NAS1 — Cicer arietinum

Summary

CaNAS1 (LOC101513314) on chickpea chromosome 1 encodes a nicotianamine synthase, a member of the SAM-dependent methyltransferase superfamily with nicotianamine synthase activity. This gene is associated with nicotianamine biosynthesis, phloem transport, nitric oxide storage, pollen tube growth, pollen development, and response to zinc. It has been linked to cadmium tolerance, iron translocation, chlorosis, iron deficiency tolerance, and rRNA gene expression. Related genes in other species are associated with iron homeostasis, iron deficiency response, cadmium detoxification, and iron and zinc content traits, as well as carotene content, leaf chlorosis, zinc sensitivity, and salt response. The gene is also linked to chlorotic leaves, altered metal content, and sterility in tobacco.
