Pleospora species with Stemphylium anamorphs: a four locus phylogeny resolves new lineages yet does not distinguish among species in the Pleospora herbarum clade
TLDR
A rigorous phylogenetic analysis of the relationships among Stemphylium isolates with particular emphasis on species delimitation in the P. herbarum clade provided strong support for the main groupings obtained earlier and also revealed six possible new species. Expand
Resistance spectra of wheat cultivars and virulence diversity of Magnaporthe grisea isolates in Brazil
TLDR
The wheat cultivar BR18 exhibited a broad resistance spectrum in relation to the rest of the tested cultivars to the isolates of M. grisea, and can be used in wheat resistance breeding. Expand
Severe Outbreak of Stemphylium Leaf Blight, a New Disease of Cotton in Brazil.
TLDR
On the basis of its morphological, cultural, and pathogenic characteristics, the principal pathogen causing leaf blight symptoms was identified as Stemphylium solani, which caused up to 100% yield losses in some commercial fields of cultivar Paraná 3. Expand
Integrated management of major wheat diseases in Brazil: An example for the Southern Cone Region of Latin America
Abstract Wheat is an important crop in the Southern Cone region of Latin America. Some of the common wheat diseases in this region are Xanthomonas streak, spot blotch, tan spot, and leaf blotch andExpand
Clonality and geographic structure of host-specialized populations of Corynespora cassiicola causing emerging target spot epidemics in the southeastern United States
TLDR
The lack of geographic structure of populations on soybean suggests limited dispersal among more established populations of C. cassiicola, or genetic differences in founder populations that colonized different geographic areas. Expand
ERIC and REP-PCR Banding Patterns and Sequence Analysis of the Internal Transcribed Spacer of rDNA of Stemphylium solani Isolates from Cotton
TLDR
The tomato isolate from the State of São Paulo showed a distinct ITS sequence from that of the cotton isolates and tomato isolates from the state of Goiás, giving evidence that it belongs to a different genotype of S. solani. Expand
Genetic diversity among isolates of stemphylium solani from cotton
TLDR
Analise de RAPD demonstrou a presenca de polimorfismo entre os generos e especies, andando os fragmentos amplificados foram digeridos com oito enzimas de restricao, padroes identicos de bandas foram observados para todos os isolados. Expand
Molecular and pathogenic variability of Drechslera isolates from oats
TLDR
The rDNA analysis suggests that Drechslera probably comprises at least three distinct taxa, and indicates that the difference observed between the isolates originating from two types of symptoms is due to intra-specific variants of D. avenae. Expand
A Semi-Selective agar medium to detect the presence of Xanthomonas axonopodis pv. malvacearum in naturally infected cotton seed
TLDR
Os criterios para o meio semi-seletivo foi o mais preciso e confiavel; as caracteristicas tipicas das colonias de Xam e sua patogenicidade em algodoeiro e a recuperacao do patogeno de tecidos homogenizados da folha infetada, foram comparaveis. Expand
Somaclonal variation for disease resistance in wheat and production of dihaploids through wheat x maize hybrids
Seven wheat cultivars having some degree of resistance to Bipolaris sorokiniana, Magnaporthe grisea or Xanthomonas campestris pv. undulosa (Xcu) provided somaclonal variation for disease resistance.Expand
