American Chestnut [Castanea dentata (Marsh.) Borkh.]
2006The key to successful transformation of American chestnut is having the correct combination of explant tissue, selectable and scorable markers, and a reliable regeneration system. Rapidly dividing somatic embryos, growing as proembryogenic masses, are a suitable tissue; the bar gene is a suitable selectable marker in conjunction with 1.0 to 10 mg/L ...

Castanea, 2020
The American chestnut (Castanea dentata) was once widespread in eastern North America and an ecologically important hardwood tree of deciduous forest communities prior to its near-eradication by chestnut blight (Cryphonectria parasitica). Remnant populations occur across much of its historical range, especially in older forests of the Appalachians and ...

CONSERVATION OF CASTANEA DENTATA GERMPLASM OF THE SOUTHEASTERN UNITED STATES
Acta Horticulturae, 2005The ongoing effort to breed and reintroduce a blight resistant, locally adapted variety of American chestnut (Castanea dentata) requires a broad genetic base. To ensure adequate genetic diversity, we have collected genetic resources from across the southeastern portion of the native range of the species. Finding and breeding surviving C.

Mycorrhiza, 2008
Circa 1900, a farmer from the eastern US planted 11 American chestnut (Castanea dentata) seeds on a newly established farm near West Salem in western Wisconsin. These trees were very successful, producing a large stand of over 6,000 trees. Since this area is well outside the natural range of chestnut, these trees remained free from chestnut blight ...

Dominance of interplanted American chestnut (Castanea dentata) in southwestern Wisconsin, USA
Forest Ecology and Management, 2004American chestnut (Castanea dentata (Marsh.) Borkh.) once dominated the eastern deciduous forests of the USA before nearly all trees throughout the range were annihilated by the introduced pathogen Cryphonectria parasitica (Murr.) Barr. It is anticipated that a blight-resistant hybrid form of American chestnut will be available for reintroduction in ...

New Forests, 2014
Backcross breeding programs have been used to transfer disease resistance and other traits from one forest tree species to another in order to meet restoration objectives. Evaluating the field performance of such material is critical for determining the success of breeding programs.

LINKING COMPETITION AND NONSTRUCTURAL CARBON DYNAMICS IN AMERICAN CHESTNUT (CASTANEA DENTATA)
2021Nonstructural carbohydrates (NSC) are involved in essential plant functions and are closely associated with growth and mortality mechanisms. Quantifying NSC reserves can indicate a plant’s resistance and resilience to stress or injury through damaging agents and environmental change. In this work, we studied seasonal NSC dynamics and responses to inter-

Planta, 2002
A cDNA clone with similarity to genes encoding cystatin was recently isolated from a cDNA library created using mRNA extracted from stem tissues of Castanea dentata (Marsh.) Borkh. (CASde:Pic1). All of the requisite motifs for inhibitory activity were found upon examination of the deduced amino acid sequence.

Expressed sequence tags from stem tissue of the American chestnut, Castanea dentata
Biotechnology Letters, 2001Subtracted and size-selected unsubtracted cDNA libraries were created to examine gene expression in the woody tissues of Castanea dentata. A total of 50 clones were sequenced and comparisons were made to the GenBank database. Expression analysis of 20 selected clones revealed that 13 were expressed predominantly in the stem and leaf tissues, while the ...

Inter- and intra-specific competitiveness of plantation-grown American chestnut (Castanea dentata)
Forest Ecology and Management, 2013Abstract The introduction of the fungal pathogen Cryphonectria parasitica (Murr.) Barr. decimated American chestnut ( Castanea dentata (Marsh.) Borkh.) throughout its native range in North America. A blight-resistant backcross hybrid form of American chestnut has been developed, and these backcross trees are likely to be incorporated into ...
