Agrobacterium-mediated transformation of American chestnut (Castanea dentata (Marsh.) Borkh.) somatic embryos

Plant Cell, Tissue and Organ Culture, 2005
These studies were designed to test if a binary vector containing the gfp, bar and oxalate oxidase genes could transform American chestnut somatic embryos; to see if a desiccation treatment during co-cultivation would affect the transformation frequency of different American chestnut somatic embryo clones; to explore the effects of more rapid ...

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 ...

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 ...

Aboveground carbon biomass of plantation-grown American chestnut (Castanea dentata) in absence of blight

Forest Ecology and Management, 2009
Forest management activities may help reduce global net CO2 concentrations by capturing and storing atmospheric CO2. Research related to carbon sequestration potential of plantations in North America has focused predominantly on conifers, with relatively little emphasis thus far on temperate deciduous forest tree species.

The effects of oxalic acid on transgenic Castanea dentata callus tissue expressing oxalate oxidase

Plant Science, 2007
The American chestnut, Castanea dentata (Marsh.) Borkh, has been decimated by chestnut blight which is caused by an exotic, oxalate producing pathogen, Cryphonectria parasitica (Murrill.) Barr. Many pathogenic and saprophytic fungi produce oxalate to facilitate in colonization of plant tissue, and therefore, discovering ways to protect plants from the ...

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.

Molecular characterization of a gene encoding a cystatin expressed in the stems of American chestnut ( Castanea dentata )

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.

Recovery of American chestnut characteristics following hybridization and backcross breeding to restore blight-ravaged Castanea dentata

Forest Ecology and Management, 2006
Abstract Morphological features of leaves and twigs of American chestnut, Chinese chestnut, their F 1 hybrid, and three successive generations of backcrosses between hybrid populations and American chestnut were examined to determine rate of recovery of the American chestnut morphology after hybridization to capture Chinese chestnut genes for blight

Evidence that Castanea Dentata Persists on Xeric, Mid-Elevation Sites in the Southern Appalachians

Journal of the North Carolina Academy of Science, 2017
Abstract:  Castanea dentata (American chestnut) persists today in the southern Appalachian forests of North Carolina as sparsely occurring sprouting root systems. The introduction of two exotic fungal diseases into North America, root rot (Phytophthora cinnamomi) in the early 1800s and chestnut blight (Cryphonectria parasitica) in ...
