PCA plots of targeted lipidomic analysis (ESI-MS/MS) of P. tricornutum strains. Variate biplots of the first two principal axes derived from a principal component analysis characterising the response of cellular lipids over time of P. tricornutum (WT, Pt_OtElo5, DGAT2B & DGATElo) lines grown in N-replete and N-deplete conditions of the log transformed data are shown. In both panels, points represent the treatment variates and are coloured in either by (a) treatment combinations (strain, time in hours and nitrogen treatment) or (b) lipid group (DGDG, MGDG, SQDG, PC, DGTA, LPC, PE, PI, PG, and TAG). The arrows represent the loadings associated with each principal vector
