AP2 — Brassica napus

Summary

BnAP2 (AP2) on chromosome A01 of oilseed rape encodes a protein with an AP2/ERF DNA-binding domain and exhibits transcription corepressor activity, cis-regulatory region binding, DNA binding, and protein homodimerization activity. It is localized to the nucleus, cytoplasm, and transcription regulator complex. The gene is associated with regulation of seed development, starch biosynthesis, floral organ abscission, seed abscission, upregulation of photosynthesis, chlorophyll metabolism, vitamin A and B6 metabolism, alkane anabolism, sulfur metabolism, organogenesis, shoot regeneration, and cellularization. It has been linked to traits including seed weight, plant height, root morphology, drought tolerance, submergence tolerance, leaf number, protein content, jasmonic acid content, and soluble protein content. Related genes in other species connect the family to floral development, meristem identity, seed yield, and sugar metabolism.
