HAP5A — Phaseolus vulgaris

Summary

PHAVU_009G166000, also known as PvHAP5A, PvNF-YC1 or NF-YC4, encodes a protein containing a histone-fold domain and is annotated as a DNA-binding transcription factor and transcriptional co-regulator with chromatin-binding and protein heterodimerization activity. In French bean, this gene is associated with the CCAAT-binding factor complex and localizes to the nucleus, plastid and cytosol. It has been linked to the regulation of photoperiod-sensitive flowering time, microgametogenesis, double fertilization, organogenesis, seed germination, and positive regulation of fatty acid anabolism. Associations with agronomic traits include oleic acid content, seed longevity, leaf number, lateral root number and length, root oxidative activity, temperature stress response, UV-B light sensitivity, auxin and abscisic acid sensitivity, and disease tolerance. Studies of related genes in other species link the NF-YC family to photoperiod-dependent flowering, drought tolerance, freezing stress resistance, pathogen resistance, and seed dormancy.
