Localization of a Pathogenicity Gene in Ophiostoma novo-ulmi and Evidence That It May Be Introgressed from O. ulmi [PDF]
Molecular Plant-Microbe Interactions, 1999 Ophiostoma novo-ulmi, the principal agent of Dutch elm disease, has recently replaced another species of Dutch elm disease pathogen, O. ulmi, across much of the Northern Hemisphere.

Sequencing and annotation of the Ophiostoma ulmi genome. [PDF]
BMC Genomics, 2013 Abstract Background The ascomycete fungus Ophiostoma ulmi was responsible for the initial pandemic of the massively destructive Dutch elm disease in Europe and North America in early 1910. Dutch elm disease has ravaged the elm tree population globally and is a major threat to the remaining elm population. O.

Duplex real-time PCR assay for the simultaneous detection of Ophiostoma novo-ulmi and Geosmithia spp. in elm wood and insect vectors [PDF]
NeoBiota, 2023 Dutch elm disease (DED) is a destructive tracheomycosis caused by Ophiostoma novo-ulmi, an ascomycete probably originating in East-Asia that is devastating natural elm populations throughout Europe, North America and Asia.

Ophiostoma ulmi DNA naturally introgressed into an isolate of Ophiostoma novo-ulmi is clustered around pathogenicity and mating type loci [PDF]
Phytoprotection, 2019 The invasive fungal pathogensOphiostoma ulmiandO. novo-ulmihave caused two successive pandemics of Dutch elm disease since the beginning of the 20thcentury. In nature, the highly aggressiveO. novo-ulmimay hybridize with the less aggressiveO. ulmi. Growth rate and molecular analyses were conducted on an unusual, moderately aggressiveO. novo-ulmiisolate,

Chromosome-level genome assembly and annotation of Ulmus minor reveal dynamic intrageneric clusters of resistance genes. [PDF]
Plant GenomeAbstract The field elm (Ulmus minor) is an emblematic species of the European landscape, which has been severely affected by Dutch elm disease (DED) since the 20th century. To support restoration and conservation of this species and congeners, we present a de novo assembly and annotation of a wild genotype tested positive for DED resistance, along with

Beech Leaf Disease Associated With Changes in Litter Decomposition and Fungal Communities. [PDF]
Ecol EvolLess than 15 years ago beech leaf disease was identified as a newly emerging forest pest. There is still little known about the larger ecosystem impact. Our study is at the forefront of understanding how this newly emerging disease is impacting leaf litter decomposition and fungal communities in highly infested areas. ABSTRACT Forest pests and diseases
