This paper reports a chromosome-level genome assembly for the spider mite Tetranychus cinnabarinus, combining Illumina, Oxford Nanopore, and Hi-C sequencing to generate an 86.67 Mb assembly with an N50 of 21.77 Mb and 84.54 Mb anchored across three chromosomes. The authors assessed assembly quality using BUSCO completeness (92.78%) and used gene prediction to identify 11,388 protein-coding genes, with 98.53% functionally annotated. They also cataloged 304 detoxification-related genes across five major detoxification enzyme systems, explicitly framed in the context of pesticide resistance mechanisms, while noting that the work’s main limitation is its focus on resource generation rather than functional validation. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

Tetranychus cinnabarinus is an important agricultural pest, primarily due to its rapid development of pesticide resistance. In this study, we constructed a chromosome-level genome of T. cinnabarinus using Illumina, Nanopore, and Hi-C sequencing technologies. The assembled genome spans 86.67 Mb, with an N50 value of 21.77 Mb, and 84.54 Mb of sequences anchored across three chromosomes. The BUSCO completeness of the genome is 92.78%. Through gene prediction, we identified 11,388 protein-coding genes, 98.53% of which are functionally annotated. Furthermore, we systematically identified 304 genes from five major detoxification enzyme systems. This high-quality genome provides a solid foundation for investigating the physiological mechanisms of T. cinnabarinus and for identifying potential targets for biocontrol strategies.
