Reinforcement of bioproductivity by uncovering plant iron sensing mechanism

　Plant growth absolutely requires iron. Nevertheless, iron is not sufficiently taken up by plants growing in many problem soils. Under iron deficiency conditions, plants induce expression of various genes to utilize sparingly available iron, although the molecular mechanisms that underlie this response, including iron deficiency signal(s) and iron sensor molecule(s) have yet to be clarified. This research aims to clarify the entity of these molecules to uncover the mechanism of plant iron deficiency response, providing new technology and knowledge towards reinforcement of bioproductivity.
