Repression of rhamnosidase genes in the presence of rhamnose supplemented with different carbon sources. Northern blot analysis of the expression of the rhaA and rhaE genes in the creA^d30 strain growing in the presence of rhamnose (R) and different carbon sources. Pregrown mycelia were transferred to inducing medium (1% w/v rhamnose; R) either with or without an equimolar amount of another carbon source and harvested after 3 h of incubation. G¹ glucose 1% w/v, G^0.15 glucose 0.15% w/v. rRNA is shown as a loading control.
