Nitrogenous metabolite composition and labeling rate in P. tricornutum grown on nitrate and urea sources. a Cellular composition of nitrogenous metabolites expressed as a percentage of the total for the metabolites shown. Metabolites are grouped according to biosynthetic pathways. Data represent the average of four samples taken across the labeling period and are overlaid with individual data points. b 15N-labeling rate, as the percentage of the metabolite pool that becomes labeled per hour calculated from the 3 h measurement. Source data are provided as a Source Data file
