NF-YB7 — Phaseolus vulgaris

Summary

PHAVU_009G155500, designated PvNF-YB7, encodes a DNA-binding transcription activator with RNA polymerase II-specific activity, belonging to the NF-YB/HAP3 transcription factor family and containing a histone-fold domain. In French bean (Phaseolus vulgaris) on chromosome 9, this gene is associated with regulation of flowering time, particularly in response to long-day photoperiods, as well as seed germination, nodulation, stomatal complex development and patterning, photomorphogenesis, and responses to heat, thirst, and ABA and GA signaling. It is linked to traits including leaf chlorosis, starch and seed protein content, shoot apical meristem development, seed dormancy, hypocotyl morphology, root morphology, disease tolerance, and salt tolerance. Related genes in other species are associated with pathogen resistance, disease resistance, and flowering time. The protein localizes to the nucleus, CCAAT-binding factor complex, and RNA polymerase complexes.
