Fig. 4From: Overexpression of a novel gene (Pt2015) endows the commercial diatom Phaeodactylum tricornutum high lipid content and grazing resistanceMicrographs of the wild type (WT), Pt2015 knockout strain (2015KO), and the Pt2015 overexpression (oeT) strains. Micrographs of the WT (A), 2015KO (B), and oeT (C) strains imaged using differential interference contrast (DIC) optics (all DIC images are shown at the same scale and the scale bar: 5 μm). Scanning electron microscopy (SEM) micrographs of the WT (D), 2015KO (E), and oeT (F) strains. The scale bar is 0.5 μm. Transmission electron microscopy (TEM) micrographs of the WT (G), 2015KO (H), and oeT (I and J) strains. White arrows indicate lipid droplets. The scale bar is 0.5 μmBack to article page
