13. Genetic Diversity of Isolates of Glomus mosseae from Different Geographic Areas Detected by Vegetative Compatibility Testing and Biochemical and Molecular Analysis
We detected, for the first time, the occurrence of vegetative incompatibility between different isolates of the arbuscular mycorrhizal fungal species Glomus mosseae. Vegetative compatibility tests performed on germlings belonging to the same isolate showed that six geographically different isolates were capable of self-anastomosing, and that the percentage o

14. Genetic Analyses of ENDOTHIA PARASITICA: Linkage Data for Four Single Genes and Three Vegetative Compatibility Types
The loci cre, met and ts segregate independently in Endothia parasitica. The phenotype brown (br) seems to be determined by an allele at or very near the cre locus. The vegetative compatibility types (v-c) 5 and 39 are determined by different alleles at a locus that is not linked to cre, met or ts. Analysis of two crosses of v-c 5 strains by v-c 10 strains p

15. 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

16. Molecular characterization of races and vegetative compatibility groups in Fusarium oxysporum f. sp. vasinfectum.
Restriction fragment length polymorphism (RFLP) and vegetative compatibility analyses were undertaken to assess genetic relationships among 52 isolates of Fusarium oxysporum f. sp. vasinfectum of worldwide origin and representing race A, 3, or 4 on cotton plants. Ten distinct vegetative compatibility groups (VCGs) were obtained, and isolates belonging to dis

17. 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

18. 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

19. Maxillary Sinusitis Caused by Medusoid Form of Schizophyllum commune
We present a case of maxillary sinusitis in a diabetic female caused by the basidiomycete fungus Schizophyllum commune. Identification of the isolate was hampered by its atypical features. Subcultures formed sterile medusoid structures from nonclamped mycelia until spontaneous dikaryotization resulted in the development of characteristic fan-shaped fruiting

20. Genetic Diversity of Fusarium oxysporum Strains from Common Bean Fields in Spain
Fusarium wilt is an endemic disease in El Barco de Avila (Castilla y León, west-central Spain), where high-quality common bean cultivars have been cultured for the last century. We used intergenic spacer (IGS) region polymorphism of ribosomal DNA, electrophoretic karyotype patterns, and vegetative compatibility and pathogenicity analyses to assess the genet

21. Genetics of Vegetative Incompatibility in Cryphonectria parasitica
Vegetative incompatibility in the chestnut blight fungus, Cryphonectria parasitica, in Europe is controlled by six unlinked vic loci, each with two alleles. Four previously identified vic loci (vic1, vic2, vic3, and vic4) were polymorphic in European vegetative compatibility (vc) types. Two new loci, vic6 and vic7, also were identified among European vc type

22. Characterization of Colletotrichum acutatum Causing Anthracnose of Anemone (Anemone coronaria L.)†
Anthracnose, or leaf-curl disease of anemone, caused by Colletotrichum sp., has been reported to occur in Australia, western Europe, and Japan. Symptoms include tissue necrosis, corm rot, leaf crinkles, and characteristic spiral twisting of floral peduncles. Three epidemics of the disease have been recorded in Israel: in 1978, in 1990 to 1993, and in 1996 to

23. Mitotic stability and nuclear inheritance of integrated viral cDNA in engineered hypovirulent strains of the chestnut blight fungus.
Transmissible hypovirulence is a novel form of biological control in which virulence of a fungal pathogen is attenuated by an endogenous RNA virus. The feasibility of engineering hypovirulence was recently demonstrated by transformation of the chestnut blight fungus, Cryphonectria parasitica, with a full-length cDNA copy of a hypovirulence-associated viral R

24. 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
