资源简介:
The Baylor College of Medicine recently sequenced and annotated the Oncopeltus fasciatus genome as part of the i5k pilot project.
The O. fasciatus research community has manually reviewed and curated the computational gene predictions and generated an official gene set, OGSv1.1.
Oncopeltus fasciatus has been an established lab organism for over 60 years, and has been used for a wide range of studies from physiology to development and evolution. As a relatively conservative and generalized species, it affords a baseline against which other species can be compared.
For example, this species has the same piercing and sucking type mouthparts as its less benign relatives, including the blood-sucking kissing bug, Rhodnius prolixus, and the brown marmorated stink bug, Halyomorpha halys, which are disease vector and agricultural pest species, respectively. Unlike the pest species, the benign, seed-feeding Oncopeltus can be functionally investigated in the lab by RNA interference (RNAi). Comparing the genomes, and conducting experimental lab work in Oncopeltus, will help to identify unique features of the pest species, and thus inform management strategies for them.
More generally, Oncopeltus is a key species for comparisons across the insects. It is one of the few experimentally tractable hemimetabolous species that can ground comparisons with the completely metamorphosing species of the Holometabola (e.g., flies, beetles, wasps). Topics investigated in this framework include reproductive biology and development of the legs, wings, body segments, extraembryonic membranes, and overall establishment of the body plan.
This dataset presents the Oncopeltus fasciatus genome v1.0. This assembly version is the pre-release version, prior to filtering and quality control by the National Center for Biotechnology Information's GenBank resource (http://www.ncbi.nlm.nih.gov/assembly/GCA_000696205.1/). Assembly method details will be available in a forthcoming publication.

Baylor College of Medicine 近期已完成 Oncopeltus fasciatus 基因组的测序与注释工作,此项目作为 i5k 试点项目的一部分。O. fasciatus 研究领域已对计算基因预测进行人工审核和整理,并生成官方基因集 OGSv1.1。Oncopeltus fasciatus 作为实验室模型生物已超过 60 年历史,其应用范围广泛,涵盖生理学、发育和进化等多个研究领域。作为一种相对保守且通用的物种,它为比较其他物种提供了一个基准。例如,该物种与吸血的接吻虫 Rhodnius prolixus 和褐缘蝽 Halyomorpha halys 等不良亲缘物种具有相同的刺吸式口器,后者分别作为疾病传播者和农业害虫。与害虫物种不同,良性的种子食用型 Oncopeltus 可以通过 RNA 干扰(RNAi)在实验室中进行功能研究。通过比较基因组,并在 Oncopeltus 中进行实验性实验室工作,有助于识别害虫物种的独特特征,从而为害虫管理策略提供信息。更普遍地,Oncopeltus 是昆虫跨物种比较的关键物种。它是少数可进行实验性研究的半变态物种之一,可以与全变态物种的 Holometabola(例如,苍蝇、甲虫、黄蜂)进行比较。在此框架下研究的内容包括生殖生物学、腿、翼、体节、胚外膜以及整体身体计划的建立。本数据集展示了 Oncopeltus fasciatus 基因组 v1.0。此组装版本为预发布版本,在经过美国国家生物技术信息中心 GenBank 资源(http://www.ncbi.nlm.nih.gov/assembly/GCA_000696205.1/)的过滤和质量控制之前。组装方法细节将在即将发表的论文中提供。如需使用此数据集,请遵循 Baylor College of Medicine 的数据使用条件:https://www.hgsc.bcm.edu/bcm-hgsc-conditions-use。附:美洲狼蛛照片的归属信息:Oncopeltus fasciatus,Creative Commons Attribution Non Commercial Share Alike 2.0(CC BY-NC-SA 2.0)© Patrick Coin。本数据集包含的资源:资源标题:Oncopeltus fasicatus 基因组装 v1.0 的 contigs 和 scaffolds 的 fasta 和 agp 文件。文件名:Ofas_v1.0.tar__0.gz。资源描述:附带的 tar.gz 压缩文件(Ofas_v1.0.tar_.gz)包含以下文件:
