Other claims from this paper (12)
- Observation Ammophila arenaria contains nitrogen-fixing bacteria in Oregon.
- Observation Elymus mollis contains nitrogen-fixing bacteria in Oregon.
- Observation Ammophila arenaria stem and rhizome tissue has acetylene reduction activity and bacterial populations of 105 to 106 cfu/g fresh weight.
- Observation Elymus mollis stem and rhizome tissue has acetylene reduction activity and bacterial populations of 105 to 106 cfu/g fresh weight.
- Observation Pseudomonads were the most common microorganisms on initial isolation plates.
- Observation Burkholderia sp. strain Aa1 reduced acetylene with maximum liquid-medium activity at 2% oxygen.
- Observation Burkholderia sp. strain Aa1 had maximum acetylene-reduction activity on solid medium at 10% oxygen.
- Observation Nitrogenase antibody immunolocalization labeled stem and rhizome cell walls in Ammophila arenaria.
- Observation Nitrogenase antibody immunolocalization labeled stem and rhizome cell walls in Elymus mollis.
- Observation A nitrogen-fixing association was detected in Uniola paniculata.
- Observation A nitrogen-fixing association was detected in Ammophila brevigulata.
- Mechanism Endophytic diazotrophic bacteria may contribute to dune grass success on nutrient-poor sand.
