PAP1 — Nicotiana attenuata

Summary

A4A49_12032 (PAP1) on chromosome 7 of coyote tobacco 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, flavonoid, phenylpropanoid, alkaloid, and nicotine anabolism, pigmentation, 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, anthocyanin and flavonoid content, leaf senescence, pollen development, abiotic stress tolerance, and vascular development. Related genes in other species are linked to phosphate limitation tolerance, anthocyanin pigmentation, phenylpropanoid biosynthesis, and seed oil yield.
