PAP1 — Brassica oleracea var. botrytis

Summary

BoPAP1 (BOLND125_C01P008170.1) on cauliflower chromosome 1 encodes an AUX/IAA family protein with DNA-binding transcription factor activity, SUMO transferase and binding activities, and kinase and identical protein binding. This gene is associated with pigmentation, regulation of anthocyanin and flavonoid biosynthesis, auxin and jasmonic acid signaling, sumoylation, regeneration, shoot apical meristem specification, vascular tissue pattern formation, and responses to cold and abscisic acid. It localises to the cytosol and nucleus. BoPAP1 is linked to anthocyanin accumulation and pigmentation, flavonoid and proanthocyanidin content, flower color, floral volatile production, leaf senescence, osmotic stress tolerance, nematode resistance, root growth, pollen development, and plant growth and development traits including shoot apical meristem identity and embryo development. Related genes in other species are linked to auxin sensitivity, leaf shape, and plant height.
