Giant Virus Discovery Could help Predict Algal Blooms
Miami,Fl. – Scientists have identified 230 novel giant viruses in ocean waters, a discovery that could revolutionize our understanding of marine ecosystems and help predict harmful algal blooms.These giant viruses, which infect single-celled marine organisms like algae and amoeba, play a crucial role in the ocean’s food web.
Unlocking The Secrets Of Giant viruses
Researchers at the Rosenstiel School Of Marine, Atmospheric, And Earth Science utilized high-performance computing to analyze marine metagenomic datasets. This led to the identification of these previously unknown giant virus genomes. The findings, published in Nature Npj Viruses, also reveal the discovery of 530 new functional proteins, including nine involved in photosynthesis. This suggests that these viruses can manipulate their hosts during infection.
“By better understanding the diversity and role of giant viruses in the ocean and how they interact with algae and other ocean microbes, we can predict and possibly manage harmful algal blooms,” said Mohammad Moniruzzaman, a co-author of the study and an assistant professor in the Department Of Marine Biology And Ecology. He also noted the biotechnological potential of these novel functions, which might represent novel enzymes.
The Innovative Tool: Beren
Until recently, limitations in bioinformatic pipelines hindered the detection of giant viruses. to overcome this, the researchers developed an innovative tool called Beren (Bioinformatic Tool For Eukaryotic Virus Recovery From Environmental MetageNomes). This tool is designed to identify giant virus genomes within extensive DNA sequencing datasets.
Benjamin Minch, the lead author of the study, explained, “We discovered that giant viruses possess genes involved in cellular functions such as carbon metabolism and photosynthesis-traditionally found onyl in cellular organisms. This suggests that giant viruses play an outsized role in manipulating their host’s metabolism during infection and influencing marine biogeochemistry.”
Impact And Future Applications
The study leveraged the University Of Miami’s Pegasus supercomputer to process large metagenomes, enabling the reconstruction of numerous microbial community libraries.This framework improves existing tools for detecting novel viruses,which could aid in monitoring pollution and pathogens in waterways.
The research team analyzed DNA sequencing data from nine global ocean sampling projects, recovering giant virus genomes using Beren.These genomes were then annotated using publicly available gene function databases to characterize their functions and identify novel functions compared to existing giant virus representatives.
Beren is publicly available for download, offering an accessible tool for identifying and classifying giant viruses in sequencing datasets.

the Broader Implications Of Virus Research
The study of viruses, especially giant viruses, extends beyond just marine biology. Viruses are key players in various ecosystems, influencing nutrient cycles, and shaping microbial communities. Recent advancements in metagenomics and bioinformatics provide unprecedented insights into viral diversity and function. For example, research published in “Cell” in early 2025 highlighted the role of gut bacteriophages in modulating the human immune system, showcasing the broad relevance of virus research to human health.
Did You Know? According to a report by The National Institutes Of Health (NIH) published in March 2025, funding for viral research has increased by 15% in the last year, reflecting the growing recognition of viruses’ importance in both ecological and medical contexts.
Pro Tip: Researchers suggest using multiple databases when analyzing viral genomes to ensure a comprehensive understanding of their functions, as highlighted in a paper in “Bioinformatics” (February 2025).
Understanding these complex interactions is crucial for addressing various environmental and health challenges, from predicting disease outbreaks to mitigating the impact of climate change on marine ecosystems.
