AP2 — Solanum tuberosum

Summary

StAP2 (PGSC0003DMG400025479) on potato chromosome 2 encodes a DNA-binding transcription factor with transcription corepressor activity, belonging to the AP2/ERF domain family. It is associated with the regulation of floral organ identity, flower formation, and specification of floral organ identity, as well as seed development, abscission, and starch biosynthesis. The gene is linked to flowering time, drought tolerance, photosynthetic rate, starch yield and content, root morphology, and jasmonic acid content. It localises to the nucleus, cytoplasm, and transcription regulator complex, and is associated with responses to biotic stimuli, wound healing, and hormone and carbohydrate anabolism. Related genes in other species link the family to flower and seed development, ovule number, and Fusarium wilt resistance.
