PP2A — Brassica oleracea var. botrytis

Summary

BoPP2A (BOLND125_C06P048220.1_BOLND125_V1) on cauliflower chromosome 6 encodes a protein with protein serine/threonine phosphatase activity, protein tyrosine phosphatase activator activity, cis-trans proline isomerase activity, and DNA-binding transcription factor activity, belonging to the PPA2-like and calcineurin-like phosphoprotein phosphatase families. The gene is associated with regulation of abscisic acid anabolism, auxin polar transport, gibberellin response, sugar-mediated signalling, mitotic spindle organization, and responses to heat, cold, salinity, and bacteria. It is linked to numerous agronomically relevant traits including water use efficiency, flowering time, anthocyanin content, leaf senescence, seed germination and development, seedling growth, root morphology, stomatal opening, and tolerance to cadmium, aluminum, high temperature, and osmotic stress. The encoded protein localizes to the PP2A complex, nucleus, cytosol, cytoplasm, and mitochondria. Related genes in other species connect this gene family to abscisic acid signaling, seed dormancy, drought tolerance, and stress responses.
