内容記述 |
Cytokinin, a plant hormone, plays essential roles in organ growth and development. The type-B response regulator-mediated cytokinin signaling is repressed by type-A response regulators and is conserved in the liverwort Marchantia polymorpha. Its signal coordinates the development of diverse organs on the thallus body, such as the gemma cup, rhizoid, and air pores. Here we report that the type-B response regulator MpRRB upregulates the expression of the R2R3-MYB transcription factor GEMMA CUP-ASSOCIATED MYB1 (MpGCAM1) in M. polymorpha. Whereas both Mpgcam1 and Mprrb knockout mutants exhibited defects in gemma cup formation, the Mpgcam1 Mprra double mutant, in which cytokinin signaling is activated due to the lack of type-A response regulator, also formed no gemma cups. This suggests that MpGCAM1 functions downstream of cytokinin signaling. Inducible overexpression of MpGCAM1 produced undifferentiated cell clumps on the thalli of both wild-type and Mprrb. However, smaller thalli were formed in Mprrb compared to the wild-type after the cessation of overexpression. These results suggest that cytokinin signaling promotes gemma cup formation and cellular reprogramming through MpGCAM1, while cytokinin signals also participate in activating cell division during thallus development. |
