CHS — Phaseolus vulgaris

Summary

PHAVU_002G039232, designated PvCHS, encodes a protein with chalcone/stilbene synthase, polyketide synthase type III, and thiolase-like domains. In French bean (Phaseolus vulgaris) on chromosome 2, the gene is associated with chalcone isomerase, naringenin-chalcone synthase, dihydroflavanol 4-reductase, flavanone 4-reductase, flavonol synthase, acyltransferase, SUMO transferase, and kinase binding activities. It is linked to chalcone, polyketide, flavonoid, anthocyanin, isoflavonoid, and phenylpropanoid biosynthesis, as well as responses to UV, UV-B, gravity, oxidative stress, and heat acclimation. The product localizes to the cytosol, nucleus, endoplasmic reticulum, and tonoplast. Associations include seed coat color, anthocyanin content, drought tolerance, salt stress tolerance, root-knot nematode resistance, flowering time, stomatal opening, and nitrogen recycling. Studies of related genes in other species connect the family to flavonoid production, UV-B sensitivity, and male fertility.
