P. funiculosum NCIM 1228 TFs expression in response to different carbon substrates. A Bar graph shows the total number of TFs induced in the presence of different carbon substrate used for P. funiculosum cultivation. The TFs having significant expression (> 1 FPKM) and expressed in duplicate samples were identified for all the carbon substrates. B Venn diagram showing the distribution of the TFs expressed across the carbon substrates. C Expression profiles of P. funiculosum NCIM 1228 genes coding for TF cultivated on different carbon substrates. The expression values of the duplicate samples for each carbon substrate were used to plot the heat map. The data for each gene is represented as rows (for gene IDs from top to bottom see Additional file 7), and the carbon substrates used for cultivation are shown as columns. The heat map was divided into 4 clusters according to similarities in expression profiles
