Distribution, metabolic capacities and phage-host interactions of the Roseobacter group in marine sediments (A02)

本项目将从各种宏基因组数据集中研究迄今为止未知的底栖玫瑰杆菌，并将其定义为具有特定功能概况的新底栖菌群。此外，2017年将对从太平洋游轮上分离出来的生物进行基因组测序，以确定底栖生物栖息地的特定特征。另一个方面论述了底栖玫瑰杆菌中噬菌体的作用。将进行噬菌体诱导实验，以确定噬菌体-宿主相互作用的特征参数。我们还将在太平洋沉积物的宏基因组中寻找玫瑰噬菌体特异性特征，并使用噬菌体特异性引物通过qPCR量化其在原始沉积物样品中的分布。

This project will study so far unknown benthic roseobacters from various metagenomic data sets and define them as new benthic clusters with specific functional profiles. Further, isolates from cruises to the Pacific in 2017 will be genome sequenced to identify specific features for life in benthic habitats. Another aspect addresses the role of phages for benthic roseobacters. Phage-induction experiments will be performed to determine characteristic parameters for phage-host interactions. We will also search for roseophage-specific signatures in the metagenomes from Pacific sediments and quantify their distribution in original sediment samples by qPCR using phage-specific primers.
