Whole-genome sequencing of Erwinia amylovora strains from México detects SNPs in rpsL conferring streptomycin resistance and in the avrRpt2 effector altering host interactions

摘要

We report draft genome sequences of three Mexican Erwinia amylovora strains. A novel plasmid, pEA78, was identified. Comparative genomics revealed an rpsL chromosomal mutation conferring high-level streptomycin resistance in two strains. In the effector gene avrRpt2, a single nucleotide polymorphism was detected that overcomes fire blight disease resistance in Malus × robusta 5.
