From: Drought and host selection influence bacterial community dynamics in the grass root microbiome
(a) Phylogenetic tree for the 18 grass lineages used in this experiment, constructed from an alignment of three conserved full-length chloroplast gene sequences (rbcL, matK, trnK); nodes for C3 grasses are colored in shades of blue, and C4 grasses are colored in shades of red. (b) The Mantel’s R coefficient is plotted for pairwise comparisons of host phylogenetic distance and microbiome distance for each pairwise combination of sample type, treatment and time point. To maintain sample evenness across the surveyed phylogenetic breadth of host species, C3 and C4 clades were analyzed separately with the inclusion of a single member from the other clade and the outgroup species. The shade of each bar indicates the significance. (c) The Mantel’s R coefficient is plotted for pairwise comparisons of field distance and microbiome distance for each pairwise combination of sample type, treatment and time point. The shade of each bar indicates the significance.
