RLKs in anther development. The cell-to-cell communication is essential for specifying different cell types during plant growth, development and adaption to the ever-changing environment. Plant male reproduction, in particular, requires the exquisitely synchronized development of different cell layers within the male tissue, the anther. Receptor-like kinases (RLKs) belong to a large group of kinases localized on the cell surfaces, perceiving extracellular signals and thereafter regulating intracellular processes. Here we update the role of RLKs in early anther development by defining the cell fate and anther patterning, responding to the changing environment and controlling anther carbohydrate metabolism. We provide speculation of the poorly characterized ligands and substrates of these RLKs. The conserved and diversified aspects underlying the function of RLKs in anther development are discussed.
RLKs 在花药发育中的作用。细胞间通讯对于植物生长、发育和适应不断变化的环境过程中指定不同的细胞类型至关重要。植物雄性生殖，特别是需要雄性组织（花药）内不同细胞层的精细同步发育。类受体激酶（RLKs）属于一组位于细胞表面的激酶，能够感知细胞外信号，然后调节细胞内过程。在这里，我们通过定义细胞命运和花药模式形成、响应不断变化的环境以及控制花药碳水化合物代谢，更新了 RLKs 在早期花药发育中的作用。我们对这些 RLKs 的特征不明显的配体和底物进行了推测。讨论了 RLKs 在花药发育中的功能的保守和多样化方面。
