Survival of conidia of eight species of Bipolaris, Curvularia, and Exserohilum in soil was compared to identify the species most suitable for use in experiments to assay fungitoxicity of soils amended with animal wastes and agricultural byproducts. Conidia produced on cellulose-containing substrates were added to soil between porous nylon mesh membranes, incubated for 0–12 weeks, retrieved, and...

Mitogen-activated protein kinases (MAPKs) have been demonstrated to be involved in fungal development, sexual reproduction, pathogenicity and/or virulence in many filamentous plant pathogenic fungi, but genes for MAPKs in the fungal cereal pathogen Bipolaris sorokiniana have not been characterized. In this study, orthologues of three MAPK genes (CsSLT2, CsHOG1 and CsFUS3) and one MAPK kinase ki...

ABSTRACT Leaf samples of forage bermudagrass with symptoms of infection by species of Bipolaris, Curvularia, and Exserohilum (dematiaceous hyphomycetes) were collected from three swine waste application sites in Mississippi at eight sampling times during each of 3 years. Samples were assayed for pathogens by observing sporulation on plated leaf tissue. Among 3,600 leaves assayed, eight species ...
