Plant health is strongly connected with plants´ microbiome; in the case of raw-eaten plants, the microbiome can also have an effect on human health. To study the impact on both subjects, the microbiome composition of seven different Brassica vegetables, each purchased as naturally and industrially processed equivalent, was analyzed. All Brassica vegetables harbored a highly diverse microbiota represented by 10,458 OTUs belonging to 257 bacterial orders. Although 80% of the OTUs were shared by all vegetables, the composition of the microbial community was found to be rather driven by the plant genotype than by the processing pathway. Co-occurrence network analysis indicated a significantly stronger impact of the rare taxa on the community than of the core microbiome. Our results shed light on the microbiome of edible plants and open the door to harnessing the Brassica microbiome for plant disease resistance and human health.
