Effect of nitrogen starvation on TAG productivity in transgenic lines of Pt4. This profile shows maximum TAG productivities under nitrogen replete and deplete conditions. Data points on these profiles represent the mean values from three independent studies where in each independent study there were two biological replicates. Error bars were calculated from the standard deviation. EV empty vector, TAG triacylglycerol, WT wild type. Raw data for TAG productivities can be obtained from Additional file 14
