HAP2A — Phaseolus vulgaris

Summary

PvHAP2A (PHAVU_006G062200) on French bean chromosome 6 encodes a nuclear transcription factor Y subunit A (NF-YA) family protein with a CCAAT-binding factor conserved sequence, and is annotated as a sequence-specific DNA-binding transcriptional co-regulator. It is associated with the CCAAT-binding factor complex, nucleus, cytosol, cytoplasm, plastid, and extracellular regions. The gene is associated with regulation of photomorphogenesis, long-day flowering, seed dormancy and germination, microgametogenesis, organogenesis, meiotic cytokinesis, hyperosmotic salinity response, reactive oxygen species metabolism, and gibberellic acid signaling. It has been linked to traits including photoperiod-sensitive flowering time, seed protein and starch content, plant male sterility, anther and petal morphology, leaf chlorosis, stem elongation, anthocyanin content, root oxidative activity, and responses to high temperature, abscisic acid, and cytokinin. Studies of related genes in other species link the NF-YA family to salinity tolerance, pathogen resistance, flowering time, and root growth.
