CHS — Nicotiana attenuata
Summary
A4A49_30006 (CHS, PKSB) in coyote tobacco (Nicotiana attenuata) encodes a type III polyketide synthase with chalcone/stilbene synthase domains, annotated with tetraketide alpha-pyrone synthase, chalcone isomerase, naringenin-chalcone synthase, flavanone 4-reductase, flavonol synthase, and SUMO transferase activities. It is associated with chalcone and polyketide biosynthesis, flavonoid and anthocyanin metabolism, phenylpropanoid biosynthesis, auxin biosynthesis and polar transport, pollen wall assembly, pigmentation, and responses to UV and gravity. The gene is linked to traits including flower color, seed size, anthocyanin content, photosynthetic rate, stomatal opening, flowering time, root morphology, and abiotic stress tolerance, as well as phenotypes such as male sterility, pollen exine development, flavonoid and proanthocyanidin biosynthesis, and drought and salt stress tolerance.
