摘要
The yellow peach moth, Conogethes punctiferalis, is a highly polyphagous pest widespread in eastern and southern Asia. It demonstrates a unique ability to adapt to rotten host fruits and displays resistance to pathogenic microorganisms, including fungi. However, the lack of available genomic resources presents a challenge in comprehensively understanding the evolution of its innate immune genes. Here, we report a high-quality chromosome-level reference genome for C. punctiferalis utilizing PacBio HiFi sequencing and Hi-C technology. The genome assembly was 494 Mb in length with a contig N50 of 3.25 Mb. We successfully anchored 1,226 contigs to 31 pseudochromosomes. Our BUSCO analysis further demonstrated a gene coverage completeness of 96.3% in the genome assembly. Approximately 43% repeat sequences and 21,663 protein-coding genes were identified. In addition, we resequenced 110 C. punctiferalis individuals from east China, achieving an average coverage of 18.4 x and identifying 5.8 million high-quality SNPs. This work provides a crucial resource for understanding the evolutionary mechanism of C. punctiferalis' innate immune system and will help in developing new antibacterial drugs.
