Fig. 4From: Metabolic stress constrains microbial L-cysteine production in Escherichia coli by accelerating transposition through mobile genetic elementsPrincipal component plot of all samples subjected to transcriptome analysis. Later generation populations (LGPs) are marked with filled-in shapes, while shapes of early generation populations (EGPs) are unfilled. LGPs correspond to populations with 60–65 evolved generations, while EGPs correspond to populations with 7–10 evolved generations. Related samples are marked with the same colour. Samples displayed in close proximity indicate very few differences between them while samples placed more distantly suggest bigger variationsBack to article page
