AP2 — Lactuca sativa
Summary
LsAP2, located on chromosome 4 of garden lettuce (Lactuca sativa), encodes a transcription corepressor with DNA-binding, protein homodimerization, and zinc-binding activities, belonging to the AP2/ERF domain family. It is associated with the regulation of flower development, floral organ identity and abscission, seed development and abscission, starch biosynthesis, gibberellic acid homeostasis, meristem maintenance, and the transition from vegetative to reproductive phase. The gene is linked to traits including flowering time, leaf size, photosynthetic rate, root morphology, jasmonic acid content, lycopene accumulation, fruit ripening, seed yield, and somatic embryogenesis. Related genes in other species are linked to seed development, ovule number, and Fusarium wilt resistance.
