Title: Maintains of a stem cell population to enable branching
Speaker: Prof. Yuling Jiao, Chinese Academy of Sciences.

Host PI: Prof. Rosa Lozano-Duran
Venue: PSC Auditorium
Plants differ from most animals in their retained ability to initiate new cycles of growth and development, which relies on the establishment and activity of branch meristems. In seed plants, branching is achieved by axillary meristems, which are established in the axil of each leaf base and develop into lateral branches. Research into axillary meristem initiation has identified transcription factors and phytohormones as key regulators. Based on these findings, a mechanistic framework for understanding axillary meristem initiation has emerged. In particular, axillary meristems are initiated from a leaf axil meristematic cell population originally detached from the shoot apical meristem. I will discuss mechanisms underlying stem cell fate regulation that enable axillary meristem formation, especially self-renew of the leaf axil stem cell population.
The seminar will be delivered in English.
