Genome sequence data of Caudoviricetes bacteriophage MK21 infecting Xanthomonas citri, the causative agent of citrus canker

Abstract

This dataset reports the isolation and genomic characterization of the Caudoviricetes bacteriophage MK21, a novel bacteriophage infecting Xanthomonas citri subsp. citri (XCC), collected from soil samples on Jeju Island, South Korea. The phage was isolated and enriched using double agar layer plaque assays on nutrient media. Genomic analysis revealed that the phage MK21 is a double-stranded circular DNA genome of 43,495 bp, comprising 61 genes with high coding density. The dataset includes detailed genomic information, highlighting genes related to structural components, lysis mechanisms, and DNA/RNA metabolism. Phylogenetic analysis shows a close relationship with Xanthomonas phage CP1, supporting its potential use in comparative genomic studies and the development of antibacterial agents against citrus canker. This dataset offers valuable insights for the advancement of phage therapy and sustainable agricultural practices.
