Differential gene expression in f E. coli (L-1216/2010) with potential to form biofilm versus non-biofilm forming cells of E. coli (L-1339/2013) grown for 72 h. In a, in the volcano plots genes that are represented on the right side of the volcano-axis are up regulated and those that are on left side of the axis are down regulated. In b, cluster analysis of biofilm forming E. coli (L-1216/2010) with non-biofilm forming cells of E. coli (L-1339/2013). In c, heat map analysis shows that the biofilm cells (BF1–BF3) are less related to non-biofilm cells (N1–N3) of E. coli. Principal component analysis (d)
