This detailed book aims to address the need for standardizing key steps in plant metabolomics research that is still considered a critical issue in the field. The collection unites diverse mass spectrometry (MS)-based protocols, from sample preparation and extraction of plant primary and secondary metabolites (e.g. a range of sugars, lipids, phytohormones and volatile organic compounds) to metabolite analysis, using exclusively highly sensitive MS-based methodologies, followed by frontline bioinformatics and/or mathematical modeling approaches to produce reliable biological data interpretation. 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, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.
