title: Biogeography influences plant-microbe interactions and natural soil suppressiveness to black root rot disease of tobacco

description: Biogeography influences natural soil suppressiveness to black root rot disease of tobacco

This repositery accompanies the submitted manuscript "Biogeography influences natural soil suppressiveness to black root rot disease of tobacco". It contains the processed data of tobacco plant and soil metabolomics and tobacco rhizosphere metagenomics and amplicon sequencing and the scripts used for analyzing the data. The data and scripts are also presented in the GitLab https://gitlab.in2p3.fr/alix.catry/sps_tobacco/ hosted at the IN2P3 in Lyon. The raw genomic data used in this study are available under BioProject number PRJNA1224598, which comprises raw reads from metagenomic sequencing of the tobacco rhizosphere and raw reads from 16S and ITS amplicon sequencing of the tobacco rhizosphere.
