CHS — Cucumis sativus

Summary

CsCHS (CSA_4G358690) in cucumber encodes a type III polyketide synthase with chalcone/stilbene synthase domains, annotated with naringenin-chalcone synthase, chalcone isomerase, flavanone 4-reductase, dihydroflavanol 4-reductase, flavonol synthase, trihydroxystilbene synthase, tetraketide alpha-pyrone synthase, acyltransferase, and SUMO transferase activities. The gene is associated with chalcone, polyketide, flavonoid, anthocyanin, and phenylpropanoid biosynthesis, as well as responses to UV-B, gravity, hormones, and auxin polar transport. It localizes to the cytosol, nucleus, ER, and tonoplast. CsCHS is linked to traits including anthocyanin and carotenoid content, photosynthetic and respiration rates, flowering time, root morphology, stomatal opening, and abiotic stress responses such as salt, drought, UV, and oxidative stress tolerance. Phenotypic associations include pollen exine development, male sterility, seed coat pigmentation, and pathogen resistance.
