Rahnella perminowiae sp. nov., Rahnella bonaserana sp. nov., Rahnella rivi sp. nov. and Rahnella ecdela sp. nov., isolated from diverse environmental sources, and emended description of the genus Rahnella Open
Bacteria isolated from onion bulbs suffering from bacterial decay in the United States and Norway were previously shown to belong to the genus Rahnella based on partial housekeeping gene sequences and/or fatty acid analysis. However, many …
<i>Rahnella</i> spp. are commonly isolated from onion ( <i>Allium cepa</i> ) bulbs and are weakly pathogenic Open
While Rahnella strains are commonly found within field-grown onions and they are able to cause mild symptoms, the economic impact of Rahnella-associated symptoms remains unclear.
<i>HIPM</i> Is a Susceptibility Gene of <i>Malus</i> spp.: Reduced Expression Reduces Susceptibility to <i>Erwinia amylovora</i> Open
Fire blight, a devastating disease caused by the bacterium Erwinia amylovora, is a major threat to apple crop production. To improve our understanding of the fire blight disease and to identify potential strategies to control the pathogen,…
Center Rot of Onion (<i>Allium cepa</i>) Caused by <i>Pantoea ananatis</i> Requires <i>pepM</i>, a Predicted Phosphonate-Related Gene Open
Pantoea ananatis, a cause of center rot of onion, is problematic in the United States and elsewhere. The bacterium lacks disease determinants common to most other bacterial pathogens of plants. A genomic island containing the gene pepM was…
Lactic Acid Bacteria Cause a Leaf Blight and Bulb Decay of Onion (<i>Allium cepa</i>) Open
Several members of the lactic acid bacteria group were isolated from diseased onion plants and bulbs. Based on growth characteristics and sequence analysis of 16S rRNA and rpoA genes, the strains were identified as Lactococcus lactis, Lact…
