PYK — Phaseolus vulgaris

Summary

PHAVU_006G118400, also known as PvPYK, PvHYPK or PvSUF1, encodes a protein containing Huntingtin-interacting K (HINT-K), HYPK_UBA and NAC-like_UBA domains. In French bean (Phaseolus vulgaris) on chromosome 6, this gene is associated with disaccharide transport, sucrose metabolism, fermentation, protein stabilization, upregulation of protein ubiquitination, cell growth, embryo development ending in seed dormancy, salinity response, and response to thirst. It is linked to biomass yield, plant embryo development traits, and phenotypes including suspensor development, endosperm cellularization, globular-stage embryo defects, and dwarf, curled leaves with enhanced immunity. The encoded protein localizes to the NatA complex, plasmodesmata, mitochondria, cytosol, and nucleus. Studies of related genes in other species connect the family to drought tolerance and thermotolerance.
