Two Novel Transcriptional Regulators Are Essential for Infection-related Morphogenesis and Pathogenicity of the Rice Blast Fungus Magnaporthe oryzae
Figure 2
The Δmosom1, Δmocdtf1 and Δmosom1Δmocdtf1 mutants are nonpathogenic.
(A) Barley and rice segments inoculated with the mycelia from the wild-type strain Guy11, YX-145, SK27 (Δmosom1), ES16 (ectopic transformant), SC1 (Δmosom1+MoSOM1), CTK15 (Δmocdtf1), CTC1 (Δmocdtf1+MoCDTF1) and D-3 (Δmosom1Δmocdtf1). a = unwounded leaf and b = abraded leaf. (B) Root infection assays. The mutants SK27 and D-3 were non-pathogenic when inoculated onto rice roots, but the mutant CTK15 was still able to cause some disease symptom. Arrows indicate necrotic lesions. H2O was used as the control. Photographs were taken at 5 days after inoculation.
