5">erg20 gene encoding FPP synthase from T. reesei was cloned and functionally analyzed.
The gene overexpressed in T. reesei elevated FPP synthase activity
5">Dolichyl branch of mevalonate pathway was stimulated in the transformants.
In the erg20 overexpressing strains squalene synthase was inhibited.
5">Inhibition of squalene synthase did not affect ergosterol level.
