This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"Plants are shaped by the many microbes they host. But scientists are only beginning to understand how, especially in underexplored plant structures like aerial roots. A new study shows that the mucilage secreted by these roots can create a microbiome unlike that found in underground roots and nurture an environment that caters to beneficial, nitrogen-fixing bacteria. Researchers made these discoveries by examining the aerial roots of pink lady shrubs—a fast-growing invasive plant. Metabolite profiling of aerial root mucilage revealed a rich cocktail of nutrients that would be expected to support an equally rich variety of microbes. But genomic analyses suggested a mucilage community dominated by nitrogen-fixing diazotrophs. This homogeneous community structure was linked to the presence of the fungus C. raphigera. The antibacterial activity of this fungus was such that only diazotrophs were allowed to thrive, to the benefit of the pink lady shrubs..."
