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.
