Lipid accumulation in mycelia of F. graminearum strains. a Lipid accumulation of the indicated strains. Hyphae were stained with Nile red. Photographs were examined under differential interference contrast (DIC) or epifluorescence microscopy. Bar = 10 μm. b Statistical analysis of the number lipid droplets in a. Line bars in each column denote the standard errors of three repeated experiments. The asterisks indicate a significant difference, at P < 0.01. c The concentration of glycerol in hyphae of the indicated strains, respectively. Line bars in each column denote the standard errors of three repeated experiments. The asterisks indicate a significant difference at P < 0.01. d Fatty acids composition in perithecia of indicate strains. Line bars represent standard deviations of total lipid content (n = 3). Asterisks represent significant differences in the total lipid content between wild-type and ΔFgbzip16 mutant (P < 0.01)
