{Reference Type}: Dataset {Title}: Chromosome-level Genome Assembly of Theretra japonica (Lepidoptera: Sphingidae). {Author}: Yan M;Su BS;Huang YX;Xu ZB;Jiang ZH;Wang X; {Journal}: Sci Data {Volume}: 11 {Issue}: 1 {Year}: 2024 Jul 12 {Factor}: 8.501 {DOI}: 10.1038/s41597-024-03500-z {Abstract}: Theretra japonica is an important pollinator and agricultural pest in the family Sphingidae with a wide range of host plants. High-quality genomic resources facilitate investigations into behavioral ecology, morphological and physiological adaptations, and the evolution of genomic architecture. However, chromosome-level genome of T. japonica is still lacking. Here we sequenced and assembled the high-quality genome of T. japonica by combining PacBio long reads, Illumina short reads, and Hi-C data. The genome was contained in 95 scaffolds with an accumulated length of 409.55 Mb (BUSCO calculated a genome completeness of 99.2%). The 29 pseudochromosomes had a combined length of 403.77 Mb, with a mapping rate of 98.59%. The genomic characterisation of T. japonica will contribute to further studies for Sphingidae and Lepidoptera.
