LHY — Brachypodium distachyon

Summary

BRADI_5G19380V3, symbol LHY (BdLHY), encodes a protein with SANT/Myb and homeodomain-like domains that binds DNA and cis-regulatory regions. In Brachypodium distachyon, this nuclear protein is associated with regulation of circadian rhythm, gene expression, and DNA-dependent transcription, as well as with green leaf volatile biosynthesis, virus-induced post-transcriptional gene silencing, and carbohydrate metabolism. The gene has been linked to stripe rust and to drought, cold, and abscisic acid-related stress tolerance. Studies of related genes in other species connect the gene family to heading time, anthesis, plant height, spike length, grain number, grain size, grain yield, starch content, chlorophyll content, leaf number, node number, heterosis, and drought tolerance, as well as to biotic and abiotic stress responses.
