Figure 3From: Secretions from the ventral eversible gland of Spodoptera exigua caterpillars activate defense-related genes and induce emission of volatile organic compounds in tomato, Solanum lycopersicumMicrographs of the ventral eversible gland (VEG) of Spodoptera exigua caterpillar. VEG treated with heat (A), Intact VEG – not treated with heat (B), Dead VEG due to heat treatment (ethidium homodimer-1 is well retained in dead VEG cells, producing a bright red fluorescence (C), and Intact VEG polyanionic dye calcein is well retained in live VEG cells, producing an intense uniform green fluorescence (D).
