Fig. 5: The sorghum microbiome with drought treatments in the field assay.

a The clustering of microbiome samples using unsupervised UMAP, with colors showing the tissue compartments; b Phylum-level distribution of the sorghum microbiota within drought treatments and tissue compartments. c The numbers of OTUs associated to both plant phenotypes. Colors represent the OTU groups within the same tissue compartments. Inset box indicates OTUs that display either positive (+) or negative (−) correlation for both samples. d Phylum-level distribution of the plant phenotype-associated microbiota within the tissue compartments under drought. e, f The change-point model fitting between OTU abundance and plant phenotypes (e plant dry weight; f plant height) for OTU37122 Arthrobacter strain. Gray dots indicate samples that did not meet the abundance threshold.
