BHLH — Brachypodium distachyon
Summary
BdBHLH (BRADI_3G53060V3) on Brachypodium distachyon chromosome 3 encodes a basic helix-loop-helix (bHLH) transcription factor with RNA polymerase II-specific DNA-binding and protein dimerization activities. The gene is associated with root hair cell differentiation, initiation, elongation, and tip growth, as well as asymmetric cell division and cell development. It has been linked to regulation of both short-day and long-day photoperiodism, flowering, and secondary shoot formation. Phenotypic associations include root hair development, ABA sensitivity and signaling, phosphorus acquisition, and seed longevity. The protein localizes to the nucleus and mitochondria. Studies of related genes in other species connect the family to root hair density, length, phosphorus uptake, grain weight, plant height, seedling vigor, and panicle length.
