CHS — Solanum tuberosum

Summary

PGSC0003DMG400029620 (CHS1B) on potato chromosome 9 encodes a protein with chalcone/stilbene synthase and polyketide synthase type III domains, and is annotated with naringenin-chalcone synthase, chalcone isomerase, flavanone 4-reductase, flavonol synthase, and SUMO transferase activities. This gene is associated with flavonoid, flavonol, chalcone, and polyketide biosynthesis, pigment accumulation, cell wall thickening, and responses to gravity, UV light, and oxidative stress. It is linked to traits including flower and leaf color, anthocyanin and starch content, photosynthetic and transpiration rates, root morphology, flowering time, and abiotic stress tolerance. The encoded protein localizes to the cytosol, nucleus, endoplasmic reticulum, and tonoplast. Studies of related genes in other species connect the family to pollen exine development, male fertility, sporopollenin biosynthesis, seed coat pigmentation, and disease resistance.
