Fraxinus excelsior (European Ash) is widespread throughout Europe and is of great ecological and economic value. It is currently threatened by the fungal pathogen Hymenoscyphus fraxineus, the causative agent of ash dieback disease, which has now been found in every European country within the tree’s range. Natural genetic variation within ash populations yields a small percentage of low-susceptibility individuals, which could provide a basis for the selective breeding of disease resistance. The British Ash Tree Genome Project has provided a reference F. excelsior genome sequence (N50 of 98 kbp) of a low heterozygosity British ash tree produced by self-pollination.
