PAP1 — Nicotiana attenuata

Summary

A4A49_65254 (PAP1, also known as PAP27) on chromosome 3 of 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 metabolism, pigmentation, phenylpropanoid and alkaloid anabolism, nicotine biosynthesis, secondary metabolism, detoxification, phloem transport, mitochondrial RNA modification, and protein import into mitochondria and chloroplasts. It is linked to leaf vein morphology, photosynthetic rate, chlorophyll content, phosphate utilization and starvation responses, leaf senescence, pollen development, abiotic stress tolerance, and lipid metabolism. Related genes in other species connect the PAP family to phosphate limitation tolerance, anthocyanin accumulation, and seed oil yield.
