“…Multi-locus sequence analysis (MLSA) shows that the genus Erwinia is currently monophyletic for 17 accepted species, the majority of which are plant pathogens (Erwinia amylovora, E. pyrifoliae, E. piriflorinigrans, E. uzenensis, E. mallotivora, E. papayae, E. persicina, E. psidii, E. rhapontici and E. tracheiphila) (Hauben & Swings, 2005;Ló pez et al, 2011;Matsuura et al, 2012). However, the genus also encompasses epiphytes (E. billingiae and E. tasmaniensis) (Geider et al, 2006;Mergaert et al, 1999), species that may contribute to plant disease as part of multi-species microbial communities (E. toletana and E. oleae) (Buonaurio et al, 2015), and insect-associated bacteria (E. aphidicola, E. typographi and E. iniecta) (Campillo et al, 2015;Harada et al, 1997;Skrodenytė-Arbačiauskienė et al, 2012).…”
