First interspecific genetic linkage map for Castanea sativa x Castanea crenata revealed QTLs for resistance to Phytophthora cinnamomi
The Japanese chestnut (Castanea crenata) carries resistance to Phytophthora cinnamomi, the destructive and widespread oomycete causing ink disease. The European chestnut (Castanea sativa), carrying little to no disease resistance, is currently threatened by the presence of the oomycete pathogen in forests, orchards and nurseries. Determining the genetic basis of P. cinnamomi resistance, for fur...
متن کاملAssessing ectomycorrhizal associations and transgene expression in transgenic Castanea dentata
Background American chestnut (Castanea dentata) once dominated the forests of the eastern United States until the introduction of a Chinese fungal pathogen Cryphonectria parasitica(causal agent of the chestnut blight) decimated the species. This tree was important not only ecologically, but also played a significant role economically. Restoration programs are implementing a variety of technique...
متن کاملMapping and transcriptomic approches implemented for understanding disease resistance to Phytophthora cinammomi in Castanea sp
The European chestnut, Castanea sativa Mill, covers a total area of 2.53 million hectares two million of which are chestnut forests, i.e. forests where chestnut is the dominant tree species, being the remaining 0.53 million hectares devoted to fruit production (20.9% of the total chestnut-growing area). Chestnut fruit production in Europe declined considerably during the XX century to the curre...
متن کاملEffect of soil compaction and moisture on incidence of phytophthora root rot on American chestnut (Castanea dentata) seedlings
American chestnut is one of hundreds of plant species plagued by root rot caused by Phytophthora cinnamomi. Phytophthora root rot is thought to have contributed to chestnut dieback prior to the arrival of chestnut blight, and it may now present a serious limitation to establishment of blight-resistant hybrid chestnut. We manipulated soil compaction and moisture to evaluate the effect of soil ph...
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...
