Advances in Spatial Metabolomics in Medicinal Plants
摘要
Abstract
Mass spectrometry imaging(MSI)is an innovative molecular imaging technique offering significant advantages,including label-free analysis,high molecular coverage,and exceptional sensitivity.MSI has been widely used in studies on the spatial distribution of metabolites in tissues.The continuous advancement of this technique has brought spatial metabolomics,a methodology that integrates MSI with metabolomics.This approach allows for simultaneous localization and imaging analysis of metabolites in tissues across diverse biological samples,encompassing animals,plants,and microorganisms.Recently,spatial metabolomics has demonstrated great potential in medicinal plant research as a crucial technique for precise spatial localization of metabolites in tissues.This review first presents the basic principles and experimental procedures of spatial metabolomics,followed by comparisons of several major MSI techniques,including matrix-assisted laser desorption/ionization mass spectrometry imaging(MALDI-MSI),desorption electrospray ionization mass spectrometry imaging(DESI-MSI),and secondary ion mass spectrometry imaging(SIMS-MSI),where distinctive advantages and limitations of each approach are delineated,as well as key aspects in sample preparation and data processing are addressed.The review subsequently focuses on the applications of spatial metabolomics in medicinal plants,including visualizing the spatial distribution and accumulation pattern of metabolites,clarifying the biosynthesis and transport sites of metabolites,and discovering functional genes associated with biosynthetic pathways in medicinal plants.Finally,this review discusses the current challenges and prospects of spatial metabolomics,aiming to provide a new perspective for investigations in medicinal plant research.关键词
