“…Multivariate analysis of 11 unsaturated FAs, which have been used in the previous study (Imbs et al 2007b), confirmed the distinction between PUFA profiles of 3 representative alcyonarian genera: Lobophytum, Sarcophyton, and Sinularia (Fig. 5).…”

“…Predominance of 16:0, 18:3n-6, and 18:4n-3 in FA of hexacoral zooxanthellae have been previously reported (Al Moghrabi et al 1995, Papina et al 2003, Zhukova & Titlyanov 2003, Treignier et al 2008. The level of 18:3n-6 and 18:4n-3 was very low in azooxanthellate alcyonarians (Imbs et al 2007b), gorgonians (Imbs et al 2009), and hexacorals Balanophyllia sp., Tubastrea aurea (Table S3), T. coccinea, and T. micrantha (Latyshev et al 1991). On the contrary, the level of these acids in zooxanthellate hexacorals ranged from 2 to 15% of total FA (Table S3; Latyshev et al 1991, Imbs et al 2007a).…”

“…Azooxanthellate soft corals lacked 16:2n-7 (Imbs et al 2007b(Imbs et al , 2009; Table S4). The difference in substratum specificity of Δ6 desaturase in zooxanthellae, which convert 18:2n-6 to 18:3n-6 or 16:1n-7 to 16:2n-7, can be accepted as a possible explanation of this correlation.…”

“…The absence of zooxanthellae also correlated with the increase of 7-Me-16:1n-10 content. Probably, 7-Me-16:1n-10 does not characterize the whole bacterial community, but can serve as a biomarker of some specific bacterial groups associated with corals (Imbs et al 2007b).…”

“…In addition, zooxanthellae have an FA composition different from that of external food sources (Bishop & Kenrick 1980, Zhukova & Titlyanov 2003, The transport of FA from zooxanthellae to the host has been documented (Harland et al 1993, Al Moghrabi et al 1995, Ward 1995, Papina et al 2003. Therefore, the absence of symbiotic dinoflagellates in corals should lead to a significant difference in lipid and FA compositions between zooxanthellate and azooxanthellate coral species (Imbs et al 2007b). …”

The lipid class and fatty acid (FA) composition for 93 species of reef-building and soft corals from the South China Sea (Vietnam) were analyzed and statistically compared to study systematic patterns of the distribution of lipids in corals and the influence of zooxanthellae on the lipids of symbiont-host association. The lipid and FA compositions of hexacorals and octocorals significantly correlated with their taxonomic position, but the lipid features of species within each of these systematic groups mainly depended on the presence of zooxanthellae. The hexacorals had lower content of polar lipids (PL), sterols (ST), and monoalkyldiacylglycerols (MADAG), but higher content of triacylglycerols (TG) and wax esters (WE) than the octocorals. On average, zooxanthellate species contained less structural lipids (PL+ ST), but more MADAG when compared to azooxanthellate species. Tetracosapolyenoic acids 24:5n-6 and 24:6n-3 were chemotaxonomic markers for octocorals, whereas 22:5n-6 was a marker for Milleporidae. A strong correlation was apparent between zooxanthellate coral family and/or genus and the content of the unsaturated FA; 12 FAs were significant for the separation of azooxanthellate and zooxanthellate specimens. The latter had lower concentrations of 7-Me-16:1n-10, 18:1n-7, and six C 20 -24 polyunsaturated FA, but higher concentrations of 16:0, 16:2n-7, 18:3n-6, and 18:4n-3. The presence of > 2% of 18:3n-6 and 18:4n-3 of total FA is characteristic of zooxanthellate corals. An inverse correlation was established between the content of 18:3n-6 and 16:2n-7 in zooxanthellate soft corals. The present study highlights the importance of zooxanthellae in coral lipid metabolism, especially when compared with symbiont-host exchanges in reef-building and soft corals.
