CHS — Brassica juncea

Summary

BJUB05G42130S, designated BjCHS, encodes a chalcone synthase family protein with chalcone isomerase, naringenin-chalcone synthase, flavanone 4-reductase, dihydroflavanol 4-reductase, flavonol synthase, and SUMO transferase activities. The gene is associated with pigment metabolism, chalcone and flavonol biosynthesis, pigmentation, regulation of anthocyanin and phenylpropanoid metabolism, response to UV and gravity, auxin polar transport, detoxification, and the TCA cycle. It localizes to the cytosol, nucleus, endoplasmic reticulum, tonoplast, and polyketide synthase complex. BjCHS is linked to seed color, flavonoid and anthocyanin content, seed weight, leaf color, root length, flowering time, drought tolerance, salt stress tolerance, photosynthetic rate, chlorophyll content, and heterosis. Related genes in other species are linked to flavonoid production, UV-B sensitivity, male fertility, and defense responses.
