SPEECHLESS duplication in grasses expands potential for environmental regulation of stomatal development.

Abstract excerpt

Plants regulate stomatal development and function to acquire atmospheric carbon dioxide for photosynthesis while minimizing water loss. The ancestral basic helix-loop-helix transcription factor (TF) gene that drove stomata production in early land plants diversified to become paralogs SPEECHLESS (SPCH), MUTE, and FAMA. Extant grasses exhibit a particularly interesting set of duplications and losses of SPCH. Using...
