This detailed volume focuses on iron homeostasis in plants, iron being an essential micronutrient that serves as a cofactor in numerous metabolic processes but is harmful in excess. Specifically, the content ranges from protocols to study the iron deficiency response, the interaction between root and microbes under iron deficient conditions, the transcriptional network of iron homeostasis, systemic signaling of iron, chloroplast iron regulation, as well as methods on quantitative proteomics, histochemical iron staining, metal imaging using x-ray fluorescence microscopy, and more. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step and readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Plant Iron Homeostasis: Methods and Protocols serves as a valuable resource for the plant iron homeostasis research community and will be of broad interest to plant biologists, soil scientists, and molecular biologists.
