Pathway activity changes of S. microadriaticum in response to different growing conditions. a Heatmap of GSVA scores representing the pathway activities calculated based on the expression levels of genes associated with each pathway. The dendrogram on top indicates the hierarchical clustering of samples at the pathway level. Scatter plots demonstrate the correlations of pathway activity changes, denoted by t values, between Spis/Con and Fe/Con (b), P/Con (c), or N/Con (d). The blue line and gray area represent the linear regression line and its 95% confidence interval, respectively
