Massive sequencing of Ulmus minor's transcriptome provides new molecular tools for a genus under the constant threat of Dutch elm disease

Frontiers in Plant Science, 2015
Elms, especially Ulmus minor and Ulmus americana, are carrying out a hard battle against Dutch elm disease (DED). This vascular wilt disease, caused by Ophiostoma ulmi and O. novo-ulmi, appeared in the twentieth century and killed millions of elms across

Lack of Association between Cerato-ulmin Production and Virulence inOphiostoma novo-ulmi

Molecular Plant-Microbe Interactions, 1996
Cerato-ulmin (CU), a hydrophobin produced by Ophiostoma novo-ulmi, has been implicated in the pathogenicity of this fungus on elm. We have generated a CU- mutant by transformation-mediated gene disruption of a highly virulent (aggressive) strain of O. novo-ulmi.

Biological invasions: a global assessment of geographic distributions, long‐term trends, and data gaps

Biological Reviews, Volume 100, Issue 6, Page 2542-2583, December 2025.
ABSTRACT Biological invasions are one of the major drivers of biodiversity decline and have been shown to have far‐reaching consequences for society and the economy. Preventing the introduction and spread of alien species represents the most effective solution to reducing their impacts on nature and human well‐being.

Seven Ulmus minor clones tolerant to Ophiostoma novo-ulmi registered as forest reproductive material in Spain

iForest - Biogeosciences and Forestry, 2015
The Spanish elm programme began in 1986 in response to the devastating impact of Dutch elm disease on natural elm stands and urban trees. Its main objectives were to conserve remaining genetic resources and select and breed tolerant native elm genotypes.

Leaf Diffuse Reflectance Spectroscopy for Early Detection of Ceratocystis Wilt in Eucalyptus Cuttings

Forest Pathology, Volume 55, Issue 6, December 2025.
ABSTRACT The increasing global demand for products derived from Eucalyptus spp. has stimulated its production in Brazil. However, productivity has declined in recent years due to several factors, with Ceratocystis wilt being one of the most significant.

Potential impacts of plant pests and diseases on trees and forests in the United Kingdom

PLANTS, PEOPLE, PLANET, Volume 7, Issue 5, Page 1538-1550, September 2025.
The UK Plant Health Risk Register (PHRR) has so far identified 581 Plant Pests and Diseases (PPDs) that could invade the United Kingdom and affect 74 tree species. The combined effects of multiple invasions on trees are little understood and seldom considered.

Est-il possible de tirer des enseignements des introductions anciennes d’agents pathogènes ? L’exemple de la graphiose de l’orme

Revue Forestière Française, 2018
La graphiose ou maladie hollandaise de l’orme a été détectée il y a près de cent ans dans le nord-est de la France. Depuis, elle s’est largement répandue au point d’être considérée comme une des maladies les plus destructives jamais observée sur ligneux,

Drought, Waterlogging and Co‐Infection Influence the Severity of Coniella granati and Phytophthora palmivora in Pomegranate and the Biocontrol Efficacy of Bacillus amyloliquefaciens

Plant Pathology, Volume 74, Issue 5, Page 1187-1196, June 2025.
The study evaluates for the first time the efficacy of Bacillus amyloliquefaciens to provide protection against pathogens in pomegranate under co‐infection, drought and waterlogging scenarios. ABSTRACT Cultivation of pomegranate (Punica granatum) is threatened by the emerging pathogens Coniella granati and Phytophthora palmivora.

Special delivery: A hardwood‐killing bark beetle vectors its unusual symbiote among host trees

Ecosphere, Volume 16, Issue 5, May 2025.
Abstract In mutualistic symbioses with fungi, herbivorous insects such as bark beetles (Coleoptera: Curculionidae: Scolytinae) gain access to resources that are unavailable in the absence of fungal mutualists, while fungi benefit from insect‐vectored dispersal. The most well‐studied mutualists of tree‐killing bark beetles in conifer systems are certain

Health status deterioration in field-protective forest belts in northeastern Bulgaria [PDF]

Silva Balcanica
A system of field-protective forest belts was created in the 1950-60s in northeastern Bulgaria to maintain soil moisture, reduce wind speed and protect soil against wind erosion, improve the microclimate, and increase the fertility of agricultural lands.
