《"Metabolic and physiological regulation of Chlorella sp.(Trebouxiophyceae, Chlorophyta) under nitrogen deprivation"》
Data are presented as mean±SD（n=3）.Signifi cant diff erence between N+and N-conditions are indicated by asterisks（*P<0.05；**P<0.01）.
To assess the metabolic diff erence at various time points，PCA and OPLS-DA model were used to discriminate the two sample groups（N+and N-）using the fi rst two principal components.Distinct clustering was observed in the data of day 2 and day 4（Fig.4）.The parameters of R 2 X，R 2 Y and Q 2 revealed high discriminative and predictive stability of the model.From over a thousand features aligned in XCMS online，only 59 were selected and annotated using METLIN database based on statistical analysis（P<0.05，fold change>1.5）and their biological roles in Chlorella sp.Overall，the metabolites belonged to several classes，namely amino acids，lipids and fatty acids，nucleic acids，organic acid，phytochemical compounds，vitamins and cofactors.The heat map in Table 2 shows the fold change between N+and N-condition at day 1，2 and 4.The annotated metabolites were classifi ed using the KEGG BRITE mapping tool.
