PAP2 — Brassica napus

Summary

BnPAP2 (PAP2) on chromosome C05 encodes a purple acid phosphatase family protein, possessing phosphoenolpyruvate phosphatase, acid phosphatase, and protein phosphatase activities, along with metal-binding properties including ferric iron, manganese, cobalt, and zinc. In oilseed rape, this gene is associated with anthocyanin metabolism and its regulation, petal development, pigmentation, and flower color. It is also linked to mitochondrial RNA modification, mitochondrial outer membrane protein import, and cellular response to phosphate starvation. Associations extend to photosynthetic rate, leaf senescence, abiotic stress tolerance, and pollen development. Related genes in other species are linked to anthocyanin accumulation, plant growth, and seed oil yield.
