From: Cover crop root exudates impact soil microbiome functional trajectories in agricultural soils
Cover crop exudate treatments influence soil microbial metabolomes. Two-dimensional scores plot of partial least squares discriminate analysis (PLS-DA) (R2X = 0.101, R2Y = 0.0597, Q2 = 0.784, PERMANOVA, p < 0.05) between all treatment metabolomes. Each point represents a metabolome, with colors representing time. Shapes denote treatment: cereal rye (circles), hairy vetch (triangles), sorghum (diamonds), octagons (rapeseed) and control (square) metabolomes. Ellipses represent 95% confidence intervals and are colored by treatment. Corresponding loadings biplot can be found in Additional File 7 Fig 2
