Recovery of American chestnut characteristics following hybridization and backcross breeding to restore blight-ravaged Castanea dentata
Morphological features of leaves and twigs of American chestnut, Chinese chestnut, their F1 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 resistance. In aggregate morphology, as measured by a c...
متن کاملSynthesis of American chestnut (Castanea dentata) biological, ecological, and genetic attributes with application to forest restoration
Introduction American chestnut (Castanea dentata (Marsh.) Borkh. once occurred over much of the eastern deciduous forests of North America (Russell, 1987), with a natural range exceeding 800,000 km (Braun, 1950) (Figure 1). Castanea dentata was a dominant tree species throughout much of its range, comprising between 25-50% of the canopy (Braun, 1950; Foster et al., 2002; Russell, 1987; Stephens...
متن کاملDistribution and Persistence of American Chestnut Sprouts, Castanea dentata (Marsh.) Borkh., in Northeastern Ohio Woodlands
Sprouts and stumps of American chestnut, Castanea dentata [Marsh.] Borkh., were mapped from data collected at three forested sites of varying size and historical background in Cuyahoga County of northeast Ohio to compare the species' present distribution with that of its historical distribution in the mentioned areas. Sprouts were absent from one site despite a dense population of remnant chest...
متن کاملSpecies-specific duplications of NBS-encoding genes in Chinese chestnut (Castanea mollissima)
The disease resistance (R) genes play an important role in protecting plants from infection by diverse pathogens in the environment. The nucleotide-binding site (NBS)-leucine-rich repeat (LRR) class of genes is one of the largest R gene families. Chinese chestnut (Castanea mollissima) is resistant to Chestnut Blight Disease, but relatively little is known about the resistance mechanism. We iden...
