Images of RNA blotting. Fungal RNA, purified from the wild‐type (WT), the ΔnoxB mutants and the NoxB rescued strain (CpB24) (A), from the ΔnoxR mutants and the NoxR rescued strain (CpR40) (B), from the Δyap1 mutants and the YAP1 rescued strain (CpY) (C), and from the Δhog1 mutants of A. alternata (D), was electrophoresed in a formaldehyde‐containing gel, blotted and hybridized to DNA probes as indicated. Gels staining with ethidium bromide indicate relative loading of the RNA samples. The sizes of the hybridization bands are indicated in kilobase pairs (kb).
