Molecular phylogenetic analyses redefine seven major clades and reveal 22 new generic clades in the fungal family Boletaceae
The results indicated that the characters frequently used in the morphology-based taxonomy of Boletaceae, such as basidiospore ornamentation, the form of the basidioma, and the stuffed pores each had multiple origins within the family, suggesting that the use of such features for high-level classification ofBoletaceae should be de-emphasized and combined with other characters.
Multiple gene genealogies reveal recent dispersion and hybridization in the human pathogenic fungus Cryptococcus neoformans
The analyses indicated that the major lineages in C. neoformans diverged tens of millions of years ago but have undergone recent dispersion and hybridization.
Genomic and Proteomic Analyses of the Fungus Arthrobotrys oligospora Provide Insights into Nematode-Trap Formation
This study will facilitate the identification of pathogenicity-related genes and provide a broad foundation for understanding the molecular and evolutionary mechanisms underlying fungi-nematodes interactions.
One hundred noteworthy boletes from China
M morphological studies and phylogenetic analyses were conducted including species of Boletaceae from China and other parts of the world, indicating that seven subfamily-level major clades and 62 generic clades can be retrieved, 52 of which are found in China.

Both clonal and spontaneous origins of fluconazole resistance in C. albicans are suggested, with little evidence for genotypic clustering according to HIV status or body site.
Molecular mechanisms of nematode-nematophagous microbe interactions: basis for biological control of plant-parasitic nematodes.
Recent advances in the understanding of the interactions between nematodes and nematophagous microorganisms are reviewed, with a focus on the molecular mechanisms by which nematophile microorganisms infect nem atodes and on the nematode defense against pathogenic attacks.
Uniparental Mitochondrial Transmission in Sexual Crosses in Cryptococcus neoformans
Abstract. Restriction fragment length polymorphism (RFLP) in the large ribosomal RNA region of the mitochondrial DNA (mtDNA) was developed as a genetic marker for investigating mitochondrial…

The analyses of gene and genotype frequencies within populations indicated that most loci did not deviate from Hardy–Weinberg equilibrium in most populations and that alleles among loci were in linkage equilibrium in the majority of the local populations, consistent with the hypothesis that sexual reproduction and recombination play an important role in natural populations of this species.
DNA Sequence Analyses Reveal Abundant Diversity, Endemism and Evidence for Asian Origin of the Porcini Mushrooms
DNA sequence variation in three gene markers from samples of these mushrooms from across China revealed fifteen novel phylogenetic species and a newly identified lineage represented by Boletus sp.

No significant difference was found in the patterns of relatedness of strains from the three body sites (oral cavity, vagina, and rectum), regardless of host conditions, indicating dynamic processes of yeast colonization on women.
