A timing mechanism for stem cell maintenance and differentiation in the Arabidopsis floral meristem.

Genes & development - 1 Aug 2009

Sun Bo, Xu Yifeng, Ng Kian-Hong, Ito Toshiro

Abstract excerpt

Developmental regulation of the floral meristem ensures that plants of the same species have similarly sized flowers with a fixed number of floral organs. The maintenance of stem cells in the floral meristem is terminated after the production of a fixed number of floral organ primordia. Precise repression of the Arabidopsis thaliana homeobox gene WUSCHEL (WUS) by the floral homeotic protein AGAMOUS (AG) plays a...
