Chromosome-Level Reference Genome of , Causative Agent of Pecan Scab.

Pecan scab, caused by , is a devastating disease of pecan (), which results in economic losses on susceptible cultivars throughout the southeastern United States. To enhance our understanding of pathogenicity in , we have generated a complete telomere-to-telomere reference genome of isolate FRT5LL7-Albino. By combining Illumina MiSeq and Oxford Nanopore MinION data, we assembled a 45.2-Mb genome represented by 20 chromosomes and containing 10,820 putative genes, of which 7,619 have at least one functional annotation. The likely causative mutation of the albino phenotype was identified as a single base insertion and a resulting frameshift in the gene encoding the polyketide synthase . This genome represents the first full chromosome-level assembly of any sp.
