1. Selection of aggressive pathogenic and solopathogenic strains of Ustilago maydis to improve Huitlacoche production
ABSTRACT Ustilago maydis is a basidiomycete known as the causative agent of 'common smut', worldwide disease of maize that is recognized by the galls it forms, which have considerable potential as a gourmet food. Results of infection are quite variable, even under optimal greenhouse conditions. In order to find pathogenic strains able to be used as a highly

2. Huitlacoche yield in some maize varieties in the Mediterranean region of Turkey
Huitlacoche is the Aztecs name given to the smut galls on ears of maize caused by the pathogenic plant fungus Ustilago maydis [(DC) Corda.)]. It is known as maize mushroom, and it has been considered a delicacy and in Mesoamerica. The aim of the present study was to determine the responses of some maize varieties to the growth of the fungus in order to evalu

3. Evaluation of BC1 and BC2 from the crossing Erianthus arundinaceus with Saccharum for resistance to sugarcane smut caused by Sporisorium scitamineum
Sugarcane smut disease caused by the fungus Sporisorium scitamineum is one of the important fungal diseases affecting sugarcane yield and sucrose content around the world. Cultivar resistance is the most appropriate control method for this disease. In this study, 37 BC1 lines chosen from the crossing YC96-40 (F1 of Erianthus arundinaceus) × CP84-1198 (comme

4. Mating type loci analysis indicates that Villosiclava virens, the casual agent of false smut disease of rice, is a homothallic fungus
Villosiclava virens (anamorph: Ustilaginoidea virens) was isolated from infected rice plants, where it caused false smut. Similar to other ascomycetes, the sexual compatibility of V. virens is controlled by the mating type (MAT) locus. In this study, we applied a PCR-based approach to screen mating type genes in the single asexual spore isolate. Our results

5. Two new records of smut fungi for Panama and new combinations into the genus Tolyposporium
Two species of smut fungi (Basidiomycota) are reported here for the first time for Panama. Narasimhania alismatis (Doassansiales) was found on Sagittaria guayanensis and Tolyposporium kuwanoanum (Ustilaginales) on Cyperus tenuis, a new species of host plant. The name of the latter fungus is a new combination based on the currently accepted name Ustanciospori

6. Diversidade genética de isolados do fungo Sporisorium scitamineum analisada através de fingerprinting da região telomérica / Genetic diversity of isolates of the fungus Sporisorium scitamineum analyzed by fingerprinting the telomeric region
The genetic diversity of Sporisorium scitamineum, the sugarcane smut agent, was characterized in a 14 isolates collection. The isolates were obtained from various sugarcane growing areas and RFLP of the telomeric region was used as molecular marker, compared with AFLP. Teliospores were collected from the whip of infected plants. Teliospores are diploids and

7. Physiological changes in wheat during development of loose smut
This study was planned to determine the dynamics of total phenolic content, polyphenol oxidase and peroxidase activities in wheat (var. Inqlab-91) infected with Ustilago tritici with the objective to investigate the role of phenolics and related enzymes in host pathogen interaction. The biochemical analysis was carried out twice, once at grain filling stage

9. Pathogenic variability of Puccinia melanocephala and Ustilago scitaminea in the State of São Paulo / Variabilidade patogênica de Puccinia melanocephala e Ustilago scitaminea no estado de São Paulo
Rust and smut are among the most important diseases of sugarcane, being considered in every breeding program both in parent selection as well as in evaluating progeny behavior. When the crop is distributed to large extensions, it becomes very important to know the amplitude of the pathogenic variation in the population of the causal agent. Considering the im
