Figure 2From: Whole-genome resequencing of Escherichia coli K-12 MG1655 undergoing short-term laboratory evolution in lactate minimal media reveals flexible selection of adaptive mutationsFrequency of mutations. The main graph shows the number of endpoint strains in which a specific gene was mutated out of the 11 adaptive endpoints. The smaller graph shows the number of endpoint strains that have acquired a mutation in at least one gene of a general category, such as metabolism or the cell envelope. The bar color of specific genes in the main graph corresponds to the gene's category classification in the smaller graph.Back to article page
