PAP1 — Brassica oleracea var. botrytis

Summary

BoPAP1 (BOLND125_C05P058550.1) on cauliflower chromosome 5 encodes an AUX/IAA family protein with DNA-binding, SUMO transferase, SUMO-binding, kinase-binding, homodimerization and protein-binding activities. It is associated with auxin and jasmonic acid signaling, pigmentation, regulation of anthocyanin anabolism, regeneration, embryo shoot apical meristem specification, vascular tissue pattern formation, sumoylation, flavonoid anabolism, regulation of translation, and responses to cold and abscisic acid. The gene is linked to anthocyanin accumulation, flower colour, floral volatile production, leaf senescence, proanthocyanidin content, radical scavenging activity, osmotic stress tolerance, nematode resistance, root growth, pollen development, cytokinin production, chloroplast gene expression, and disease symptom development. Related genes in other species connect the family to auxin sensitivity, leaf shape, plant height, seed maturation, and germination rate.
