CHS — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.3HG0224500 (symbol CHS) on barley chromosome 3H encodes a protein with chalcone/stilbene synthase and polyketide synthase type III domains and a thiolase-like fold. The gene is annotated with naringenin-chalcone synthase activity, biphenyl synthase activity, acyltransferase activity, protein homodimerization activity, and identical protein binding. It is associated with chalcone, polyketide, anthocyanin, phenylpropanoid, flavonoid, and chlorophyll anabolism, as well as pigmentation, pollen wall assembly, and virus-induced post-transcriptional gene silencing. This gene is linked to anthocyanin content and drought tolerance. Related genes in other species, including CHS1, CHSA, CHSE, CHSJ, PKS1, PKS3, and PKS5, connect the family to EC 2.3.1.74.
