我们描述了一种方法,将长读段测序添加到用于组装高度复杂的牛瘤胃微生物群落的技术组合中,并提供了与基于短读段的方法的比较。长读比对和序列间的Hi-C连锁支持了188种新型病毒-宿主关联的鉴定和瘤胃微生物群落中噬菌体生命周期状态的测定。长读片段还鉴定出94个抗微生物药物抗性基因,而短读片段仅鉴定出7个等位基因。我们展示了在高度复杂的瘤胃微生物群落中协同工作以提高生物学特征表征的新技术。
We describe a method that adds long-read sequencing to a mix of technologies used to assemble a highly complex cattle rumen microbial community, and provide a comparison to short read-based methods. Long-read alignments and Hi-C linkage between contigs support the identification of 188 novel virus-host associations and the determination of phage life cycle states in the rumen microbial community. The long-read assembly also identifies 94 antimicrobial resistance genes, compared to only seven alleles in the short-read assembly. We demonstrate novel techniques that work synergistically to improve characterization of biological features in a highly complex rumen microbial community.
