Epiphytic Bacterium, Erwinia ananas, Commonly Isolated from Rice Plants and Brown Planthoppers (Nilaparvata lugens) in Hopperburn Patches

Pantoea ananatis: an unconventional plant pathogen

“…The epidemiology of plant diseases caused by P. ananatis on different hosts is relatively unknown. What has been established is that the pathogen enters its host through flowers (Hasegawa et al ., 2003; Serrano, 1928) and/or wounds created by feeding insects (Gitaitis et al ., 2003; Watanabe et al ., 1996; Wells et al ., 2002), mechanical injury (Serrano, 1928) and plant to plant contact during high winds (Azad et al ., 2000; Cother et al ., 2004). The development of brown hopper burn symptoms on rice was found to be accelerated when P. ananatis was present on the leaf surfaces.…”

Pantoea ananatis: genomic insights into a versatile pathogen

“…In these areas, this bacterium has an exceptional lifestyle, as it is not only associated with plants, but is also frequently isolated from a wide range of environmental sources. As a plant pathogen, it causes severe losses of many agronomic crop and tree species, such as maize (Goszczynska et al ., ), rice (Watanabe et al ., ), onion (Gitaitis et al ., ) and Eucalyptus (Coutinho et al ., ). Pantoea ananatis is also frequently isolated from a wide range of plant hosts as an epiphyte or endophyte, where it exists as a commensal without causing any disease symptoms (Coutinho and Venter, ).…”

Identification of Ice-Nucleating ActivePseudomonas fluorescensStrains for Biological Control of Overwintering Colorado Potato Beetles (Coleoptera: Chrysomelidae)

“…Because P. syringae is a common epiphytic bacterium (i.e., capable of living on plant surfaces) (Hirano and Upper 1990), it may be readily ingested along with foliage and may be incidentally isolated when culturing beetle gut ßora. Nonetheless, it has been shown that some epiphytic bacteria can colonize the gut of some insects (Takahashi et al 1995;Watanabe et al 1996Watanabe et al , 1998, suggesting that establishment of an introduced bacteria in an insect gut varies with the species and strain of bacterium and the insect host. Insect gut conditions (i.e., pH, enzymes present, native bacterial ßora) vary between species and may limit the growth of an introduced bacterial strain.…”
