CHS — Cicer arietinum

Summary

LOC101489106 (CaCHS) on chickpea chromosome 6 encodes a protein with chalcone/stilbene synthase and polyketide synthase type-III domains. The gene is annotated with naringenin-chalcone synthase, chalcone isomerase, flavonol synthase, dihydroflavanol 4-reductase, flavanone 4-reductase, biphenyl synthase, and SUMO transferase activities. CaCHS is associated with anthocyanin, flavonol, and proanthocyanidin biosynthesis, phenylpropanoid metabolism, phytoalexin production, and responses to UV light, gravity, and auxin polar transport. It localizes to the cytosol, nucleus, endoplasmic reticulum, and tonoplast. The gene is linked to seed coat color and pigmentation, anthocyanin content, drought tolerance, salt stress tolerance, root morphology, flowering time, amylose and fructose content, parasitic weed response, leaf relative water content, and nematode resistance. Related genes in other species are linked to flavonoid production, UV-B sensitivity, male fertility, and defense responses.
