A11 — Brassica napus

Summary

BnA11 (A11) on chromosome A07 of oilseed rape (Brassica napus) encodes a chalcone isomerase. The gene product also exhibits naringenin-chalcone synthase, flavanone 4-reductase, dihydroflavanol 4-reductase, and flavanone 3-dioxygenase activities, and is associated with protein binding. It is linked to pigment metabolism, chalcone anabolism, anthocyanin anabolism, proanthocyanidin anabolism, seed development, and responses to UV-B, karrikin, and gravity. Associations include seed color, flavonoid and anthocyanin content, photosynthetic ability, herbicide sensitivity, insect damage response, flower development, abiotic stress tolerance (including salt, drought, low temperature, and nitrogen stress), root morphology, and stomatal closure. The protein localizes to the cytosol, nucleus, endoplasmic reticulum, and tonoplast. Related genes in other species link the family to oxidative stress tolerance, UV-B sensitivity, and seed coat pigmentation.
