GGP — Brassica oleracea

Summary

BoGGP (BOLC102_C01P024270.1_BOLC102_V1) on cabbage chromosome 1 encodes a GDPGP family protein with GDP:mannose-1-phosphate guanylyltransferase activity and related guanylyltransferase and phosphorylase activities. The gene is associated with ascorbate metabolism, defence response by callose deposition in cell wall, response to jasmonic acid and heat, and defence response to bacteria. It is linked to numerous phenotypes including vitamin C biosynthesis, ascorbate level, anthocyanin accumulation, non-photochemical quenching, high light acclimation, basal thermotolerance, drought tolerance, pathogen and disease resistance, aphid resistance, pollen fertility, flowering time, leaf senescence, lateral root development, root gravitropism, somatic embryo development, biomass accumulation, photosynthesis, and redox status homeostasis under water stress. The product localises to the nucleus. Studies of related genes in other species link the family to ascorbate biosynthesis and content, disease susceptibility to Alternaria brassicicola, and salt tolerance.
