Inter-compartmental lipid involvement. Principal components analysis (PCA) of fatty acid (FA) moieties in individual lipid species within and across multiple compartments of the Euphyllia glabrescens-Symbiodinium endosymbiosis. (A) host gastrodermal cells (“Host,” hollow squares) versus lipid bodies (“LBs,” solid circles) (B) host (hollow squares) versus in hospite Symbiodinium (“Sym,” gray triangles) (C) LBs (solid circles) versus Sym (gray triangles) across the diel cycle (1: sunrise, 2: noon, 3: sunset, and 4: midnight). T: TAGs, F: FFAs, P: PLs, and S: SEs (see main text for full names of these lipids). The red dash circles presented to cluster the closely related of lipid species and strongly similarity of FA moieties after pairwise comparison of PCA across multiple compartments.
