Tutorial: Mass spectrometry in plant science, part 1 – how a quadrupole produces a mass spectrum




            Mass spectrometry (MS) is one of the most widely used analytical techniques in chemistry, and it has wide applications in plant science. A mass spectrum can be used to identify an analyte (an object of analysis, such as a metabolite) by matching its pattern of mass fragments to the entries in a library of reference spectra. Understanding the fundamental principles behind mass spectrometry enables the proper interpretation of spectra and library search results and may assist in the identification of unknown plant metabolites. What follows is an introduction to the principles behind the experimental acquisition of a mass spectrum using an analyzer commonly found in most plant research institutes.

Seminar: Control of recombination and genome engineering in plants

Today, we hosted Prof. Holger Puchta from the Karlsrühe Institute for Technology here at our institute, the Center for Research in Agricultural Genomics. In the video below, he gives us an update on genome engineering in plants.
