Abstract

Eriophyoidea represents a highly diverse superfamily of herbivorous mites in the Acariformes, including over 5,000 named species that are distributed worldwide. However, the lack of chromosome-level genome prevents our understanding of the evolution in this group. Here, we report the first chromosome-level genome assembly of Setoptus koraiensis using Illumina, PacBio, and Hi-C sequencing technologies. The assembled genome has a size of 47 Mb with an N50 of 24.53 Mb, anchored into two chromosomes. The chromosome-level genome assembly had a BUSCO completeness of 89%. We identified 5,954 protein-coding genes, with 4,770 genes that could be functionally annotated. This genome provides resources to further understand the genetic and evolution of eriophyoid mites.

摘要

瘿螨总科是真螨目下一个高度多样化的植食性螨类总科，包括5000多种已命名的物种，分布于世界各地。然而，缺乏染色体水平的基因组阻碍了我们对该类群进化的理解。在此，我们报告了利用Illumina、PacBio和Hi-C测序技术首次对朝鲜瘿螨进行的染色体水平基因组组装。组装后的基因组大小为47 Mb，N50为24.53 Mb，锚定到两条染色体上。染色体水平的基因组组装的BUSCO完整性为89%。我们鉴定出5954个蛋白质编码基因，其中4770个基因可以进行功能注释。该基因组为进一步了解瘿螨的遗传学和进化提供了资源。
