Abstract

Erwinia mallotivora is one of the most important bacterial pathogens of papaya and causes bacterial crown rot disease in the Philippines. In this paper, we present the draft genome sequences of six Philippine E. mallotivora isolates to provide insights into the genes involved in host–pathogen interactions and compare their genomes to other Erwinia species. The genomes were sequenced using Illumina Miseq platform. The draft whole-genome assemblies of the E. mallotivora isolates are composed of 36–64 contigs with N50 value ranging from 285 to 332 kbp and cover 96.2–100% of the estimated genome size. Structural genome annotation of these assemblies has predicted 4489–4749 protein-coding genes. Comparative genomic analysis using orthologous gene sets led to the identification of conserved genes within the genus and species-specific gene orthologous groups, which collectively provide a baseline for functional genomic studies to determine genes affecting virulence and host specificity. Secreted proteins of E. mallotivora were also predicted and characterized to unravel putative genes involved in plant–pathogen interactions. This study provides the first draft whole-genome sequences of Philippine isolates of E. mallotivora, thus expanding the genomic knowledge for this species in comparison with other members of the genus Erwinia.
