Other claims from this paper (9)
- Observation Strain BH72 preferentially entered root elongation and differentiation zones and colonized root interiors.
- Observation Bacteria also colonized stelar tissue and were found in xylem.
- Observation Azoarcus showed no evidence of residence in living plant cells, while penetrated cells appeared destroyed.
- Observation A pathogenicity test found no evidence that Azoarcus strains are phytopathogenic on tobacco leaves.
- Intervention effect BH72 inoculation significantly promoted rice seedling growth versus control.
- Intervention effect Adding malate reversed the BH72 growth promotion.
- Intervention effect The nifK mutant produced the same rice growth response, suggesting N2 fixation was uninvolved.
- Observation Rice seedling protein extracts gave no indication of nitrogenase.
- Observation PCR and immunoblotting indicated systemic rice colonization by BH72, probably through vessels.
