PAP1 — Nicotiana attenuata

Summary

A4A49_07621 (PAP1, also known as PAP18) in Nicotiana attenuata on chromosome 8 encodes a purple acid phosphatase (PAP) family member with phosphoenolpyruvate phosphatase, acid phosphatase, and protein phosphatase activity, binding ferric iron, manganese, cobalt, and zinc. It is associated with anthocyanin and flavonoid metabolism, pigmentation, phenylpropanoid and alkaloid anabolism, nicotine anabolism, secondary metabolism, detoxification, phloem transport, mitochondrial RNA modification, and chloroplast stroma protein import. The gene has been linked to leaf vein morphology, photosynthetic rate, chlorophyll content, phosphate utilization and starvation responses, anthocyanin biosynthesis, flavonoid content, leaf senescence, pollen development, abiotic stress tolerance, and vascular development. Related genes in other species connect the family to anthocyanin pigmentation, phenylpropanoid biosynthesis, phosphate deprivation responses, and plant growth.
