胞过程的维持至关重要。基于历史进化联系，WOX基因家族分为三个分支：古老分支、中间分支和现代（WUS）分支。随着植物变得更加复杂，植物体内WOX基因的数量会增加，并且在不同物种中有所不同。大量研究发现，WOX基因家族在植物的整个生长和发育过程中发挥作用，例如在茎、胚、根、花和叶中。本综述全面分析了WOX基因家族在各种植物物种中的作用，突出了其进化意义以及在抗逆性和作物改良方面潜在的生物技术应用。
