Elucidating rhizosphere processes by mass spectrometry - A review.

摘要: The presented review discusses state-of-the-art mass spectrometric methods, which have been developed and applied for investigation of chemical processes in the soil-root interface, so-called rhizosphere. Rhizosphere soil's physical characteristics are to a great extent influenced by complex mixture compounds released from plant roots, i.e. root exudates, high impact on nutrient trace element dynamics interface as well microbial activities or soil physico-chemical characteristics. Chemical characterization accurate quantification present rhizosphere is major prerequisite better understanding requires development application advanced sampling procedures combination with highly selective sensitive analytical techniques. During last years, targeted non-targeted spectrometry-based methods emerged their specific separation various elements wide polarity range successfully several studies. With this we critically discuss work that has conducted within decade context research elemental molecular spectrometry emphasizing different techniques GC, LC CE. Moreover, selected applications such metal detoxification acquisition will be discussed regarding studies exudates plant-bacteria interactions. Additionally, more recent isotope probing technique novel based highlighted.
