Some smut fungi of the family Ustilaginaceae produce itaconate from glucose. De novo genome sequencing of nine itaconate-producing Ustilaginaceae revealed genome sizes between 19 and 25 Mbp. Comparison to the itaconate cluster of U. maydis MB215 revealed all essential genes for itaconate production contributing to metabolic engineering for improving itaconate production.

DNA sequence analysis and genetic mapping of loci from mating-type-specific chromosomes of the smut fungus Microbotryum violaceum demonstrated that the nonrecombining mating-type-specific region in this species comprises approximately 25% ( approximately 1 Mb) of the chromosome length. Divergence between homologous mating-type-linked genes in this region varies between 0 and 8.6%, resembling th...

*Understanding disease distributions is of fundamental and applied importance, yet few studies benefit from integrating broad sampling with ecological and phylogenetic data. Here, anther-smut disease, caused by the fungus Microbotryum, was assessed using herbarium specimens of Silene and allied genera of the Caryophyllaceae. *A total of 42,000 herbarium specimens were examined, and plant geogra...

UNLABELLED Wheat, the major source of vegetable protein in human diet, provides staple food globally for a large proportion of the human population. With higher protein content than other major cereals, wheat has great socio- economic importance. Nonetheless for wheat, three important fungal pathogens i.e. rust, smut and bunt are major cause of significant yield losses throughout the world. Res...

The identity of a neglected smut fungus, Cintractia disciformis, described from Carex hirtella in the Western Himalaya, India is reassessed. The species is excluded from Cintractia and is confirmed as a distinct species of Anthracoidea. Two smuts, A. nepalensis on Carex nakaoana in Nepal, and A. haematostomae on Carex haematostoma in China, are similar morphologically and considered to be later...

We used herbarium specimens of Silene virginica, S. caroliniana, S. rotundifolia, and S. latifolia to survey the incidence of anther-smut disease (caused by Microbotryum violaceum sensu lato) in the eastern USA. We found no evidence of a collector bias against diseased specimens. Diseased specimens were frequently found in collections of S. virginica and S. caroliniana, but not in those of S. r...

Ustiloxins A (1a), B (1b), C (1c), D (1d) and E (1e), antimitotic peptides, have been isolated from the water extract of false smut balls caused on the panicles of rice plant by a fungus Ustilaginoidea virens. The structure of 1b was assigned from its spectral property and its amino acid analysis in relation to 1a whose structure was determined previously by a combination of X-ray crystallograp...

Infection of one host by multiple pathogen genotypes represents an important area of pathogen ecology and evolution that lacks a broad empirical foundation. Multiple infection of Silene latifolia by Microbotryum violaceum was studied under field and greenhouse conditions using the natural polymorphism for mating-type bias as a marker. Field transmission resulted in frequent multiple infection, ...

A case of hypersensitivity pneumonitis caused by a smut fungus Ustilago esculenta is presented.
