OR — Daucus carota subsp. sativus

Summary

DCAR_009463, the carrot OR (Or) gene on chromosome 3, encodes a protein with PSase activity and protein-binding capacity, belonging to the Orange-like family. This gene is associated with carotenoid anabolism and upregulation of carotenoid anabolism, chromoplast and chloroplast organization, pigmentation, de-etiolation, protein stabilization, polar cell growth, and response to light stimulus. The product localizes to the plastid, chloroplast membrane, plastoglobule, cytoplasm, and nucleus. Associations include alpha-carotene and provitamin A carotenoid content, carotenoid accumulation and content, plastid development, seed growth and germination, abscisic acid content and biosynthesis, chlorophyll accumulation and biosynthesis, photosynthetic development, salt stress response, and cell elongation. Studies of related genes in other species link the family to chromoplast differentiation, fruit color and development, beta-carotene content and accumulation, thermotolerance, flowering time, and drought tolerance.
