Comparison of gene content and organization of the two terpenoid biosynthesis clusters identified in different members of Ceratocystidaceae. One of these clusters (A) contained genes needed for ergosterol biosynthesis. The other contained a gene encoding geranylgeranyl pyrophosphate synthetase (B) which may be involved in protein prenylation or potentially in the production of carotenoids or antimicrobial diterpenes (Keller et al., 2005). The direction and relative size of genes are indicated by arrows. The function of putative synthetic genes is shown by different patterns. Each color/pattern represents a specific gene.
