Role of a vacuolar iron transporter OsVIT2 in the distribution of iron to rice grains

What is it about?

Rice is a major iron source of dietary intake; however, the molecular mechanisms responsible for loading of Fe to the grains are poorly understood. We found that a node-localized vacuolar iron transporter (VIT2) is involved in distribution of Fe to the grains and that knockout of this gene significantly increased Fe accumulation in the polished rice without yield penalty.
