LHY — triticum aestivum

Summary

TaLHY (TRAESCS7B02G188000) on wheat chromosome 7B encodes a Myb/SANT domain-containing protein with DNA-binding transcription activator activity, RNA polymerase II-specific, and is also annotated with RNA polymerase binding, protein kinase regulator activity, histone H3K9 acetyltransferase activity, and chromatin DNA binding. This gene is associated with circadian rhythm regulation, including temperature compensation, circadian regulation of gene expression, and both up- and downregulation of circadian rhythm. It is linked to photomorphogenesis, flowering time under long-day photoperiods, leaf senescence, anthocyanin metabolism, and responses to UV-C light. Associations with agronomic traits include spot blotch, flag leaf angle, grain iron and zinc content, test weight, photoperiod sensitivity, brassinosteroid content, and starch grain synthesis. Studies of related genes in other species link the family to disrupted circadian rhythms, early flowering, and light signaling.
