Fig. 3. Metabolites identified in 13C labelling analysis with significant changes in carbon incorporation between crp mutant and WT. Percentage incorporation for each condition was averaged from 2 biological and 3 technical replicates and standard deviations are shown as upward error bars on each fraction of 13C labelling. Two-tailed t-tests were performed between samples of Δcrp/comp. with WT in different time points, and levels of significance for each labelled fraction were expressed as asterisks on the right of corresponding bar (*: p < 0.05; **: p < 0.01; ***: p < 0.001).
