Altered transcriptional response to nutrient availability in hypovirus‐infected chestnut blight fungus. [PDF]

The EMBO Journal, 1994
The gene lac-1, encoding the enzyme laccase, is one of several genes of the chestnut blight fungus, Cryphonectria parasitica, that are suppressed by virulence-attenuating mycoviruses of the hypovirus group. Two antagonistic regulatory pathways have been shown to govern the activity of the lac-1 promoter: a positive pathway that stimulates transcription

Herbaceous Plants in Forest Ecosystems: One Hundred Fundamental and Applied Questions

Journal of Vegetation Science, Volume 37, Issue 4, July/August 2026.
ABSTRACT Aims Herbaceous plants (herbs) found in the understory of forests contribute substantially to the biodiversity of these ecosystems, as well as being important socio‐culturally, economically, and for advancing ecological theory. However, the ecology of herbs is less well understood compared with woody plants, despite evidence that herbs are ...

Mutagenesis of Putative Acylation Sites Alters Function, Localization, and Accumulation of a Giα Subunit of the Chestnut Blight Fungus Cryphonectria parasitica

Molecular Plant-Microbe Interactions, 1998
Targeted disruption of cpg-1, a gene encoding the G protein Giα subunit, CPG-1, in the chestnut blight fungus, Cryphonectria parasitica, results in reduced mycelial growth, reduced orange pigmentation, loss of virulence, loss of asexual sporulation, and ...

Soil Pathobiome in Agroecosystems and Forests

Plant Pathology, Volume 75, Issue 4, July‐August 2026.
This review synthesises current knowledge on the soil pathobiome across agroecosystems, horticulture, and forests, highlighting how climate change and intensive management disrupt microbial communities and promote pathogen accumulation. It emphasises soil health as a key component of the One Health framework, linking ecosystem, plant, animal, and human

Mycoviruses as Biocontrol Agents: Potential Applications for Managing Pests and Diseases of Oilseed Rape (Brassica napus)

Physiologia Plantarum, Volume 178, Issue 4, July/August 2026.
ABSTRACT Oilseed rape (Brassica napus) production faces a wide range of biotic threats. Pests typically pose a greater threat than diseases to oilseed rape, yet both vary considerably across the major cultivating regions. Management strategies often rely heavily on the use of chemical pesticides which may have harmful effects on the environment, thus ...

The impacts of biological invasions

Biological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Strengthening Predictive Models for Wheat Stem Rust Infection Risk in a Changing Climate: Gaps and Opportunities

Plant Pathology, Volume 75, Issue 3, May–June 2026.
Here we review environmental data underpinning epidemiological models for wheat stem rust, highlighting gaps that, once addressed, would significantly enhance the predictive power of these tools. ABSTRACT Puccinia graminis f. sp. tritici (Pgt) is a major global fungal pathogen that causes stem rust of wheat (Triticum spp.) (the primary and principal ...

European Ash (Fraxinus excelsior) as a Functional Keystone Species Shaping Woodland Flora in the UK

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Ash trees have distinct ecological attributes—their canopy allows a high level of light to penetrate and their foliage decomposes rapidly. Here we used woodland survey data to explore if the prevalence of ash trees has an impact on associated plant communities at a fine spatial scale.

Reconstructing post‐crisis recovery in the hinterlands of Constantinople: A high‐resolution first‐millennium CE pollen record from Lake Yeniçağa (NW Türkiye)

Journal of Quaternary Science, Volume 41, Issue 3, Page 520-539, April 2026.
ABSTRACT Facing a novel plague pandemic, military invasions, and political–economic transformations, societies of the eastern Roman (Byzantine) empire had to adapt to a variety of pressures and new ways of exploiting their natural environments during the mid‐1st millennium CE.
