The Remus-Emsermann Laboratory is principally interested how bacterial species grow on plant leaves, which growth pattern they exhibit and how they interact with other species that share the leaf with them. To do so, we mostly rely on fluorescence microscopy techniques such as confocal laser scanning microscopy and widefield epifluorescence microscopy. This in combination with bacteria that are either tagged with fluorescent protein genes, stained using fluorescence in situ hybridisation (FISH), or stained using fluorescent live/dead stains that allow to determine if individual bacterial cells are either alive or dead. To analyse our data we employ image cytometry and spatial statistic tools which allow us to assess pair aggregation patterns of leaf colonising bacteria.
