Ophiostomatoid fungi associated with conifer-infesting beetles and their phoretic mites in Yunnan, China

MycoKeys, 2017
The Ophiostomatales is an Ascomycete order of fungi that accommodates several tree pathogens and many species that degrade wood. These fungi are commonly vectored by Scolytine bark and ambrosia beetles.

ssRNA bacteriophage metagenomes reveal a diverse set of novel protein families

Protein Science, Volume 35, Issue 5, May 2026.
Abstract The bacteriophages with single‐stranded RNA (ssRNA) genomes (class Leviviricetes) are among the simplest known viruses that encode only three core proteins: a receptor‐binding protein, a capsid protein, and an RNA‐dependent RNA polymerase. The number of isolated ssRNA phages has remained very low, but the accumulating RNA metagenome data have ...

The divorce of Sporothrix and Ophiostoma: solution to a problematic relationship

Studies in Mycology, 2016
One of the causal agents of human sporotrichosis, Sporothrix schenckii, is the type species of the genus Sporothrix. During the course of the last century the asexual morphs of many Ophiostoma spp. have also been treated in Sporothrix. More recently several DNA-based studies have suggested that species of Sporothrix and Ophiostoma converge in what has

Fatal Ophiostoma piceae infection in a patient with acute lymphoblastic leukaemia [PDF]

Journal of Medical Microbiology, 2009
We report to our knowledge the first case of human infection withOphiostoma piceae. ThisSporothrix schenckii-related fungus caused disseminated infection involving the lung and the brain in a patient with lymphoblastic lymphoma. The case emphasizes the significance of molecular techniques for identification of rare fungi in the clinical microbiology ...

Climate Change Projected to Double the Richness and Abundance of Soilborne Phytopathogenic Fungi in Southern Maritime Antarctica

Global Change Biology, Volume 32, Issue 5, May 2026.
We sequenced fungal DNA in barren soils sampled from 12 sites along a 1900‐km transect through sub‐ and Maritime Antarctica and Patagonia. Using LASSO regression, we found air temperature ‐ and notably mean annual air temperature (BIO1) ‐ to be a highly significant predictor for the richness and relative abundance of soilborne plant pathogens.

Functional Expression of the Gene cu, Encoding the Phytotoxic Hydrophobin Cerato-ulmin, Enables Ophiostoma quercus, a Nonpathogen on Elm, to Cause Symptoms of Dutch Elm Disease

Molecular Plant-Microbe Interactions, 2000
We studied the involvement of the phytotoxic hydrophobin cerato-ulmin (CU) in pathogenesis and virulence of Dutch elm disease (DED) by expressing its encoding gene (cu) in Ophiostoma quercus, a nonpathogenic species on elm closely related to the DED ...

Amycelial growth of the fungus Ophiostoma multiannulatum [PDF]

Hereditas, 2009
A method of repeated selection is described. Starting from a wild type strain of Ophiostoma multiannulatum the method consists of a repeated cycle of: selection of certain morphological types, mutagen treatment or backcrossing of the selected types, renewed selection among the survivors or offspring, etc. A sequence of mutants was established, in which

Large shift in symbiont assemblage in the invasive red turpentine beetle.

PLoS ONE, 2013
Changes in symbiont assemblages can affect the success and impact of invasive species, and may provide knowledge regarding the invasion histories of their vectors. Bark beetle symbioses are ideal systems to study changes in symbiont assemblages resulting

FISH Illumination of the Oak Wilt Pathogen, Bretziella fagacearum, on Vectoring Insects and in the Red Oak Host Tissues

Forest Pathology, Volume 56, Issue 2, April 2026.
ABSTRACT Oak wilt, caused by Bretziella fagacearum, is a destructive vascular disease of oaks in North America, yet fine‐scale spatial localisation of the pathogen in host tissues and on insect vectors remains poorly characterised. In this study, we developed and validated a species‐specific fluorescence in situ hybridisation (FISH) probe targeting the
