PAP1 — Nicotiana attenuata

Summary

A4A49_25263 (PAP1/PAP2) in coyote tobacco (Nicotiana attenuata) encodes a purple acid phosphatase (PAP) family protein with phosphoenolpyruvate phosphatase, acid phosphatase, and protein phosphatase activities, and binds ferric iron, manganese, cobalt, and zinc. The gene is associated with anthocyanin and flavonoid biosynthesis, pigmentation, phenylpropanoid and alkaloid metabolism, nicotine anabolism, and regulation of carbohydrate metabolism. It is linked to phloem transport, mitochondrial outer membrane protein import, and chloroplast stroma protein import. Associations include leaf vein morphology, photosynthetic rate, chlorophyll content, phosphate utilization and starvation response, leaf senescence, pollen development, abiotic stress tolerance, and lipid metabolism. Related genes in other species are associated with anthocyanin pigmentation, phosphate deficiency tolerance, and seed oil yield.
