“…The recent sequencing of eight Erwinia genomes (i.e., 3 E. amylovora, 2 Erwinia pyrifoliae, Erwinia sp., Erwinia billingiae and Erwinia tasmaniensis) (Sebaihia et al 2010;Smits et al 2010a, b;Kube et al 2008Kube et al , 2010Park et al 2011) and three genomes of the closely related genus Pantoea (i.e., P. vagans, P. agglomerans and Pantoea ananatis) (Smits et al 2010c;De Maayer et al 2010) provides a solid genomics foundation to infer the species evolution within these genera.…”
