Mapping QTLs for blight resistance and morpho-phenological traits in inter-species hybrid families of chestnut (Castanea spp.)

Frontiers in Plant Science
Chestnut blight (caused by Cryphonectria parasitica), together with Phytophthora root rot (caused by Phytophthora cinnamomi), has nearly extirpated American chestnut (Castanea dentata) from its native range.

Does management improve the state of chestnut (Castanea sativa L.) on Belasitsa Mountain, southwest Bulgaria?

iForest - Biogeosciences and Forestry, 2015
Chestnut forests in the Belasitsa Mountain region of southwest Bulgaria were traditionally intensively managed as orchard-like stands for nut production. More recently, management intensity has been sharply reduced as a result of rural abandonment, which

Portuguese Castanea sativa Genetic Resources: Characterization, Productive Challenges and Breeding Efforts

Agriculture, 2023
Chestnuts are multipurpose trees that grow mainly in the Northern Hemisphere due to their aptitude for fruit and wood production. These trees are vastly significant for the economy and wildlife.

Modeling and Analysis of American Chestnut Populations Subject to Various Stages of Infection

Letters in Biomathematics, 2014
American chestnuts, Castanea dentata, were once a dominant tree in eastern deciduous forests of the United States before the chestnut blight fungus, Cryphonectria parasitica, was introduced unintentionally in the early 1900s in New York.

The Physiological and Biochemical Responses of European Chestnut (Castanea sativa L.) to Blight Fungus (Cryphonectria parasitica (Murill) Barr)

Plants, 2021
The most important disease of European chestnut (Castanea sativa Mill.) is chestnut blight caused by the fungus Cryphonectria parasitica (Murrill) Barr which induces yield reduction in Europe and North America. This study aimed to investigate the impacts

Using art history to explore society's changing connections with agriculture

PLANTS, PEOPLE, PLANET, EarlyView.
Food insecurity is a looming challenge that especially affects those least fortunate. Consumer food choices have a substantial impact on the sustainability of current food systems. Here, we use art as a lens through which to consider our contemporary and historical relationship to one of the world's most crucial crops, the potato, in the context of the

Metabolic convergence on TOR signaling in the chestnut blight fungus and its regulation by host plant signals

New Phytologist, EarlyView.
Proposed model of metabolic convergence on the target of rapamycin (TOR) pathway in Cryphonectria parasitica. Twelve core genes involved in diverse metabolic pathways act as upstream regulators or downstream effectors of TOR kinase. Dysregulation of these genes mimics an inhibited TOR state, leading to restricted hyphal growth and enhanced trehalose ...

Can Airborne eDNA Be Used to Assess the Impacts of Invasive Species on Biodiversity?

Environmental DNA, Volume 8, Issue 6, November‐December 2026.
We sequenced airborne eDNA to target plant and arthropod communities in woodlands with an invasive forest pest present and woodlands with no known infestations. We did not find differences in plant communities; however, we found site differences in the arthropod communities between the infested and non‐infested sites.

The implications of American chestnut reintroduction on landscape dynamics and carbon storage

Ecosphere, 2017
In the eastern United States, American chestnut (Castanea dentata) was historically a major component of forest communities, but was functionally extirpated in the early 20th century by an introduced pathogen, chestnut blight (Cryphonectria parasitica ...
