About this Research Topic
Plants produce metal chelators, such as mugineic acid family phytosiderophores (MAs) and nicotianamine (NA). MAs have been first identified as iron chelators which are secreted by plant roots into the rhizosphere to mobilize low-soluble ferric iron. NA was found as the iron chelator which is involved in iron translocation in plant bodies. However, further research showed that both MAs and NA have the ability to chelate not only iron but also other metal nutrients such as zinc, manganese and copper, and are involved in the homeostasis of these metal nutrients. In addition, it has been shown that manipulation of NA production affects uptake and translocation of the harmful element cadmium. The uptake and translocation of the essential nutrients are regulated by specific transporter proteins. Therefore, the link between the essential nutrients suggests that transport system must overlap.
How elements are interacting with each other during acquisition and translocation is still poorly understood, although its relevancy in determining yield quality and quantity in agriculture. In this Research Topic, we aim to cover essential nutrient homeostasis in plants, including, but not limited to their transport, translocation and interaction with each other. We welcome contributions as Original Research and Review articles.
