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.

在植物，细菌，真菌和其他植物中追踪细胞分裂素受体

细胞分裂素（CK）信号通路被认为仅限于陆生植物。然而，最近已经报道了在植物病原性细菌，蓝细菌和早期发散真菌中CK受体同源物的鉴定。CK信号在原核和非植物真核生物中的应用为这种激素的传播和进化提供了新的思路。
