What is Marine Bacteriophage Metagenomics?

Marine Bacteriophage Metagenomics sequences uncultivated viral communities from ocean samples to reconstruct phage genomes, identify auxiliary metabolic genes, and predict host interactions in marine microbiomes.

Researchers apply high-throughput sequencing to viromes across ocean layers, using tools like VirSorter2 (Guo et al., 2021, 1182 citations) for virus detection and MIUViG standards (Roux et al., 2018, 727 citations) for genome reporting. Over 100 papers since 2015 document diverse tailed phages and giant viruses, with key works like Roux et al. (2016, 873 citations) revealing biogeochemical impacts. Bioinformatic pipelines enable host prediction without isolation (Edwards et al., 2015, 490 citations).

Key Challenges

Why It Matters

Marine phages regulate microbial populations, driving carbon and nutrient cycles essential for global primary production (Roux et al., 2016). They carry auxiliary metabolic genes that enhance host metabolism during infection, influencing ocean carbon sequestration (Coutinho et al., 2017). Phage-induced virocells alter microbial community dynamics, with metabolic reprogramming observed in ocean viruses (Howard-Varona et al., 2020). These processes affect climate models and marine ecosystem management.

Key Research Challenges

Virus detection in metagenomes

Low viral abundance and host contamination complicate identification from marine samples. VirSorter2 addresses this with multi-classifier approaches but misses RNA viruses (Guo et al., 2021). Platform choices like Illumina versus long-read sequencing impact recovery (Solonenko et al., 2013).

Host prediction accuracy

Computational tools struggle with sequence divergence between phages and hosts. Methods like those in Edwards et al. (2015) rely on CRISPR spacers but lack precision for novel marine phages. Integration of genomic and ecological data remains unresolved.

Genome assembly fragmentation

Short reads yield fragmented assemblies for giant phages and RNA viromes. Clades of huge phages require advanced binning (Al-Shayeb et al., 2020). MIUViG standards help reporting but not assembly quality (Roux et al., 2018).
