Characterization of <i>Pantoea ananatis</i> from rice planthoppers reveals a clade of rice-associated <i>P. ananatis</i> undergoing genome reduction.

ABSTRACT: Pantoea ananatis is a bacterium that is found in many agronomic crops and agricultural pests. Here, we isolated a P. ananatis strain (Lstr) from the rice planthopper Laodelphax striatellus, a notorious pest that feeds on rice plant sap and transmits rice viruses, in order to examine its genome and biology. P. ananatis Lstr is an insect symbiont that is pathogenic to the host insect and appears to mostly inhabit the gut. Its pathogenicity thus raises the possibility of using the Lstr strain as a biological agent. To this end, we analysed the genome of the Lstr strain and compared it with the genomes of other Pantoea species. Our analysis of these genomes shows that P. ananatis can be divided into two mono-phylogenetic clades (clades one and two). Th
