Structure and function of the topsoil metaproteome across global biomes: a survey of the topsoil metaproteome across global biomes

Herein, we evaluated the changes in biological functions in soils across global biomes through the identification and quantification of proteins. This knowledge is essential to provide one stepforward in soil microbial ecology in order to decipher the cellular and molecular mechanisms employed by soil microbial communities to adapt to their environment and to explain the potential responses of microbial communities, and their microbially-driven ecosystem services, to global change and land use. Our study aims to provide the most comprehensive assessment on the structure and function of the topsoil metaproteome across global biomes, and hence provide direct identification of the most domimant protein-encoded functions in terrestrial ecosystems.

本研究通过蛋白质的鉴定与定量分析，评估了全球不同生物群区（biome）土壤中生物学功能的变化。该研究成果可为土壤微生物生态学领域提供关键进展，以解析土壤微生物群落适应环境所采用的细胞与分子机制，并阐释微生物群落及其微生物驱动的生态系统服务对全球变化与土地利用的潜在响应。本研究旨在对全球各生物群区的表层土壤宏蛋白质组（metaproteome）的结构与功能开展最为全面的评估，进而直接鉴定陆地生态系统中占主导地位的蛋白质编码功能。
