  • The role of cytokinin in the shoot apical meristem
    Cytokinin regulates size and activity of shoot apical meristems through the WUS/CLV pathway. However, the relevance of meristematic subdomains and the transcriptional regulation of target genes are still to be explored. Recently, we have started a project to identify the role of cytokinin signaling in different domains of the shoot apical meristem. This project is led by Bernadette Eichstädt.

Enhanced cytokinin signaling increases
