PP2A — Nicotiana attenuata

Summary

A4A49_62455 (PP2A, PP2A2) on chromosome 10 of coyote tobacco (Nicotiana attenuata) encodes a serine/threonine-protein phosphatase with protein tyrosine phosphatase activator activity, protein phosphatase binding and regulator activity, and calcium-dependent protein serine/threonine kinase activity. The gene is associated with brassinosteroid signaling, TOR signaling, chloroplast avoidance movement, regulation of abscisic acid anabolism, and downregulation of ethylene-mediated signaling. It has been linked to numerous agronomic traits including biomass yield, seed yield, leaf elongation rate, root development, cadmium concentration, nitrate sensitivity, phosphorus uptake, aluminum response, osmotic response sensitivity, high temperature stress response, and transpiration rate. The encoded protein localizes to the PP2A complex, cytosol, nucleus, mitochondria, ER membrane, and plasmalemma. Related genes in other species are linked to phosphorus deficiency tolerance, potassium uptake, ethylene signal transduction, salinity tolerance, and disease resistance.
