Production of stomata, the gas-exchange structure in plants, requires asymmetric cell division and cell type differentiation in an orderly manner. Identification of a key switch gene for the fate transition of stomatal precursor cells revealed a compelling view that consecutive actions of three closely related bHLH proteins control stomatal differentiation, a mechanism strikingly similar to cell-type differentiation in animals.
