AIK1 — Nicotiana attenuata

Summary

A4A49_39823 (AIK1, also known as NPK1) in coyote tobacco (Nicotiana attenuata) encodes a plant MAPKKK family protein with protein serine/threonine kinase activity, MEKK activity, and MAPKK activity. It is associated with diverse molecular functions including ABC-type transporter, auxin efflux, and cadmium ion transmembrane transporter activities. The gene is linked to biological processes such as cytokinesis, regulation of defense response by callose deposition, lateral growth, indole glucosinolate breakdown, and cellular detoxification. It localizes to the cortical microtubule, microtubule organizing center, chloroplast envelope, and endoplasmic reticulum. AIK1 is associated with auxin and jasmonic acid content, leaf senescence, flowering time, seed growth, root morphology and thickness, disease tolerance, and salt tolerance. Phenotypic associations include herbivore resistance, biotic and osmotic stress responses, seed germination, abscisic acid sensitivity, and stomatal response.
