From: Comparative metabolic profiling of the lipid-producing green microalga Chlorella reveals that nitrogen and carbon metabolic pathways contribute to lipid metabolism

Main nitrogen assimilation related to amino acid metabolism pathway in three Chlorella strains. a glutamate–glutamine system and corresponding transaminase pathways; b protein concentration in three Chlorella strains under N− treatment, all data points in the current and following figures represent the means and SD of five biological replicates (t test, p < 0.05), and the significance of the differences between the 0 day of each strain and other test values in 1, 2, and 6 day in the same strain was tested using a one-way ANOVA. *p < 0.05; c nitrogen assimilation and re-distribution from glutamate. The line plot Y-axis represents median-scaled (ion counts under the curve) intensity data. The intensity data have no units. In all plots, “1.0” represents the median of all the sample values detected for that compound. After determination of the median, any null values are imputed (substituted) with the minimum detected value for that compound
