Abstract

Fair exchange Stomata, the gas-exchange structures of plants, are one of the key innovations that allowed plants to conquer the land. Collectively, stomatal activity has a major effect on global carbon and water cycles. So the discovery of the biosynthetic pathway for stomata will be of broad interest. Two groups report the identification of a pathway involving the sequential expression of three closely related genes, SPEECHLESS, MUTE and FAMA. This suggests that consecutive actions of three closely related basic helix–loop–helix proteins control the differentiation of stomata, a mechanism strikingly similar to cell-type differentiation in animals.
