Plant meristems are responsible for producing all post-embryonic organs during organogenesis. While the shoot apical meristem (SAM) maintains its meristematic property throughout the life of a plant, the floral meristem (FM) undergoes precise processes of initiation, maintenance and termination to ensure proper reproductive development and metagenesis. Plant meristem maintenance and termination are controlled by hierarchical genetic networks. While most of the genes in these networks have specific roles in particular processes, some genes have dual roles in SAM maintenance and FM termination through their interactions with different partners. Here, we summarize the molecular mechanisms of these dual-function regulators important for both SAM maintenance and FM termination and discuss the functions of WOX genes mediated gene regulatory networks on meristem maintenance and termination in different species.
