Complete genome sequence of Erwinia pyrifoliae strain YKB12327, isolated from an apple tree in Korea

Abstract

Erwinia pyrifoliae, the Gram-negative bacterial pathogen responsible for black shoot blight, exhibits symptoms similar to E. amylovora (fire blight), though with distinct molecular characteristics. Given its prevalence primarily in South Korea and the availability of only nine assembled genomes, there is a lack of high-quality genome sequences and annotated genetic information for E. pyrifoliae. We present the sequencing and assembly of a Korean E. pyrifoliae strain, YKB12327, isolated from a diseased apple tree branch, using a combination of long Oxford Nanopore Technologies and short Illumina sequence reads. This genome comprises a circular chromosome and three plasmid sequences, totaling 4,061,634 bp. Annotation of YKB12327 identifies 3123 coding sequence protein-coding genes, 22 rRNA genes (5S, 16S, and 23S), and 76 tRNA genes. Our sequence data will enrich the current E. pyrifoliae genome resources and facilitate in understanding its evolution, diversity and structural variations, as well as the molecular basis of pathogenesis.
