RWP-RK蛋白家族是一组含有RWP-RK DNA结合域的转录因子。这个领域是一个古老的主题，出现在绿色植物--绿色植物--建立之前，由绿藻和陆地植物组成。该区域在其他王国中大多不存在，但在病毒科中广泛分布。在绿藻、地钱和几种被子植物中，RWP-RK蛋白在氮反应和有性繁殖相关过程中发挥重要作用，这些似乎是无关的现象，但在自养生物中可能是相互依赖的。与RWP-RK蛋白在这些生物中相关但多样化的作用一致，RWP-RK蛋白家族似乎在藻类和陆地植物谱系中密集但独立地扩展。因此，苔藓植物RWP-RK蛋白在建立RWP-RK蛋白家族的进化过程中占有独特的地位。本文综述了病原菌中RWP-RK蛋白家族的研究现状，并讨论了苔藓植物RWP-RK蛋白在阐明RWP-RK蛋白家族多样性与获取适应陆地环境的复杂机制之间的关系方面的重要意义。
The RWP-RK protein family is a group of transcription factors containing the RWP-RK DNA-binding domain. This domain is an ancient motif that emerged before the establishment of the Viridiplantae—the green plants, consisting of green algae and land plants. The domain is mostly absent in other kingdoms but widely distributed in Viridiplantae. In green algae, a liverwort, and several angiosperms, RWP-RK proteins play essential roles in nitrogen responses and sexual reproduction-associated processes, which are seemingly unrelated phenomena but possibly interdependent in autotrophs. Consistent with related but diversified roles of the RWP-RK proteins in these organisms, the RWP-RK protein family appears to have expanded intensively, but independently, in the algal and land plant lineages. Thus, bryophyte RWP-RK proteins occupy a unique position in the evolutionary process of establishing the RWP-RK protein family. In this review, we summarize current knowledge of the RWP-RK protein family in the Viridiplantae, and discuss the significance of bryophyte RWP-RK proteins in clarifying the relationship between diversification in the RWP-RK protein family and procurement of sophisticated mechanisms for adaptation to the terrestrial environment.
