AP2 — Nicotiana attenuata

Summary

A4A49_05123 (AP2) on chromosome 7 of coyote tobacco encodes a protein with an AP2/ERF DNA-binding domain, associated with sequence-specific DNA binding, transcription corepressor and coactivator activity, and blue light photoreceptor activity. This gene is linked to the regulation of seed development, floral organ abscission, nicotine and cytokinin biosynthesis, secondary metabolism, and the photoentrainment of the circadian clock. It localizes to the nucleus, cytosol, and transcription regulator complex. AP2 is associated with traits including seed color, leaf nitrogen content, drought sensitivity, photosynthetic ability, whole plant size, and responses to jasmonic acid, aphids, and insect damage. Related genes in other species are linked to trichome development, mucilage production, and defense against insects and pathogens.
