Fig. 5

Abundance of relative % values of upregulated and downregulated bioactive metabolites in P. kessleri-I–P. indica co-culture. Bioactive compounds screened from co-cultured metabolome are depicted in heatmap with respect to the Abundance value of P. kessleri-I and P. indica controls. Ranges of colors are specified as follows: − 10 to − 0.1 as Red, 0.09 to 0.1 as Black and 0.51 to 10 as Green. Heatmap was generated using gplots of R script. Heatmap was used to visualize the comparative relative increase in the abundance value of induced metabolites with respect to Pk-I and Pi controls thus making it easy for visualizing the comparison
