“…Erwinia is one of the youngest genera of microorganisms that can cause plant disease, having diverged from Pantoea less than 1,000 years ago (Figure 2). Based on recent time-tree estimates (100), three groups of species within this genus diverged very recently: a group pathogenic on apples, pears, and other Rosaceae (including Erwinia amylovora and closely related species); a group of species that are very persistent in the environment, pathogenic on a wide range of plants, and also found in association with aphids [Erwinia aphidicola (99), Erwinia persicina (99), and Erwinia rhapontici (79)]; and a group with members found in association with guava and eucalyptus. In this latter group, E. psidii is emerging as an important pathogen of eucalyptus in Brazil (4), a region where this tree is being intensively cultivated outside of its natural range.…”

Strategies to manage plant disease—from use of resistant varieties to crop rotation, elimination of reservoirs, landscape planning, surveillance, quarantine, risk modeling, and anticipation of disease emergences—all rely on knowledge of pathogen host range. However, awareness of the multitude of factors that influence the outcome of plant–microorganism interactions, the spatial and temporal dynamics of these factors, and the diversity of any given pathogen makes it increasingly challenging to define simple, all-purpose rules to circumscribe the host range of a pathogen. For bacteria, fungi, oomycetes, and viruses, we illustrate that host range is often an overlapping continuum—more so than the separation of discrete pathotypes—and that host jumps are common. By setting the mechanisms of plant–pathogen interactions into the scales of contemporary land use and Earth history, we propose a framework to assess the frontiers of host range for practical applications and research on pathogen evolution.

“…Enterobacteriaceae was detected as the second most abundant OTU in both the imported and the domestic pollen samples. In the imported pollen, 20.09% of Enterobacteriaceae was identified as uncultured bacterium and 5.85% was Erwinia aphidocola , which is known as a pathogenic bacterium in several plants ( Luo et al, 2018 ; Marín et al, 2011 ). In contrast, in the domestic pollen most of Enterobacteriaceae was assigned as Pantoea spp.…”
