Viruses are considered to regulate bacterial communities and terrestrial nutrient cycling, yet their effects on metabolism the mechanisms of carbon (C) dynamics during dissolved organic matter (DOM) mineralization remain unknown. Here, we added active inactive bacteriophages (phages) soil DOM with original incubated them at 18 or 23 °C for 35 days. Phages initially (1–4 days) reduced CO2 efflux rate by 13-21% 3–30% but significantly (p < 0.05) increased 4–29% 9–41% after 6 days, raising cumulative emissions 14% 21% °C. decreased dominant taxa community diversity (consistent a "cull-the-winner" dynamic), thus altering predicted microbiome functions. Specifically, phages enriched some (such as Pseudomonas, Anaerocolumna, Caulobacter) involved in degrading complex compounds consequently promoted functions related C cycling. Higher temperature facilitated phage-bacteria interactions, diversity, enzyme activities, boosting 16%. Collectively, impact shifting microbial functions, moderate changes modulating magnitude these processes not qualitatively behavior.

Recent decades have seen growing attention on viruses in the environment and their potential impacts as a result of global epidemics. Due to diversity viral species along with complexity environmental host factors, virus extraction detection methods become key for study ecology.

Potential Roles of Soil Viruses in Karst Forest Soil Carbon and Nitrogen Cycles

Forests, Journal Year: 2025, Volume and Issue: 16(5), P. 735 - 735

Published: April 25, 2025

Soil viruses, ubiquitous and abundant biological entities that are integral to microbial communities, exert pivotal impacts on ecosystem functionality, particularly within carbon (C) nitrogen (N) cycles, through intricate interactions with bacteria, archaea, fungi, other taxa. While their contributions soil dynamics increasingly elucidated, the specific roles of viruses in karst forest remain largely underexplored. Karst ecosystems (covering 15% global terrestrial surface) characterized by unique geological formations, thin patchy layers, high pH Ca2+, rapid hydrological dynamics, collectively fostering environmental conditions may shape viral ecology modulate C N cycling. This perspective synthesizes existing knowledge functions distinctive characteristics soil, proposing potential mechanisms which could influence cycling such fragile ecosystems. regulate cycles both directly indirectly via hosts, mainly including shaping community structure, mediating horizontal gene transfer metabolism, increasing availability alleviating nutrient limitations, promoting sequestration, mitigating climate change. work aims bridge biogeochemical providing insights into sustainable stewardship resilience. We delineate critical gaps propose future perspectives, advocating for targeted metagenomic long-term experimental studies diversity, virus–host-environment interactions, temporal dynamics. Specifically, we advocate following research priorities advance our understanding studies: (I) abundance, activity: characterizing activity forests using metagenomics complementary molecular approaches; (II) virus–host interactions: investigating between key taxa involved cycling; (III) impacts: quantifying lysis fluxes soil; (IV) modeling cycles: developing integrative models incorporate virus-mediated processes frameworks at different spatial scales. Such efforts essential validate hypothesized underlying mechanisms, offering a foundation nature-based solutions facilitate support ecological restoration vulnerable regions amid
