Cytokinin (CK) signaling pathways were believed to be restricted to terrestrial plants. However, the identification of CK receptor homologs in phytopathogenic bacteria, cyanobacteria, and early diverging fungi has recently been reported. CK signaling in prokaryotic and non-plant eukaryotic organisms sheds new light on the dissemination and evolution of this hormone.
细胞分裂素(CK)信号通路被认为仅限于陆地植物。然而,最近在植物病原菌、蓝藻和早期分化的真菌中鉴定出 CK 受体同源物。原核生物和非植物真核生物中的 CK 信号转导为该激素的传播和进化提供了新的视角。
