ABSTRACT
We present the first long-read de novo assembly and annotation of the luna moth (Actias luna) and provide the full characterization of heavy chain fibroin (h-fibroin), a long and highly repetitive gene (>20 kb) essential in silk fiber production. There are >160,000 described species of moths and butterflies (Lepidoptera), but only within the last 5 years have we begun to recover high-quality annotated whole genomes across the order that capture h-fibroin. Using PacBio HiFi reads, we produce the first high-quality long-read reference genome for this species. The assembled genome has a length of 532 Mb, a contig N50 of 16.8 Mb, an L50 of 14 contigs, and 99.4% completeness (BUSCO). Our annotation using Bombyx mori protein and A. luna RNAseq evidence captured a total of 20,866 genes at 98.9% completeness with 10,267 functionally annotated proteins and a full-length h-fibroin annotation of 2,679 amino acid residues.
