System-Wide Adaptations of Desulfovibrio alaskensis G20 to Phosphate-Limited Conditions
Fig 5
The ultrastructure and composition of polar lipids of Dde_3613 (Δagt) and Dde_3661 (ΔolsF).
(A) Representative TEM of the Dde_3613 mutant. Bm marks a representative area filled with bright material. Black arrows point to the inner and outer membranes, p indicates the periplasm. (B) Polar lipid composition of the Dde_3613 mutant grown at different initial phosphate concentrations. (C) Representative TEM of the Dde_3661 mutant. Bm marks a representative area filled with bright material. (D) Polar lipid composition of the Dde_3661 mutant grown at different initial phosphate concentrations. (A) and (C) are shown on the same scale shown by the scale bar in panel (C). Abbreviations for the polar head groups: PE is phosphatidylethanolamine, PG is phosphatidylglycerol, CL is cardiolipin, OL is ornithine lipids, MGDG is monoglycosyl diacylglycerol, GADG is glycuronic acid diacylglycerol. Other lipids include N-acyl-PE and N-acetyl-PE and two unidentified lipids with head group losses of 199 Da and 213 Da.
