This dataset contains the raw and processed data supporting the manuscript “Genomic and phenotypic characterization of novel jumbo and small bacteriophages infecting Xanthomonas hortorum pv. vitians: Toward a phage-based biocontrol strategy" *Correspondence: Franck Bertolla, franck.bertolla@univ-lyon1.fr; Anaelle Baud, anaelle.baud@univ-lyon1.fr It includes: Host range analysis (EOP matrices and images) PFU images Adsorption kinetics data Bioscreen data for growth curves and multiplicity of infection (MOI) effects One-step growth curve (OSGC) data Stability assays under abiotic stress conditions (pH, temperature, UV) Transmission electron microscopy (TEM) images Whole-genome sequencing data for phages ΦXhv-2, ΦXhv-5, ΦXhv-7, ΦXhv-12, ΦXhv-15, ΦXhv-16, ΦXhv-18, and ΦXhv-28 (raw reads, FASTQ format) Most files are provided as Excel spreadsheets (.xlsx) or ZIP archives, compatible with R and other statistical software. Raw sequencing data are supplied as compressed FASTQ files.All datasets correspond to the analyses described in the main text and supplementary materials of the publication.
