GLK1 — Capsicum annuum

Summary

T459_24857 (GLK1, also known as GLK2, CaGPRI1, CaGPRI2) on pepper chromosome 10 encodes a Myb-domain transcription factor of the GLK1/2-like family that binds sequence-specific DNA and can homodimerize. The gene is associated with regulation of chlorophyll biosynthetic process, pigmentation, carotenoid anabolism, chlorophyll anabolism, the MEP pathway, green leaf volatile biosynthetic process, floral organ senescence, positive regulation of leaf senescence, negative regulation of leaf senescence, upregulation of programmed cell death, cytokinin signaling, and response to hydrogen peroxide. It localises to the nucleus and cytoplasm. Associations include fruit color, carotenoid content, leaf senescence trait, disease tolerance, oxidative stress response, auxin sensitivity, abscisic acid sensitivity, root development trait, seedling growth and development trait, and SALTTL. Studies of related genes in other species link the family to fruit chloroplast development, fruit quality, green shoulder formation, and soluble solid and carotenoid content.
