Vertical transport and spatiotemporal dynamics of giant viruses in the North Pacific subtropical gyre.

ABSTRACT: Nucleocytoplasmic large DNA viruses, or "giant viruses," are prevalent in marine environments, infecting diverse eukaryotic lineages and influencing the marine carbon cycle. Their genomes harbor wide range of auxiliary metabolic genes that influence biogeochemical processes. This study integrates planktonic (5-4000 m) and particle-associated (4000 m) metagenomic samples in the North Pacific Subtropical Gyre, along with particulate export flux data at 4000 m, to investigate the vertical transport of giant viruses and their correlation with carbon export through space and time. By analyzing metagenomic samples over a period of 6 years across 15 depths, we curated a database of 37 giant virus population genomes and 1496 contigs and investigated their spatiotemporal variability and functional
