Arabidopsis Christchurch (AC) Leaf-Associated Bacterial Collection Dataset

This repository provides the up-to-date Arabidopsis Christchurch (AC) phyllosphere culture collection, including images of colonies for each isolate, genome-resolved taxonomic assignment, phylogeny, functional annotation, and 16S gene amplicon sequencing data. The dataset includes: Strain metadata (AC_samples.csv). Amplicon-derived ASV tables (ASV_sequences.csv). GTDB classifications (gtdbtk_classification.csv). ANI values (fastani.csv). Phylogenetic reconstruction (SpeciesTree_rooted_node_labels.txt), from OrthoFinder. CheckM completeness metrics (checkM.csv). Curated R objects and CSV representing phyloseq analysis, alpha-diversity outputs, and isolate genome features (Rdata.tar.gz). Unformatted data is included as Supplementary Materials in the corresponding publication. Images of each isolate grown on R2A-agar plates at 30°C (colonies.tar.gz). This resource supports reproducible work on Arabidopsis leaf microbiota and forms a reusable material for comparative genomics, trait mapping, and microbiome diversity analysis.
