Great Barrier Reef seawater microbiomes genome database

Microbes play a critical role in nutrient-deplete habitats such as coral reefs, where they mediate efficient nutrient recycling. With reefs under increasing pressure from environmental changes, a greater understanding of microbial contributions to reef health is urgently needed. The Integrated Marine Observing System (IMOS) Great Barrier Reef Microbial Genomics Database (GBR MGD) was established to provide high-quality genomic references to increase our understanding of the role of microbes in reef environments. Sample collections from 48 sites on the GBR and a hybrid assembly process was used to combine Illumina and Nanopore sequencing data to generate ~5000 microbial genomes, complemented with comprehensive water chemistry and benthic reef survey data.

微生物在珊瑚礁等养分匮乏生境中发挥关键作用，可介导高效的养分循环过程。当前珊瑚礁正面临日益加剧的环境变化压力，亟需更深入地了解微生物对珊瑚礁健康的贡献。整合海洋观测系统（Integrated Marine Observing System，IMOS）大堡礁微生物基因组数据库（Great Barrier Reef Microbial Genomics Database，GBR MGD）旨在提供高质量基因组参考数据，以深化我们对微生物在珊瑚礁环境中作用的认知。该数据集依托大堡礁48个采样位点的样本采集工作，采用混合组装流程整合Illumina与Nanopore测序数据，构建了约5000个微生物基因组，并配套提供了全面的水体化学与底栖珊瑚礁调查数据。
