VH1 — Brachypodium distachyon

Summary

BdVH1 (BRADI_3G21400V3) on Brachypodium distachyon chromosome 3 encodes a protein with leucine-rich repeat and serine/threonine kinase domains, characteristic of plant receptor-like kinases. It is annotated with numerous enzyme activities including L-serine-glyoxylate transaminase, caffeate O-methyltransferase, and endo-1,4-beta-xylanase activity. The gene is associated with regulation of body size, anthocyanin metabolism, and glucose transport, as well as traits including seed yield, drought sensitivity, photosynthetic ability, leaf vein morphology, lignin biosynthesis, and herbicide sensitivity. Phenotype associations link it to abscisic acid sensitivity, stomatal development, seed germination, and cuticular wax composition. Studies of related genes in other species connect the family to cotyledon vein patterning, heat tolerance, and biomass accumulation.
