AP2 — Nicotiana attenuata

Summary

A4A49_42690 (AP2) in coyote tobacco (Nicotiana attenuata) encodes a protein of the AP2/ERF family, possessing DNA-binding, transcription coactivator and corepressor, and blue light photoreceptor activities. The gene is associated with the regulation of seed development, floral organ abscission, and secondary metabolism, including nicotine and cytokinin biosynthesis. It is linked to traits such as seed color, leaf nitrogen content, drought sensitivity, photosynthetic ability, photoperiod-sensitive flowering, and responses to insects, aphids, and jasmonic acid. Associations also include plant male sterility, shoot system elongation, and organ growth. Related genes in other species are linked to trichome development, mucilage production, tannin accumulation, and defense against pathogens and insects.
