High-resolution silkworm pan-genome provides genetic insights into artificial selection and ecological adaptation.

The silkworm Bombyx mori is an important economic insect for producing silk, the "queen of fabrics". The currently available genomes limit the understanding of its genetic diversity and the discovery of valuable alleles for breeding. Here, we deeply re-sequence 1,078 silkworms and assemble long-read genomes for 545 representatives.

Identification and complete genome sequence of mulberry cryptic virus 1.

A cryptic virus, named mulberry cryptic virus 1 (MuCV1), was identified in a mulberry (Morus alba) transcriptome dataset and confirmed using RACE methods. The genome of MuCV1 is composed of two double-stranded RNAs, 1605 bp and 1627 bp in size, encoding an RNA-dependent RNA polymerase (RdRp) and a coat protein (CP), respectively. The 5'-AGAAUU-3' sequence in the 5' untranslated region was conserved in the two dsRNAs.

Complete mitochondrial genome and phylogenetic analysis of strain Shiquan.

is generally thought to be the wild ancestor nearest to the domesticated silkworm, . Here, we report the complete mitochondrial genome (mitogenome) of strain Shiquan. The mitogenome contains 13 protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes, and one A + T-rich region.
