Description

We report the first chromosome-level assembly for green ash (Fraxinus pennsylvanica) to assist in ash breeding efforts to propagate resistance to the emerald ash borer. The final haploid assembly consists of 23 chromosomes and 87 unplaced scaffolds of 10 kb or more. Over 99% of the bases anchored to the chromosomes. The assembly spans 757 Mb and consists of 49.43% repetitive DNA. Gene annotation yielded 35,470 high-confidence gene models, all located on the chromosomes and assigned to 22,976 Asterid Orthogroups.
