AP2 — Capsicum annuum

Summary

CaAP2 (T459_05475) on pepper chromosome 2 encodes a floral homeotic APETALA 2 protein with DNA-binding transcription factor activity, transcription corepressor activity, and protein homodimerization activity. It is associated with the regulation of floral organ identity, flower formation, seed development, endosperm development, and starch biosynthesis. The gene is linked to flowering time, floral meristem determinacy, and vegetative phase change, as well as traits including pungency, chilling stress response, salt response, net photosynthetic rate, chlorophyll content, and root morphology. It also connects to lycopene accumulation and biosynthesis, ethylene-responsive gene expression, somatic embryogenesis, photoassimilate translocation, seed yield, and seed mass. Related genes in other species link the family to flower development, seed development, ovule number, and Fusarium wilt resistance.
