摘要:
磷（P）是生态系统中重要的限制性营养元素，其循环过程主要受微生物驱动。长期以来，病毒在磷循环中的生态作用一直被低估。病毒不仅能够通过裂解宿主细胞释放有机磷和无机磷加速磷的再循环，还可通过携带辅助代谢基因（AMGs）重编程宿主磷获取与代谢过程，主动调控磷循环。同时，病毒通过自上而下的调控作用影响微生物群落结构与功能，进一步改变不同功能类群在磷循环中的生态贡献。本文从“裂解释放—宿主代谢调控—群落重塑—生态耦合”四个维度梳理病毒介导磷循环的作用机制，重点解析病毒在磷限制环境中的适应策略，及其与碳、氮循环之间的耦合关系。已有研究主要集中于水生生态系统，而土壤等陆地生态系统中病毒介导磷循环的研究相对薄弱，尤其缺乏病毒相关功能基因表达及其生态效应的直接证据。未来需结合多组学、稳定同位素示踪及生态模型等技术手段，多尺度解析病毒在生态系统养分循环中的功能与生态意义。
Abstract:
Phosphorus (P) is a key limiting nutrient in ecosystems, and its cycling is primarily driven by microorganisms. The ecological functions of viruses in phosphorus cycling has long been underestimated. Recent studies have revealed that viruses facilitate phosphorus recycling by lysing host cells to release organic and inorganic phosphorus. Meanwhile, viruses actively regulate phosphorus cycling via the auxiliary metabolic genes (AMGs) they carry, which reprogram the pathways of host phosphorus acquisition and metabolism. Moreover, viruses impose top-down ecological control over microbial communities, reshaping their structural and functional compositions and further modulating the contributions of distinct functional groups to phosphorus cycling. In this review, we elaborated the mechanisms underlying virus-mediated phosphorus cycling from four perspectives: phosphorus release via lysis, host metabolic regulation, microbial community restructuring, and multi-element ecological coupling. Emphasis was placed on viral adaptive strategies under phosphorus-limited conditions as well as the coupling relationships between phosphorus cycling and carbon/nitrogen cycling. Relevant researches are largely confined to aquatic ecosystems, while investigations on virus-mediated phosphorus cycling in terrestrial ecosystems (especially soils) remain insufficient. In particular, direct evidence linking the expression of viral functional genes to corresponding ecological effects is still absent. Future research should combine multi-omics techniques, stable isotope tracing and ecological models to resolve the ecological functions and biogeochemical implications of viruses in ecosystem nutrient cycling across multiple scales.
