Recent toolset of metagenomics for taxonomical and functional annotation of marine associated viruses: A review
Abstract
The most prevalent biological species on earth are viruses, the majority of which infect bacteria. Less than 1 % of microbial hosts have been cultured, making it difficult to identify and measure the dynamics of viral communities in the environment. In addition, the viral community in marine biofilms and their functional significance have not been extensively studied. These restrictions could be prevailed over by metagenomic investigations of uncultured viral communities, which can reveal information about marine viral communities. Recent years have witnessed tremendous advancements in the science of virus genomics, which uses sequencing data to study the capabilities of viruses. This review emphasizes important aspects of virus identification and functional annotation using metagenomics and focuses on the industry advancing in the right direction, from how the virus genome predictions are done to the data discovered.
