375-Bin Chicken:针对罕见微生物组的高效宏基因组共组装工具

from 聊聊Sci

这篇研究介绍了一种名为 Bin Chicken 的新型算法工具,旨在通过自动化的定向协同组装技术,从庞大的宏基因组数据集中高效挖掘稀有微生物基因组。该工具利用原始读取中的标记基因序列来识别并聚集相关的宏基因组样本,有效解决了低丰度物种因测序深度不足而难以被完整回收的难题。研究人员将其应用于约 20 万个公开宏基因组样本,成功构建了包含超过 7.7 万个中高质量基因组的“稀有生物圈基因组”库。这一成果发现了 2.4 万个新物种以及 6 个全新的门级谱系,显著填补了生命之树的空白。此外,分析表明这些新发现的微生物多具有独特的厌氧代谢潜力和丰富的未知蛋白质功能。总而言之,该研究为探索地球上尚未被描述的微生物多样性提供了一种高效率且低成本的计算方案。References: Aroney S T N, Newell R J P, Tyson G W, et al.
