PP2A — Nicotiana attenuata

Summary

A4A49_36030 (PP2A) in coyote tobacco (Nicotiana attenuata) encodes a serine/threonine-protein phosphatase with a calcineurin-like phosphoesterase domain, annotated with protein serine/threonine phosphatase activity, protein tyrosine phosphatase activator activity, and protein phosphatase regulator activity. It is associated with brassinosteroid signaling, TOR signaling, chloroplast avoidance movement, regulation of abscisic acid anabolism, and downregulation of ethylene-mediated signaling. The gene is linked to numerous agronomic traits including biomass yield, seed yield, leaf elongation rate, root hair length, lateral root length, transpiration rate, iron and cadmium concentration, nitrate sensitivity, phosphorus uptake, and responses to high temperature, osmotic stress, and aluminum. It localizes to the PP2A complex, cytosol, nucleus, mitochondria, and ER membrane. Related genes in other species are linked to phosphorus deficiency tolerance, salinity tolerance, and disease resistance.
