Metatranscriptomic insights into organic amendment-induced shifts in soil microbial life history strategies

This study investigates the effects of long-term fertilization treatments on soil microbial community functions and life history strategies, based on metatranscriptomic data from soil samples under different fertilization regimes. Through metatranscriptomic sequencing, we revealed the differential regulation of microbial gene expression by various fertilization practices, including organic, chemical, and combined fertilization. The focus was on examining the relationship between soil resource availability, pH changes, and microbial life history strategies (e.g., Y, A, and S strategies).

本研究基于不同施肥制度下土壤样本的宏转录组（metatranscriptomic）数据，探究长期施肥处理对土壤微生物群落功能与生活史策略的影响。通过宏转录组测序，本研究揭示了有机肥、化肥及配施等不同施肥模式对微生物基因表达的调控差异。本研究重点探讨了土壤资源可获得性、pH变化与微生物生活史策略（如Y、A、S策略）之间的关联。
