Identification of the main maize root endosphere families of field-grown and pot-grown maize. a Principal coordinate analysis of the microbial communities in bulk soil and endosphere in field- and pot-grown maize (experiments I and II). PCoA plots are based on Bray-Curtis dissimilarity indices. b Analysis of the bacterial communities in both experiments at the family level. The first two panels show the mean relative abundance of families (> 0.5% in the root endosphere) in bulk soil and endosphere. The third panel shows the relative abundance of the identified main microbiome families (highly abundant and enriched in both experiments) in the root endosphere. c Overlap of the enriched (P < 0.05) and abundant families (relative abundance > 0.5%) in the root endosphere of experiments I (blue) and II (red) representing the families of the main microbiome. d Heatmap of the enriched (P < 0.05) and abundant families (relative abundance > 0.5%) in the root endosphere of each experiment. Bulk soil and root endosphere samples are presented separately
