SPCH — Brachypodium distachyon

Summary

BRADI_3G09670V3 (BdSPCH) encodes a FAMA/SPEECHLESS/MUTE-like basic helix-loop-helix (bHLH) transcription factor that localises to the nucleus and cytoplasm and is associated with DNA-binding transcription activator activity. In Brachypodium distachyon, this gene is associated with stomatal lineage progression, guard mother cell differentiation, guard cell differentiation, and stomatal complex development. It is also linked to seed morphogenesis, seed dormancy, endosperm development, and regulation of abscisic acid anabolism. Associations with osmotic stress response, low humidity response, freezing response, and ABA signaling connect BdSPCH to abiotic stress response. Additionally, the gene has been connected to temperature stress response, leaf senescence, flowering time, disease tolerance, pollen fertility, and seedling growth and development traits. Studies of related genes in other species link the family to cold tolerance, freezing tolerance, and stomatal development.
