PAP1 — Brassica oleracea var. botrytis

Summary

BoPAP1 (BOLND125_C03P049070.1) on cauliflower chromosome 3 encodes an AUX/IAA family protein with DNA-binding, SUMO transferase, SUMO-binding, kinase-binding, homodimerization and protein-binding activities. It is associated with pigmentation, regulation of anthocyanin anabolism, regeneration, embryo shoot apical meristem specification, anthocyanin anabolism, vascular tissue pattern formation, sumoylation, flavonoid anabolism, regulation of translation, JA signaling, auxin signaling, downregulation of transcription, response to auxin, embryo development ending in seed dormancy, response to cold, response to abscisic acid, DNA-dependent transcription, and regulation of DNA-templated transcription. The gene is linked to anthocyanin accumulation, flower color, floral volatile production, leaf senescence, proanthocyanidin content, osmotic stress tolerance, nematode resistance, root growth, pollen development, cytokinin production, chloroplast gene expression, and disease symptom development. Related genes in other species link the family to auxin sensitivity, leaf shape, plant height, seed maturation, and germination rate.
