PP2A — Brassica oleracea

Summary

BoPP2A, encoded by the cabbage gene BOLC102_C06P048560.1 on chromosome 6, belongs to the PPA2-like family of serine/threonine protein phosphatases and exhibits protein tyrosine phosphatase activator activity, cis-trans proline isomerase activity, and DNA-binding transcription factor activity. The gene is associated with the regulation of abscisic acid anabolism, auxin polar transport, and sugar-mediated signalling, as well as responses to heat, cold, salinity, and bacteria. It has been linked to traits including water use efficiency, anthocyanin content, flowering time, seedling growth, root morphology, leaf senescence, and seed development. Localisation evidence places the product in the PP2A complex, nucleus, cytosol, and mitochondria. Related genes in other species connect the family to abscisic acid sensitivity, seed germination, drought tolerance, and stomatal aperture.
