Chromosome-scale reference genomes for two walnuts: Juglans ailantifolia and Juglans cinerea implicate gene presence and absence in fungal defense divergence

Butternut (Juglans cinerea) is a North American hardwood in rapid decline, driven largely by butternut canker disease (BCD). Within the genus, Juglans ailantifolia (Japanese walnut) is comparatively resistant and hybridizes readily with J. cinerea, yet the genomic basis of the difference is unresolved. The first chromo...
