“…In particular, C18-PUFA from plastidic lipids are highly remodeled in response to abiotic stresses; in the cyanobacteria Synechocystis sp. PCC6803, ALA and SDA synthesis is triggered by chilling while in several species from the Chromista kingdom OPA is either increased or redistributed within molecular species (Tasaka et al, 1996;Kotajima et al, 2014;Leblond et al, 2019). As plants, green microalgae display a high amount of -linolenic acid (ALA, 18:3 Δ9,12,15 ) and further the peculiar FA, 16:4 Δ4,7,10,13 which is typical of the Chlorophyta phylum (Lang et al, 2011).…”

“…These two galactolipids are important structural lipids in plastid membranes (Murata and Siegenthaler 1998), and are thus conserved features of virtually every photosynthetic organism. The diversity of MGDG and DGDG forms (as based on the associated fatty acids) in both peridinin-containing dinoflagellates with secondary plastids of red algal origin, and dinoflagellates with aberrant plastids, has recently been reviewed by Leblond et al (2019). Briefly, the peridinin-containing dinoflagellates have been found to segregate into two clusters according to Gray et al (2009b).…”

“…Note that this isolate is cold-adapted and was grown at a lower temperature than the isolates examined in the Gray et al (2009b) study, and that the increased level of unsaturation in 18:5/18:5 DGDG compared to the other type E eyespot dinoflagellates (which were not observed to possess this particular galactolipid) is likely a temperature-induced modulation. In order to provide a graphical representation of the chemotaxonomic relationships (as based on MGDG and DGDG compositions) of the eyespot-and peridinincontaining dinoflagellates (types A-C and E) described above to non-eyespot-containing, peridinin-containing dinoflagellates, all with secondary plastids, a clustergram Leblond et al 2019 and references therein for the use of DMOX derivatives to determine fatty acid double bond positions).…”

“…18 and 20% of galactolipids) that were not observed in appreciable amounts in peridinin-containing dinoflagellates (Gray et al 2009;. These two lipids are also among the major galactolipids in K. mikimotoi at approximately 20 and 9% of galactolipids, respectively (Leblond et al 2019). Both K. brevis and K. mikimotoi were also observed to possess additional 14:0-and 16:0-containing minor species of MGDG and DGDG at lower relative percentages Leblond et al 2019;discussed below).…”
