Optimizing genomic selection for blight resistance in American chestnut backcross populations: A trade‐off with American chestnut ancestry implies resistance is polygenic

open access: yesEvolutionary Applications, 2020
American chestnut was once a foundation species of eastern North American forests, but was rendered functionally extinct in the early 20th century by an exotic fungal blight (Cryphonectria parasitica).

Beyond blight: Phytophthora root rot under climate change limits populations of reintroduced American chestnut

open access: yesEcosphere, 2022
American chestnut (Castanea dentata) was functionally extirpated from eastern US forests by chestnut blight, caused by a fungus from Asia. As efforts to produce blight‐resistant American chestnut germplasm advance, approaches to reintroduce chestnut ...

A silvicultural synthesis of sweet (Castanea sativa) and American (C. dentata) chestnuts

open access: yesForest Ecology and Management, 2023
Sweet chestnut (Castanea sativa) and American chestnut (C. dentata) have been explicitly linked to ancient, historical, and contemporary cultures while enhancing ecological services in forests in which they occur. Threats that currently face these chestnut species are unprecedented and additive, including global climate change, nonnative pest and ...

Comparison of Biochemical Constituents and Contents in Floral Nectar of Castanea spp.

open access: yesMolecules, 2020
Pollination is essential for efficient reproduction in pollinator-dependent crops that rely on the attraction of pollinators to flowers. Especially, floral nectar is considered to be an important factor attracting pollinator like honey bees, but ...

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

open access: yesLetters 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.

Reconsidering the fire ecology of the iconic American chestnut

open access: yesEcosphere, 2020
The iconic American chestnut (Castanea dentata) once spanned a large portion of eastern North America before its functional extinction in the early 20th century due primarily to non‐native fungal pathogens.

Fine‐Scale Spatial Genetic Structure and Leaf Shape Variation in Five Fagaceae Species: Insights Into Conservation and Adaptation

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
We investigated both fine‐scale SGS and leaf shape variation in five Fagaceae species (Q. glauca, Q. multinervis, C. tibetana, C. faberi, and C. fargesii) from the genera Quercus and Castanopsis in Wuyishan National Park. We found that Quercus species exhibit stronger fine‐scale SGS than Castanopsis species.

Soil Metals and Ectomycorrhizal Fungi Associated with American Chestnut Hybrids as Reclamation Trees on Formerly Coal Mined Land

open access: yesInternational Journal of Agronomy, 2017
Hybrid chestnut (Castanea dentata × C. mollissima) has the potential to provide a valuable agroforestry crop on formerly coal mined landscapes. However, the soil interactions of mycorrhizal fungi and buried metals associated with mining are not known ...
