the sigatoka disease complex of banana involves three related ascomycetous fungi viz., mycosphaerella fijiensis, m. musicola, and m. eumusae. due to rather similar symptoms on banana, similar teleomorph morphology and problems associated with growth and sporulation in culture, species identification based on classical methods is troublesome. the exact distribution of these three species and the...

Three species of Mycosphaerella, namely M. eumusae, M. fijiensis, and M. musicola are involved in the Sigatoka disease complex of bananas. Besides these three primary pathogens, several additional species of Mycosphaerella or their anamorphs have been described from Musa. However, very little is known about these taxa, and for the majority of these species no culture or DNA is available for stu...

Yellow and black Sigatoka, caused by Mycosphaerella fijiensis M. musicola, respectively, are the most important worldwide foliar diseases of bananas. Disease control is heavily dependent on intensive fungicide sprays, which increase selection pressure for resistance in pathogen populations. The primary objective this study was to assess level spread quinone-outside inhibitors (QoI—strobilurin) ...

Cladosporium musae, a widespread leaf-spotting hyphomycete on Musa spp., is genetically and morphologically distinct from Cladosporium s. str. (Davidiella anamorphs, Mycosphaerellaceae, Dothideales). DNA sequence data derived from the ITS and LSU gene regions of C. musae isolates show that this species is part of a large group of hyphomycetes in the Chaetothyriales with dematiaceous blastoconid...

This study aimed at the development and validation of an accurate, more affordable, precise digital imaging resazurin-based fungicide sensitivity colorimetric assay (COL-assay) for fungal plant pathogens from genera Mycosphaerella Pyricularia. proposed was based on estimates resazurin reduction, which used as a metabolic indicator respiration activity microplate cultures. As model systems, we y...

Mycosphaerella fijiensis, causal agent of black Sigatoka disease of banana, is a Dothideomycete fungus closely related to fungi that produce polyketides important for plant pathogenicity. We utilized the M. fijiensis genome sequence to predict PKS genes and their gene clusters and make bioinformatics predictions about the types of compounds produced by these clusters. Eight PKS gene clusters we...
