CHS — Nicotiana attenuata
Summary
A4A49_34074 (CHS2) in coyote tobacco (Nicotiana attenuata) encodes a chalcone synthase family protein with polyketide synthase type-III domains and exhibits naringenin-chalcone synthase, chalcone isomerase, and tetraketide alpha-pyrone synthase activities. The gene is associated with chalcone and polyketide biosynthesis, flavonoid and anthocyanin metabolism, pigmentation, pistil development, auxin biosynthesis and polar transport, response to gravity and UV light, 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, oxidative stress, UV-B, and root-knot nematodes. Studies of related genes in other species connect the family to pollen exine development, male fertility, sporopollenin biosynthesis, and seed coat pigmentation.
