CHS — Nicotiana attenuata

Summary

A4A49_08280 (CHS2) on chromosome 1 of coyote tobacco (Nicotiana attenuata) encodes a chalcone synthase family protein with chalcone isomerase, naringenin-chalcone synthase, flavanone 4-reductase, dihydroflavanol 4-reductase, flavonol synthase, acyltransferase, SUMO transferase, and tetraketide alpha-pyrone synthase activities. The gene is associated with chalcone, polyketide, flavonoid, anthocyanin, phenylpropanoid, and auxin biosynthesis, as well as flavonol biosynthesis, pigmentation, pistil development, response to UV and gravity, auxin polar transport, and PTGS. It is linked to flower color, cytoplasmic male sterility, UV light sensitivity, respiration and photosynthetic rates, seed size, anthocyanin content, stomatal opening, flowering time, root morphology, salt and drought tolerance, and oxidative stress response. Studies of related genes in other species connect the family to pollen exine development, male sterility, and pathogen resistance.
