GC-MS analysis of sesquiterpene products of the in vivo expression of HaCS in S. cerevisiae. Diagrams show products obtained by the expression of HaCS and thioredoxin-HaCS in comparison to pESC-Leu2d empty vector (negative control). Peak numbers in each panel correspond to numbers above peaks in the chromatogram. Mass spectra of identified products are shown in the top of each panel with a mass spectrum of an authentic standard below. One of the two main products was identified as δ-cadinene; the fragmentation pattern of peak 7 showed high similarities to γ-cadinene but differed slightly in the retention time. RI: retention indice. I: farnesol.
