LHY — Phaseolus vulgaris

Summary

PHAVU_010G120401, designated PvLHY (also known as PvCCA1), encodes a Myb/SANT domain-containing protein on French bean chromosome 10. The product possesses DNA-binding transcription activator activity, RNA polymerase II-specific, along with histone H3K9 acetyltransferase activity, protein kinase regulator activity, and chromatin DNA binding. PvLHY is associated with circadian regulation of gene expression, including both upregulation and downregulation of circadian rhythm, temperature compensation of the circadian clock, and starch metabolism. It is linked to negative regulation of leaf senescence, positive regulation of photomorphogenesis and anthocyanin metabolism, and responses to UV-C and gamma radiation. The gene has been connected to numerous agronomic traits including photoperiod-sensitive flowering time, fruit set, leaf area, vegetative vigor, seed viability, root system morphology, cadmium concentration, iron concentration, phosphorus uptake, and responses to aphids, temperature stress, and spot blotch.
