Relative transcript levels of the hmgR genes of M. circinelloides under aerobic and anaerobic growth conditions. MS12 was cultivated in liquid YNB under continuous light for 4 days at 25°C; transcript level of each gene measured under aerobic growth was taken as 1. The presented values are averages of three independent experiments; error bars indicate standard deviation. Relative transcript values followed by * significantly differed from the value taken as 1 according to the paired t-test (p < 0.01). Light micrographs show the morphology of the fungus growing under aerobic (a) and anaerobic conditions (b) and after 1-h incubation in the presence of oxygen after growing anaerobically for 4 days (c); scale bars indicate 20 μm.
