Other claims from this paper (9)
- Observation Sweet corn developed brown water-soaked husk lesions that enlarged to 10 cm.
- Association Visible ear disease symptoms significantly affected corn market value.
- Observation Bacterial streaming and consistent bacterial isolation were observed from diseased husks.
- Observation Fatty acid profiles characterized the isolates as B. gladioli.
- Observation The bacterial 16S rRNA gene had 99.4 to 99.6% identity to B. gladioli strains.
- Observation A species-specific PCR product was obtained from both bacterial isolates.
- Intervention effect Nonwounded husks inoculated with isolate suspension also developed the same symptoms.
- Observation The pathogen was reisolated and its identity confirmed by 16S sequencing.
- Observation The authors report the first B. gladioli disease of corn in the United States.
