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

Parental material and climate jointly determine the biomass and diversity of soil microbial communities along an elevational gradient on a subtropical karst mountain

Journal of Biogeography, Journal Year: 2024, Volume and Issue: 51(7), P. 1185 - 1198

Published: Feb. 19, 2024

Abstract Aim Climate is widely understood to determine elevational patterns of soil microbial communities, whereas the effects parental material are uncertain. Changes in composition materials along transects could also affect communities by influencing pH and nutrient availability. Here, we aim illustrate combined climate on biomass an transect. Location A subtropical forest a karst mountain (Mt. Jinfo), China. Taxon Bacteria Fungi. Methods We use phospholipid fatty acid analysis (PLFA) DNA amplicon high‐throughput sequencing diversity gradient with contrasting (limestone clasolite). Results observed that were more diverse (α‐diversity) productive (biomass) limestone than clasolite. Additionally, found played role shaping (β‐diversity) gradient. The impact was be significant, albeit relatively weak. Structural equation models provided evidence for both direct indirect α‐diversity Notably, changes pH, influenced climate, identified as key factor driving these effects. Main Conclusions Our results underline importance variations space‐for‐time studies investigating gradients.

Pulses are considered a remarkable and stable source of nutrients, which being presently extensively cultivated consumed in different parts the world. belong to family Leguminosae rich nutrients such as phosphorus (P) nitrogen (N) for best growth via symbiotic relationship with bacteria AMF (arbuscular mycorrhizal fungi). The aim current study was evaluating influence diversity associated various pulses (French bean, mung kidney peas, soybean, peanuts, grams). Furthermore, characterization done using morphological features spores sequencing rDNA gene, confirmed existence 10 taxa. Among genera, genus Glomus observed be most dominant 30% species followed by Gigaspora (22%), Sclerocystis (12%), Acaulospora (8%), Rhizophagus Septoglomus (7%), Diversispora (5%), Claroideoglomus, Archaeospora, Ambispora (3%). soil physicochemical analysis percentage colonization results revealed fact that content (inversely proportional diversity) determining factor diversity. highest amount available (62.825 mg kg-1) district Swabi resulted low rate (6.66 ± 11.54%) comparatively higher (50.66 1.15%) found Chitral having (17.3 7.6 kg-1).
