NAS1 — Cicer arietinum

Summary

CaNAS1 (LOC101510352) on chickpea chromosome 3 encodes a nicotianamine synthase, an enzyme with SAM-dependent methyltransferase superfamily domains that catalyses nicotianamine anabolism. The gene is associated with phloem transport, nitric oxide storage, pollen tube growth and pollen development, as well as response to zinc. Annotated associations include cadmium tolerance, iron translocation, chlorosis, iron deficiency tolerance and rRNA gene expression. Related genes in other species link the gene to iron homeostasis, iron deficiency response, cadmium detoxification, and iron and zinc content. Additional family-level connections include carotene content, leaf chlorosis, zinc sensitivity, salt response and root morphology traits.
