Fig. 2From: Carbon catabolite repression involves physical interaction of the transcription factor CRE1/CreA and the Tup1–Cyc8 complex in Penicillium oxalicum and Trichoderma reeseiAnalysis of histone methylation patterns and transcription levels of genes in P. oxalicum WT and mutants. A Observation of cellulolytic halo around the colonies, red arrow represents cellulolytic halo. B The transcript abundance of two prominent cellulase encoding genes, Pocbh1 and Poegl1. C Assays of histone methylation patterns using Western blot. Histone H3 was used as the loading control. D The transcript abundance of two histone methyltransferases encoding genes, Poset1 and Poset2. E The transcript abundance of genes Potup1 and Pocyc8. Statistical significance tests were performed by one tailed, unequal variance t-test. *P < 0.05, **P < 0.01, ***P < 0.001Back to article page
