CHS — Cucumis sativus

Summary

CSA_3G600020 (CHS) in cucumber (Cucumis sativus) on chromosome 3 encodes a protein with chalcone/stilbene synthase and type III polyketide synthase domains, and is annotated with naringenin-chalcone synthase, chalcone isomerase, flavanone 4-reductase, flavonol synthase, and SUMO transferase activities. The gene is associated with flavonoid, anthocyanin, and phenylpropanoid biosynthesis, as well as responses to UV-B, gravity, hormones, and auxin polar transport. It has been linked to traits including anthocyanin and carotenoid content, flowering time, photosynthetic rate, respiration rate, stomatal opening, root morphology, and disease tolerance, with specific connections to powdery mildew resistance, male sterility, pollen exine development, and salt and drought stress tolerance. The protein localizes to the cytosol, nucleus, endoplasmic reticulum, and tonoplast.
