Floral organs are properly developed on the basis of timed floral meristem (FM) termination in Arabidopsis. In this process, two known regulatory pathways are involved. The WUSCHEL (WUS)-CLAVATA3 (CLV3) feedback loop is vital for the spatial establishment and maintenance of the FM, while AGAMOUS (AG...
