Plant Pathology, 2002
The Dutch elm disease pathogen Ophiostoma novo-ulmi is separated into subspecies novo-ulmi, formerly known as the Eurasian (EAN) race, and subspecies americana, formerly known as the North American (NAN) race. Both subspecies occur in Europe, and hybrids between them are suspected to have emerged in parts of Europe where their ranges overlap ...

Regulated gene silencing in the fungal pathogen Ophiostoma novo-ulmi
Physiological and Molecular Plant Pathology, 2013Abstract Ophiostoma novo-ulmi is the third most devastating fungal pathogen in Canada, affecting native Ulmus spp. Control efforts are pursuing a gene regulation approach, using RNAi cassettes driven by constitutive heterologous promoters to evaluate virulence-related genes. A homologous carbon-catabolite regulated promoter (alcA) was developed for a

The effect of temperature on the growth of the phytopathogenic fungus Ophiostoma novo-ulmi
2022Dutch elm disease (DED), which is caused by the aggressive ascomycete fungus Ophiostoma novo-ulmi, has led to the drying and decay of many elm trees (Ulmus spp.) across Europe, North America, and Central Asia. This phytopathogen is responsible for the second, current DED pandemic, while the less aggressive fungus Ophiostoma ulmi caused the first DED ...

Potential diversity in vegetative compatibility types of Ophiostoma novo-ulmi in North America
Mycologia, 1997The diversity of vegetative compatibility (vc) types of the Dutch elm disease fungus, Ophiostoma novo-ulmi, in North America was recently shown to be very low compared to populations in Europe (Brasier, 1996, Mycologia 88:951-964). To determine if low diversity was caused by a lack of polymorphism at vegetative incompatibility (vic) loci, we made ...

Purification and Partial Characterization of the Extracellular Laccase from Ophiostoma novo-ulmi
Current Microbiology, 1997Ophiostoma ulmi and O. novo-ulmi, both causative agents of Dutch elm disease, can be differentiated by their potential to produce constitutive extracellular laccase. The enzyme has been purified from the culture filtrate to apparent electrophoretic homogeneity and has been partially characterized.

Metabolic distinction of Ulmus minor xylem tissues after inoculation with Ophiostoma novo-ulmi
Phytochemistry, 2005Dutch elm disease (DED) is the most devastating and widespread disease of elms. The pathogen, Ophiostoma novo-ulmi, spreads systemically causing xylem vessels blocking and cavitation, and ultimately resulting in the development of a wilt syndrome. Twig samples from susceptible and resistant Ulmus minor trees were harvested at 0, 5, 15, 30, 60, and 120 ...

Variation among Italian and French elm clones in their response to Ophiostoma novo‐ulmi inoculation
Forest Pathology, 2005SummaryIn 1995 a clone bank of elms from across Italy was created at Antella (Florence, I) under a European Union project. In 1998 an experimental planting of some clones from this source was established in Antella together with material from a similar clone bank in France and two reference clones: Commelin (relatively susceptible) and Lobel ...

Fungal Genetics and Biology, 2010
The fungal pathogen, Ophiostomo novo-ulmi, has been responsible for the rapid decline of American elm (Ulmus americana) across North America and remains a serious threat to surviving elm populations. The production of pectinolytic polygalacturonase enzymes has been implicated as a virulence factor for many fungal pathogens, including O.

Variability of sporulation of the phytopathogenic fungus Ophiostoma novo-ulmi
Zbornik sažetaka 14. međunarodnog simpozija Kopački rit, Jučer, danas, sutraHolandska bolest brijesta biljna je bolest koju uzrokuju gljive mješinarke iz roda Ophiostoma. Tijekom 20. stoljeća zabilježene su dvije pandemije ove bolesti, a točno porijeklo uzročnika još uvijek nije sa sigurnošću potvrđeno. Prva pandemija uzrokovana vrstom Ophiostoma ulmi započela je početkom 20. stoljeća, dok se sredinom 20.

Utjecaj temperaturnog stresa na fitopatogenu gljivu Ophiostoma novo-ulmi
2022Ophiostoma novo-ulmi je fitopatogena gljiva koja uzrokuje holandsku bolesti brijesta. Ova je bolest uzrokovala sušenje velikog broja stabala brijesta i smatra se jednom od najdestruktivnijih bolesti drvenastih biljnih vrsta. Vrsta O. novo-ulmi dijeli se na dvije podvrste: O. novo-ulmi ssp. novo-ulmi i ssp. americana.
