Bondarzewia is a conspicuous and widely distributed mushroom genus, but little is known about its origin and biogeography. Here, we investigated the systematics and biogeography of Bondarzewia species using multi-locus phylogenetic analysis. Four genetic markers, including the internal transcribed spacer (ITS), large nuclear ribosomal RNA subunit (nLSU), elongation factor 1-α (tef1) and mitocho...
This study aimed to identify fungal species associated with trunk diseases of sweet cherries (Prunus avium) in several commercial cherry orchards Beijing, Guizhou and Shandong provinces, China. In total, eighteen strains that fitted well into the concept Diaporthe were isolated. Based on both morphological multi-locus phylogenetic analyses internal transcribed spacer region (ITS), beta-tubulin ...
Eucalyptus trees, mostly native to Australia, are widely planted in the tropics and Southern Hemisphere for the production of wood and pulp. Worldwide surveys of diseases on these trees have yielded a large collection of Ceratocystis isolates from dying trees or from wounds on their stems. The aim of this study was to characterise these isolates and to consider their relatedness to each other. ...
Bidirectional tRNA movement between the nucleus and the cytoplasm serves multiple biological functions. To gain a biochemical understanding of the mechanisms for tRNA subcellular dynamics, we developed in vivo β-importin complex coimmunoprecipitation (co-IP) assays using budding yeast. Our studies provide the first in vivo biochemical evidence that two β-importin family members, Los1 (exportin-...
Molecular characterization of locally isolated Beauveria bassiana (Cordycipitaceae, Hypocreales) strains and their pathogenicity against Ceratitis capitata (Diptera: Tephritidae) adults are herein reported for the first time. Molecular identification based on the phylogenetic analyses of ITS-rDNA and combined data of TEF1 and Bloc, revealed that all fungal strains were conclusively assigned to ...
We developed a novel technique, called pseudouridine site identification sequencing (PSI-seq), for the transcriptome-wide mapping of pseudouridylation sites with single-base resolution from cellular RNAs based on the induced termination of reverse transcription specifically at pseudouridines following CMCT treatment. PSI-seq analysis of RNA samples from S. cerevisiae correctly detected all of t...
Morphological studies and phylogenetic analyses of DNA sequences from three genomic regions - the internal transcribed spacer (ITS) regions of the nuclear ribosomal gene repeat, a partial sequence of RNA polymerase II subunit (rpb2), and a partial sequence of translation elongation factor (tef1) - were used to investigate the systematics of Hypocrea citrina and related species. A neotype specim...
BACKGROUND Species identification is essential for controlling disease, understanding epidemiology, and to guide the implementation of phytosanitary measures against fungi from the genus Diaporthe. Accurate Diaporthe species separation requires using multi-loci phylogenies. However, defining the optimal set of loci that can be used for species identification is still an open problem. METHODS ...
The strong overexpression or complete deletion of a gene gives only limited information about its control over a certain phenotype or pathway. Gene function studies based on these methods are therefore incomplete. To effect facile manipulation of gene expression across a full continuum of possible expression levels, we recently created a library of mutant promoters. Here, we provide the detaile...
Fresh collections, type studies and molecular phylogenetic analyses of a multigene matrix of partial nuSSU-ITS-LSU rDNA, rpb2, tef1 and tub2 sequences were used to evaluate the boundaries of Cucurbitaria in a strict sense and of several related genera of the Cucurbitariaceae. Two species are recognised in Cucurbitaria and 19 in Neocucurbitaria. The monotypic genera Astragalicola, Cucitella, Par...
