Abstract：
The broad mite, Polyphagotarsonemus latus (Tarsonemidae: Acari) is a highly polyphagous species that damage plant species spread across 57 different families. This pest has developed high levels of resistance to some commonly used acaricides. In the present investigation, we deciphered the genome information of P. latus by PacBio HiFi sequencing. P. latus is the third smallest arthropod genome sequenced so far with a size of 49.1 Mb. The entire genome was assembled into two contigs. A set of 9,286 protein-coding genes were annotated. Its compact genome size could be credited with multiple features such as very low repeat content (5.1%) due to the lack of proliferation of transposable elements, high gene density (189.1/Mb), more intronless genes (20.3%) and low microsatellite density (0.63%).
摘要：
广泛的螨，多食多食动物（Tarsonemidae：Acari）是一种高度多食的物种，会损害分布在57个不同科的植物物种。这种害虫对一些常用的杀螨剂产生了高水平的抗性。在目前的调查中,我们通过PacBioHiFi测序破译了P.latus的基因组信息。P.latus是迄今为止测序的第三小节肢动物基因组，大小为49.1Mb。将整个基因组组装成两个重叠群。注释了一组9,286个蛋白质编码基因。由于缺乏转座因子的增殖，其紧凑的基因组大小可以被认为具有多种特征，例如非常低的重复含量（5.1％）。高基因密度（189.1/Mb），更多的无内含子基因(20.3%)和低微卫星密度(0.63%)。
