Identification of Drivers Microorganisms in Cacao Culture Soil. A Retrospective Study
摘要
Soil microbial communities play a crucial role in agricultural sustainability. This study employs a retrospective analysis of publicly available metabarcoding datasets to identify microbial drivers influencing cacao soil health. Using data from six NCBI Bioprojects, we examined bacterial communities across different environmental conditions and geographical locations. Bioinformatics pipelines, including QIIME2 and PM2RA, were utilized to assess taxonomic composition and microbial interactions. Our findings highlight significant microbial diversity variations across environments such as cultivated fields, forests, and greenhouses. Beta-diversity analysis revealed strong distinctions between microbial communities based on location and land use type. Microbial drivers, including Sphingomonas daechungensis, Horticoccus luteus, Pedomicrobium, Usitatibacter, and Occallatibacter, were identified as modulators of soil microbial balance. These taxa influence soil nutrient cycling, pathogen suppression, and plant resilience, with potential applications in bioremediation and sustainable cacao farming. Our results demonstrate that microbial co-occurrence netshift significantly based on soil conditions, with PM2RA analysis filtering interactions below a co-PM threshold of 0.1. This research emphasizes the importance of leveraging microbial bioindicators to monitor soil health and optimize cacao productivity. Understanding these microbial interactions offers promising avenues for enhancing crop yield, disease resistance, and environmental sustainability in the global cacao industry.
