Nature综述：Microbiota, metagenome, microbiome傻傻分不清
Metagenomics is the study of genetic material recovered directly from environmental samples. The broad field may also be referred to as environmental genomics, ecogenomics or community genomics.
Metagenomics - Wikipedia
Metagenomics is the study of genetic material recovered directly from environmental or clinical samples by a method called sequencing. The broad field may also be referred to as environmental genomics, ecogenomics, community genomics or microbiomics.
宏基因组 - 百度百科
宏基因组学 (或元基因组学，metagenomics)是一种以环境样品中的微生物群体基因组为研究对象，以功能基因筛选和/或测序分析为研究手段，以微生物多样性、种群结构、进化关系、功能活性、相互协作关系及与环境之间的关系为研究目的的新的微生物研究方法。一般包括从环境样品中提取基因组DNA, 进行高通量测序分析，或克隆DNA到合适的载体，导入宿主菌体，筛选目的转化子等工作。 特定生物种基因组研究使人们的认识单元实现了从单一基因到基因集合的转变，宏基 …
Metagenome - an overview | ScienceDirect Topics
The term metagenome refers to the genetic content of any group of microorganisms. Knowledge of metagenomes has been significantly increased by using the molecular techniques of massive sequencing, especially the second-generation version, also known as next-generation sequencing (NGS), and advances in clone libraries construction and ...
