PAP2 — Brassica oleracea var. botrytis

Summary

BoPAP2, located on chromosome 8 of cauliflower (Brassica oleracea var. botrytis), encodes a purple acid phosphatase family protein with phosphoenolpyruvate phosphatase and acid phosphatase activities, binding ferric iron, cobalt, manganese, and zinc. The gene is associated with anthocyanin metabolism and pigmentation, as well as the regulation of carbohydrate metabolism, mitochondrial RNA modification, and cellular response to phosphate starvation. It is linked to photosynthetic rate, leaf senescence, abiotic stress tolerance, and pollen development. Related genes in other species are associated with anthocyanin accumulation, plant growth, and seed oil yield. The encoded protein localises to multiple cellular compartments including the mitochondrial envelope, chloroplast envelope, vacuolar lumen, and plant-type cell wall.
