Spatial scales of interactions among bacteria and between bacteria and the leaf surface. Esser, D. S., Leveau, J. H J, Meyer, K. M., & Wiegand, K. FEMS microbiology ecology, 2015. Pdf doi abstract bibtex Microbial life on plant leaves is characterized by a multitude of interactions between leaf colonizers and their environment. While the existence of many of these interactions has been confirmed, their spatial scale or reach often remained unknown. In this study, we applied spatial point pattern analysis to 244 distribution patterns of Pantoea agglomerans and Pseudomonas syringae on bean leaves. The results showed that bacterial colonizers of leaves interact with their environment at different spatial scales. Interactions among bacteria were often confined to small spatial scales up to 5-20 $μ$m, compared to interactions between bacteria and leaf surface structures such as trichomes which could be observed in excess of 100 $μ$m. Spatial point-pattern analyses prove a comprehensive tool to determine the different spatial scales of bacterial interactions on plant leaves and will help microbiologists to better understand the interplay between these interactions.
