Resumen
The underground world is a lively place, with plant roots, soil microbes, and other undergroundorganisms waging a continual battle for resources. Plant roots take an active role in this conflictthrough the exudation of various chemicals, yet key areas of this process remain mysterious:what genes and gene networks control exudation? How do plant root exudates influence themicrobial community of the soil, and how far does this influence extend from the plant root?Finally, if plant roots do play a large role in soil microbial composition, what effect does plantbiodiversity have on soil microbial biodiversity?Bringing together a combined understanding of root-microbiome interactions is likely toredefine the goals and practices of agricultural management and sustainability. We propose thatmovement of plants into new geographic areas disrupts a tightly co-adapted plant-soilmicrobiome association present in the native environment that contributes to plant health.Although many factors contribute to plant disease, we suggest that the lack of co-adaptationbetween the crop and its soil microbiome is a novel contributing factor that has not beenconsidered in explanations of plant disease epidemics.These and other ideas will be discussed in the presentation.
