The stomatal fates: Understanding initiation and enforcement of stomatal cell fate transitions

Curr Opin Plant Biol. 2023 Sep 12:102449. doi: 10.1016/j.pbi.2023.102449. Online ahead of print.ABSTRACTIn the stomatal lineage, repeated arcs of initiation, stem-cell proliferation, and terminal cell fate commitment are displayed on the surface of aerial organs. Over the past two decades, the core transcription and signaling elements that guide cell divisions, patterning, and fate transitions were defined. Here we highlight recent work that extends the core using a variety of cutting-edge techniques in different plant species. New work has discovered transcriptional circuits that initiate and reinforce stomatal fate transitions, while also enabling the lineage to interpret and respond to environmental inputs. Recent developments show that some key stomatal factors are more flexible or potentially even interchangeable, opening up avenues to explore stomatal fates and regulatory networks.PMID:37709566 | DOI:10.1016/j.pbi.2023.102449
