LHY — Phaseolus vulgaris

Summary

PHAVU_009G259400, designated PvLHY, encodes a protein with DNA-binding transcription activator activity, RNA polymerase II-specific, and is also annotated with protein kinase regulator activity, histone H3K9 acetyltransferase activity, and phosphorelay response regulator activity. This French bean gene on chromosome 9 is associated with circadian regulation of gene expression, upregulation and downregulation of circadian rhythm, and temperature compensation of the circadian clock. PvLHY is linked to starch metabolism, positive regulation of anthocyanin metabolism, positive regulation of photomorphogenesis, negative regulation of leaf senescence, and response to UV-C and gamma radiation. The gene is associated with photoperiod-sensitive flowering time, fruit set, leaf area, vegetative vigor, root system morphology, seed viability, cadmium and iron concentration, phosphorus uptake, and aphid response, temperature stress response, and spot blotch traits. Related genes in other species link the family to photoperiod-dependent flowering, biomass, drought escape, and aphid resistance.
