PAP1 — Brassica oleracea var. botrytis

Summary

BoPAP1, encoded by gene BOLND125_C05P012180.1_BOLND125_V1 on cauliflower chromosome 5, is a purple acid phosphatase family protein with phosphoenolpyruvate phosphatase, acid phosphatase, and protein phosphatase activities, and binds ferric iron, manganese, and zinc. The gene is associated with pigmentation, regulation of anthocyanin anabolism, anthocyanin anabolism, flavonoid anabolism, regeneration, phloem transport, leaf vascular tissue pattern formation, auxin signaling, brassinosteroid mediated signalling, response to cold, and cellular response to phosphate starvation. It is linked to leaf vein morphology and anthocyanin content traits, and phenotypes including abnormal leaf venation with reduced vein number, and premature senescence with leaf cell death. The protein localizes to the vacuolar lumen, plant-type cell wall, extracellular region, and plasma membrane. Studies of related genes in other species link the family to anthocyanin accumulation, flavonoid and phenylpropanoid biosynthesis, and antioxidant capacity.
