Chestnut blight and recovering American chestnut trees in Michigan
Canadian Journal of Botany, 1983Stands of American chestnut trees have survived in Michigan in spite of the presence of Endothia parasitica. Cankered trees were evaluated in eight groves in seven of which two types of abnormal cankers were observed. These abnormal cankers resulted when diseased periderm was replaced by wound periderm.

American Chestnut— Castanea dentata
2023This chapter recounts how the American chestnut once occupied a significant portion of many forests, yielding food, timber, and structure for people and wildlife. The loss of the American chestnut set the stage for much of the forest structure America has today.

The American Chestnut's Genetic Rebirth
Scientific American, 2014The article discusses genetic engineering efforts in the conservation of the American chestnut tree, focusing on work by the authors and others to develop fungus-resistant "transgenic" trees. Topics include the cryphonectria parasitica fungus epidemic, techniques aimed at reviving the American chestnut including hybridization with the Chinese chestnut ...

Somatic embryogenesis in American chestnut
Canadian Journal of Forest Research, 1991Cultures were initiated from developing ovules and excised embryos of American chestnut (Castaneadentata (Marsh.) Borkh.), collected from five source trees on three dates during early and middle stages of fruit development. Explants were cultured initially on semisolid induction medium containing 0.25 mg/L benzyladenine and either 6 mg/L ...

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 ...

Chestnut, American (Castanea dentata (Marsh.) Borkh.)
2014The 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 ...

Enhancement of American chestnut somatic seedling production
Plant Cell Reports, 2005Somatic embryogenesis holds promise for mass propagation of American chestnut trees bred or genetically engineered for resistance to chestnut blight. However, low germination frequency of chestnut somatic embryos has limited somatic seedling production for this forest tree.
