AP2 — Nicotiana attenuata

Summary

A4A49_00099 (AP2) in coyote tobacco (Nicotiana attenuata) encodes a DNA-binding transcription factor containing an AP2/ERF domain and exhibiting transcription corepressor activity, DNA binding, and protein homodimerization. It is localized to the nucleus and cytoplasm. This gene is associated with the regulation of floral organ identity, flower formation, seed development, and abscission, as well as secondary metabolism including nicotine, isoflavonoid, cytokinin, and triterpenoid anabolism. It is linked to starch biosynthesis, organ growth, and the negative regulation of transcription. Associations with agronomic traits include drought sensitivity, photosynthetic rate, chlorophyll content, leaf nitrogen content, sugar content, germination rate, root morphology, and seed yield. Related genes in other species are linked to flowering time, seed development, and flower development.
