CHS — Nicotiana attenuata

Summary

A4A49_39367 (CHS2) in coyote tobacco (Nicotiana attenuata) encodes a chalcone synthase, a type III polyketide synthase with naringenin-chalcone synthase, chalcone isomerase, flavonol synthase, and tetraketide alpha-pyrone synthase activities. The gene is associated with chalcone, polyketide, flavonoid, anthocyanin, and phenylpropanoid biosynthesis, as well as auxin biosynthesis and polar transport, response to UV and gravity, pigmentation, pistil development, and post-transcriptional gene silencing. It has been linked to flower color, anthocyanin content, seed size, stamen morphology, root phototropism, stomatal opening, photosynthetic and respiration rates, flowering time, and responses to abiotic stress, salt, drought, UV-B, oxidative stress, and root-knot nematodes. The protein localizes to the cytosol, nucleus, endoplasmic reticulum, and tonoplast.
