RT-qPCR expression analysis of the HMGR gene along the growth curve in wild-type and cyp61-mutant strains. The HMGR gene expression in the mutant strains was determined with respect to the control (wild-type strain). A) Strains UCD 67–385, 385-CYP61/cyp61hph and 385-cyp61hph/cyp61zeoB) CBS 6938 and CBS-cyp61hph. C) AVHN2 and Av2-cyp61zeo. Values are the mean ± standard error of three independent experiments.
