- Regulation of developmental transitions by cytokinin
The role of cytokinin in regulating developmental transitions such as seed germination, juvenile-to adult transition of leaves or the transition to flowering is as yet not well explored. Recently we have shown that cytokinin regulates the juvenile-to-adult transition of leaves through components of the age pathway. Work deciphering the molecular mechanisms of cytokinin action is ongoing. This project is led by Sören Werner. Other projects explore the fine-tuning of seed germination and flowering time by cytokinin (in collaboration with Isabel Bartrina, University of Graz).
The appearance of trichomes is a hallmark of
the juvenile-to-adult transition in Arabidopsis leaves.
