Host identity determines plant associated resistomes

Abstract

Plant microbiome, as the second genome of plant, and the interface between human and environmental microbiome, represents a potential pathway of human exposure to environmental pathogens and resistomes. However, the impact of host identity on the profile of resistomes in plant phyllosphere is unclear and this knowledge is vital for establishing a framework to evaluate the dissemination of antibiotic resistance via the plant microbiome. Here, we explored the phyllosphere microbiome and resistomes in 12 selected plant species. By using High-throughput quantitative PCR, we identified a total of 172 unique resistance genes in plant phyllosphere microbiome, which was significantly divergent from ..
