Expressed sequence tags from stem tissue of the American chestnut, Castanea dentata

Biotechnology Letters, 2001
Subtracted 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 ...

Heterozygote advantage in the American chestnut, Castanea dentata (Fagaceae)

American Journal of Botany, 2003
The American chestnut (Castanea dentata; Fagaceae) was a dominant canopy tree in the Appalachian Mountains of North America. Since the introduction of the chestnut blight fungus (Cryphonectria parasitica; Valsaceae) in America, the American chestnut has been reduced to a predominantly clonal, understory species.

Chestnut, American (Castanea dentata (Marsh.) Borkh.)

2014
The key to successful transformation of American chestnut is having the correct combination of explant tissue, selectable markers, a very robust DNA delivery system, and a reliable regeneration system. The most important components of this transformation protocol for American chestnut are the following: starting out with rapidly dividing somatic ...

American Chestnut [Castanea dentata (Marsh.) Borkh.]

2006
The 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 ...

Remnant American Chestnut (Castanea dentata) Near the Historical Western Range Limit in Southwestern Tennessee

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, 2005
The 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.

Ectomycorrhizal characterization of an American chestnut ( Castanea dentata )-dominated community in Western Wisconsin

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, 2004
American 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 ...

Leaf physiology and morphology of Castanea dentata (Marsh.) Borkh., Castanea mollissima Blume, and three backcross breeding generations planted in the southern Appalachians, USA

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)

2021
Nonstructural 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-
