PMIT1 — Triticum aestivum

Summary

TRAESCS7D02G451900, designated TaPMIT1 on bread wheat chromosome 7D, encodes a member of the NRAMP family with annotated molecular functions including metal ion, manganese ion, iron channel and aluminium ion transporter activities. The gene is associated with the transport and homeostasis of multiple metals, including manganese, iron, cadmium and aluminium, as well as with phytochelatin and phenylpropanoid anabolism, sucrose and lipid metabolism, detoxification and cell death. TaPMIT1 is linked to agronomically important traits such as grain weight, grain width and length, seed weight, starch content, heading time, tiller number, plant height, root fresh weight and volume, chlorophyll content, drought tolerance and grain yield. The protein localises to the membrane and plasmalemma. Related genes in other species are linked to cadmium accumulation.
