Biological control of sugarcane smut (Ustilago scitaminea Syd.) using Trichoderma isolates is one the untapped potentials in Ethiopian plantations. To this end, study was carried ...

Peanut smut, caused by the soil-borne pathogen Thecaphora frezii, has increased in incidence main Argentinian peanut-growing regions. Smut-affected pod transform kernel into a mass of teliospores, which survive soil for long time. This study is first large-scale (regional) survey to determine occurrence and distribution peanut smut area Argentina. Surveys were conducted Córdoba province, random...

Extensive genetic studies (1) and limited nutritional investigations (2, 3) have been accomplished for the wheat smut organism, Tilletia caries, but information is lacking concerning its metabolism and enzyme systems. A more systematic approach to control might be realized by a fuller understanding of the nutrition and metabolism of the smut fungus. Studies designed to elucidate the pathway of ...

The smut genus Thecaphora contains plant parasitic microfungi that typically infect very specific plant organs. In this study, we describe a new species of Thecaphora from Oxalis lanata var. rosea (Oxalidaceae) in the Cape Floristic Region of South Africa. Molecular phylogenetic reconstructions based on large subunit ribosomal DNA sequence data confirmed the generic placement of the fungus and ...

Ciboria ploettneriana, Schroeteria decaisneana, and S. poeltii produce morphologically very similar apothecia emerging from fallen stromatized seeds of Veronica spp., the former two on V. hederifolia agg. in temperate central Europe cymbalaria mediterranean southern Europe. They are described illustrated detail based fresh collections or moist chamber cultures infected seeds. A key is provided ...

The bacterial genus Burkholderia is abundant in the sugarcane rhizosphere. Literature states that some Burkholderia strains are nematode and fungal antagonists and/or plant growth promoters. Research was undertaken to obtain indigenous sugarcane-associated Burkholderia strains that possess these properties. Preliminary screening produced 13 isolates that are able to paralyse juveniles of Meloid...

False smut of rice, caused by Ustilaginoidea virens (Cooke) Takahashi (teleomorph: Villosiclava virens), is one of the most important diseases affecting rice worldwide. Agrobacterium tumefaciens-mediated transformation was used to identify functional genes in U. virens. In this study, we selected a single-copy insertion mutant T133 with deficiency in producing conidia by screening the T-DNA ins...

Dioecious plants in the Caryophyllaceae family are susceptible to infection by members of the anthericolous smut fungi. In our studies of the Silene latifolia/Microbotryum lychnidis-dioicae pathosystem, we were interested in characterizing the plant-pathogen interaction at the molecular level before and during teliosporogenesis. This takes place during floral bud development, and we hoped to ca...
