Fig. 6

H. pylori strain G27 was grown as a biofilm or planktonic culture for 3 days, after which RNA was collected and sequenced. A Principal component analysis (PCA) of gene expression obtained by RNA-seq between biofilm growing cells and planktonic ones, with three biological replicates and two technical replicates each for n = 6. B Volcano plot of gene expression data. The y-axis is the negative log10 of P-values (a higher value indicates greater significance) and the x-axis is log2 fold-change or the difference in abundance between two population (positive values represent the upregulated genes in biofilm and negative values represent downregulated genes). The dashed red line shows where P = 0.01, with points above the line having P < 0.01 and points below the line having P > 0.01.
