A11 — Cucumis sativus

Summary

CSA_5G505170 (symbol A11, also known as CHI, CsTT5, CsCHI, CsCFI) on cucumber chromosome 5 encodes a chalcone isomerase enzyme (EC 5.5.1.6) with chalcone isomerase activity. This gene is associated with flavonoid, anthocyanin, and proanthocyanidin biosynthesis, as well as pigmentation, fruit development, and responses to UV-B, jasmonic acid, wounding, oxidative stress, and gravity. It has been linked to traits including anthocyanin content, fruit weight and width, exocarp thickness, photosynthetic ability, powdery mildew resistance, drought and salt stress tolerance, and herbicide sensitivity. The gene product localizes to the cytosol, nucleus, endoplasmic reticulum, and tonoplast. Related genes in other species are associated with flavonol content, UV-B sensitivity, oxidative stress tolerance, and genome stability.
