Abstract

Several species of the genus have been recognized as major agricultural pests from different regions of the world, among which species has been reported as the most destructive and cosmopolitan species in most regions of the world, including Iran. This pest is a polyphagous species and can cause damage to more than 120 plant species. Studying the internal microbiome of pests is very important in identifying species' weaknesses and natural enemies and potential biological control agents. For genomic characterization of the microbial community associated with , the whole genome of insect larvae collected from vegetable fields in the northwest of Iran was sequenced using next-generation sequencing Illumina platform. Finally, about 2 GB of raw data were obtained. Using the MetaPhlAn2 pipeline, it was predicted that 2 endosymbiont bacterial species including and were associated with Alignment of reference strains sequences related to both endosymbiotic bacteria with raw data and subsequently, assembly analyses resulted in 2 genomes with 657 623 bp length with GC content of 27.4% for and 1 595 135 bp length with GC content of 42.90% for This research is the first report on the association of and as endosymbiotic bacteria with worldwide.

摘要

该属的几个物种已被公认为来自世界不同地区的主要农业害虫,其中,[物种名称]在世界大部分地区,包括伊朗,被报道为最具破坏性和分布最广的物种。这种害虫是多食性物种,可对120多种植物造成损害。研究害虫的内部微生物组对于识别物种的弱点、天敌和潜在的生物控制剂非常重要。为了对与[物种名称]相关的微生物群落进行基因组表征,使用下一代测序Illumina平台对从伊朗西北部菜地采集的昆虫幼虫的全基因组进行了测序。最后,获得了约2GB的原始数据。使用MetaPhlAn2管道预测,包括[细菌物种1名称]和[细菌物种2名称]在内的2种内共生细菌物种与[物种名称]相关。将与这两种内共生细菌相关的参考菌株序列与原始数据进行比对,随后进行组装分析,得到了2个基因组,[细菌物种1名称]的基因组长度为657623bp,GC含量为27.4%,[细菌物种2名称]的基因组长度为1595135bp,GC含量为42.90%。这项研究是关于[细菌物种1名称]和[细菌物种2名称]作为内共生细菌与[物种名称]在全球范围内关联的首次报道。
