1. Variabilidade genética do fungo Erythricium salmonicolor, agente causal da rubelose dos citros / Genetic variability of fungus Erythricium salmonicolor, causal agent of pink disease of citrus
The fungus Erythricium salmonicolor is the causal agent of pink disease, which infects branches of many host plants, such as citrus, rubber, and apple. This disease may be a serious problem in Brazil, since it can reduce the citrus production up to 10%. Brazil is the major world citrus producer, therefore this problem is alarming. The genetic diversity of E.

2. Genetic variability in isolates of Colletotrichum lindemuthianum (Glomerella cingulata f. sp. phaseoli)by morfologic markers / Variabilidade genÃtica em isolados de Colletotrichum lindemuthianum (Glomerella cingulata f. sp. phaseoli) por meio de marcadores morfolÃgicos
Colletotrichum lindemuthianum (Glomerela cingulata f. sp. phaseoli) apresenta ampla variabilidade genÃtica, demonstrada por suas caracteristicas morfolÃgicas. Este trabalho objetivou caracterizar, por meio de marcadores morfolÃgicos, diferentes isolados (LV4, LV33, LV47, LV51, LV71, LV76, LV77, LV79, LV80, LV81, LV82, LV83, LV84) de C. lindemuthianum (G.

3. Fumonisin production and other traits of Fusarium moniliforme strains from maize in northeast Mexico.
Strains of Fusarium moniliforme from maize seed collected in four fields in northeast Mexico were tested for fumonisin production in culture, for sexual compatibility, and for vegetative compatibility by using non-nitrate-utilizing mutants. The test results indicate that a diverse population of fumonisin-producing strains of F. moniliforme (Gibberella fujiku

4. Analysis of population structure of the chestnut blight fungus based on vegetative incompatibility genotypes
Vegetative incompatibility is a self/nonself-recognition system in fungi that has often been used for describing phenotypic diversity in fungal populations. A common hypothesis is that vegetative incompatibility polymorphisms are maintained by balancing selection. However, understanding the evolutionary significance of vegetative incompatibility and the fact

5. Functional Analyses of the Neurospora Crassa Mt a-1 Mating Type Polypeptide
The Neurospora crassa mt a-1 gene, encoding the MT a-1 polypeptide, determines a mating type properties: sexual compatibility and vegetative incompatibility with A mating type. We characterized in vivo and in vitro functions of the MT a-1 polypeptide and specific mutant derivatives. MT a-1 polypeptide produced in Escherichia coli bound to specific DNA sequen

6. The Product of the Het-C Heterokaryon Incompatibility Gene of Neurospora Crassa Has Characteristics of a Glycine-Rich Cell Wall Protein
Filamentous fungi are capable of hyphal fusion, but heterokaryon formation between different isolates is controlled by specific loci termed het loci. Heterokaryotic cells formed between strains of different het genotype are rapidly destroyed or strongly inhibited in their growth. In Neurospora crassa, at least 11 loci, including the mating type locus, affect

7. Genetic Variation in Fusarium Section Liseola from No-Till Maize in Argentina†
Strains of Fusarium species belonging to section Liseola cause stalk and ear rot of maize and produce important mycotoxins, such as fumonisins. We isolated two species, Fusarium verticillioides (Gibberella fujikuroi mating population A) and Fusarium proliferatum (G. fujikuroi mating population D) from maize cultivated under no-till conditions at five locatio

8. Allelic Specificity at the Het-C Heterokaryon Incompatibility Locus of Neurospora Crassa Is Determined by a Highly Variable Domain
In filamentous fungi, the ability to form a productive heterokaryon with a genetically dissimilar individual is controlled by specific loci termed het loci. Only strains homozygous for all het loci can establish a heterokaryon. In Neurospora crassa, 11 loci, including the mating-type locus, regulate the capacity to form heterokaryons. An allele of the het-c
