环境基因组学

海洋环境基因组学在海洋生态研究中的应用

Application of marine environmental genomics in marine ecology

如海洋环境基因组学通过测定基因表达谱的变化，研究海洋生物对环境温度的生理响应，绘制出生物地理图谱；

With regard to the ecological role of environmental temperature , marine environmental genomics studies have the potential to reveal changes in gene expression that map onto biogeographical distribution .

而分子生物学在环境基因组学中的应用首先要求得到有广泛代表性的高质量的DNA样品。

In this respect , high quality DNA sample need to be recovered from environmental samples without culturing microorganisms first .

在水生物疾病的研究方面，海洋环境基因组学用DNA微阵列技术分析染病生物的基因表达谱，筛选出发生变化的基因表达，为理解病毒感染机制提供了大量信息。

The application of DNA microarray technology can analyze gene expression profiling to pick out gene expressions that are generally altered or compromised that might then link to reduced resistance of organisms to disease , providing information for viral infection mechanisms .

目前，快速发展中的环境DNA测序学科（简称环境基因组学），为这一难题的解决提供了帮助。

The rapidly growing field of environmental DNA sequencing , called metagenomics , now helps to overcome this problem .

随着分子生物学的快速发展及其在微生物研究中的广泛运用，促进了以环境中未培养微生物为研究对象的新兴学科&环境基因组学的产生和发展。

With the development of molecular biology and its application in microbiology , a new research field , namely environmental genomics , has been developed .
