Other claims from this paper (8)
- Observation Surveys of 61 wheat fields in 2017-2019 yielded 63 strains identified by 16S rRNA gene analysis as Xanthomonas spp.
- Observation Real-time PCR with species-specific primers identified 44 of the strains as X. translucens, the causal agent of bacterial leaf streak in wheat.
- Observation Multilocus sequence analysis showed these strains were most closely related to X. translucens pv. undulosa, the pathovar most commonly associated with bacterial leaf streak of wheat.
- Observation Multilocus sequence typing assigned the X. translucens strains to four sequence types, three of which were previously reported globally.
- Observation Seventeen Xanthomonas strains not belonging to X. translucens were obtained from diseased wheat leaves.
- Observation Phylogenetic analysis showed the non-translucens strains are closely related to X. prunicola and cluster with uncharacterized Xanthomonas strains from wheat in Minnesota.
- Observation In planta assays on a BLS-susceptible wheat cultivar showed X. translucens pv. undulosa strains caused brown necrosis symptoms typical of bacterial leaf streak.
- Observation In the same assays, non-translucens Xanthomonas strains elicited an atypical dry necrosis symptom on the wheat cultivar.
