GLK1 — Capsicum annuum

Summary

Pepper gene T459_20223 (GLK1) on chromosome 7 encodes a MYB-domain transcription factor with sequence-specific DNA binding and protein homodimerization activity. GLK1 is associated with regulation of chlorophyll biosynthetic process, carotenoid anabolism, chlorophyll anabolism, the MEP pathway, positive regulation of leaf senescence, negative regulation of leaf senescence, floral organ senescence, green leaf volatile biosynthetic process, cytokinin signaling, response to hydrogen peroxide, and lateral root development. The gene is linked to fruit color, carotenoid content, chloroplast development, leaf senescence, seedling growth and development, root development, anther morphology, stem senescence, auxin sensitivity, abscisic acid sensitivity, oxidative stress response, and disease tolerance. Related genes in other species are linked to fruit chloroplast development, fruit quality, and green shoulder formation.
