CHS — Phaseolus vulgaris

Summary

PHAVU_002G038600 (PvCHS) on chromosome 2 of French bean encodes a chalcone synthase family protein with chalcone isomerase, naringenin-chalcone synthase, dihydroflavanol 4-reductase, flavanone 4-reductase, flavonol synthase, acyltransferase, SUMO transferase, and kinase binding activities. The gene is associated with chalcone, polyketide, flavonoid, isoflavonoid, anthocyanin, and phenylpropanoid biosynthesis, as well as response to UV-B, oxidative stress, gravity, heat acclimation, auxin polar transport, and sumoylation. It has been linked to seed coat color and pigmentation, anthocyanin content, drought tolerance, salt and nitrogen stress tolerance, root-knot nematode resistance, root morphology, flowering time, stomatal opening, and plant growth and development traits. The protein localizes to the cytosol, nucleus, endoplasmic reticulum, and tonoplast. Studies of related genes in other species connect the family to flavonoid production, UV-B sensitivity, male fertility, and pathogen response.
