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%).
阔体盲蝽,又名长足盲蝽(盲蝽科:盲蝽),是一种高度多食性物种,危害多达 57 科的植物物种。这种害虫对一些常用杀螨剂产生了很高的抗性。在本研究中,我们通过 PacBio HiFi 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的节肢动物基因组,大小为 49.1Mb。整个基因组被组装成两个连续序列。一组 9286 个蛋白质编码基因被注释。其紧凑的基因组大小可以归功于多种特征,例如由于转座元件缺乏增殖而导致的非常低的重复含量(5.1%)、高基因密度(189.1/Mb)、更多无内含子的基因(20.3%)和低微卫星密度(0.63%)。
