AP2 — Solanum tuberosum

Summary

StAP2 (PGSC0003DMG400027904) on potato chromosome 9 encodes a protein containing an AP2/ERF DNA-binding domain. It is associated with transcription corepressor and coactivator binding, blue light photoreceptor activity, and protein homodimerization. The gene has been linked to the regulation of starch biosynthesis, seed development and abscission, floral organ abscission, plant epidermal cell fate specification, and responses to biotic stimuli. Associations include traits such as starch yield and content, seed color, branch angle, photoperiod-sensitive flowering, plant male sterility, and responses to aphids, thrips, and jasmonic acid. Localization evidence places the product in the nucleus, cytosol, nucleolus, Cajal body, and SCF complex. Related genes in other species are linked to trichome development, seed mucilage production, and defense against pathogens and insects.
