PHAVU_003G285700 — Phaseolus vulgaris

Summary

PHAVU_003G285700, designated JAI1 (also known as PvMYC2, PvJIN1, and other synonyms) on French bean chromosome 3, encodes a protein of the AIB/MYC-like family with a bHLH domain. The product is annotated with BHLH transcription factor binding, RNA polymerase II cis-regulatory region sequence-specific DNA binding, transcription coactivator and corepressor activities, and additional molecular functions including histidine phosphotransfer kinase and SUMO transferase activities. JAI1 is associated with diverse biological processes: regulation of defense response to insects, drought recovery, positive regulation of seed maturation, trichome spacing, induced systemic resistance via ethylene signaling, chlorophyll metabolism, and cellular responses to sulfur and sulfate starvation. The gene is linked to numerous traits including seed set percent, seed protein content, plant male sterility, fruit ripening, anther length, petal and sepal morphology, branch angle, shoot elongation under submergence, and responses to phosphorus, potassium, and sulfur. Related genes in other species are linked to resistance to bacterial pathogens and herbivory, root architecture, seed oil accumulation, and responses to nutrient deficiencies and abiotic stresses.
