PP2A — Brassica oleracea

Summary

BoPP2A, encoded by gene BOLC102_C02P031290.1 on cabbage chromosome 2, belongs to the PPA2-like family of serine/threonine protein phosphatases and possesses protein serine/threonine phosphatase activity, protein tyrosine phosphatase activator activity, cis-trans proline isomerase activity, and DNA-binding transcription factor activity. The gene is associated with regulation of abscisic acid anabolism, auxin polar transport, gibberellin response, and sugar-mediated signaling, as well as responses to heat, cold, salinity, and bacteria. It has been linked to traits including iron content, cadmium concentration, phosphorus uptake, water use efficiency, flowering time, seed and seedling development, root morphology, leaf senescence, and anthocyanin content. The encoded protein localizes to the PP2A complex, nucleus, cytosol, and mitochondria. Studies of related genes in other species connect the family to ABA sensitivity, seed germination, stress tolerance, and root development.
