Fig. 4. Effect of incubation after tissue-disruption on the amounts of endogenous volatiles. Volatiles were extracted with methyl tert-butyl ether from intact thalli (lower chromatogram) or from freeze–thaw treated thalli (upper chromatogram), and analyzed using GC–MS. Inset shows the enlarged chromatogram from 15.8 to 18.4 min. C15 sesquiterpenoids with the chemical formulas C15H24 (m/z 204, with peaks k to p) and C15H26O (m/z 222, with the peaks q and r) were tentatively identified based on their MS profiles (Supplemental Fig. S2).
