AIK1 — Nicotiana attenuata

Summary

A4A49_04522 (AIK1, also known as NPK1) in coyote tobacco (Nicotiana attenuata) encodes a protein with serine/threonine kinase activity, including MAPKK and MEKK activity, and is a member of the plant MAPKKK family. It is associated with multiple cellular processes, including cytokinesis, lateral growth, regulation of defense response by callose deposition, and indole glucosinolate breakdown. The gene has been linked to traits such as auxin content and sensitivity, jasmonic acid content, leaf senescence, root morphology and thickness, seed growth, flowering time, and disease tolerance. It is also connected to phenotypes including herbivore resistance, biotic and osmotic stress responses, salt stress tolerance, abscisic acid sensitivity, stomatal response, and cadmium efflux and tolerance. The protein localizes to structures including the microtubule organizing center, cortical microtubules, chloroplast envelope, and endoplasmic reticulum.
