FIG. 2.

Northern analysis of ldh transcript accumulation after glycerol-peptone-grown R. oryzae was transferred to media containing new carbon sources and incubated for 5.5 h. Lane 1, glucose; lane 2, xylose; lane 3, trehalose; lane 4, peptone; lane 5, glycerol; lane 6, ethanol; lane 7, lactate; lane 8, glycerol-peptone. The gel used for transfer to the membrane is shown at the bottom. The locations of molecular weight standards (in kilobases) are indicated on the left. Due to the similarity of ldhA and ldhB, the labeled ldhA riboprobe detected both transcripts.
