A11 — Capsicum annuum

Summary

T459_26921 (symbol A11, also known as CHI, TT5, CaCFI) on pepper chromosome 11 encodes a chalcone isomerase (EC 5.5.1.6) with annotated chalcone isomerase, naringenin-chalcone synthase, dihydroflavanol 4-reductase, flavanone 4-reductase, flavanone 3-dioxygenase, and protein binding activities. The gene is associated with flavonoid, anthocyanin, phenylpropanoid, carotenoid, and triterpenoid biosynthesis, as well as responses to UV-B, jasmonic acid, oxidative stress, gravity, and blue light. It is linked to fruit development and ripening, auxin polar transport, and localisation to the cytosol, nucleus, ER, and tonoplast. Associations include fruit color, pungency, anthocyanin content, photosynthetic ability, herbicide sensitivity, drought and salt stress tolerance, and root morphology traits. Related genes in other species are linked to flavonoid production, UV-B sensitivity, seed coat pigmentation, and male fertility.
