Other claims from this paper (19)
- Intervention effect Flooding decreased root nodule number from 124 to 51 per plant.
- Intervention effect Flooding with stem nodulation increased shoot dry weight regardless of rhizobial isolate.
- Intervention effect Flooding with stem nodulation decreased root dry weight regardless of rhizobial isolate.
- Observation Stem nodules attach through an aerenchymatous collar.
- Observation Large stem air spaces are continuous with nodule aerenchyma and outer cortex.
- Observation Aerenchyma and spongy tissue connect flooded and non-flooded root nodules to root cortex spaces.
- Observation Stem and root nodules were ovoid and aeschynomenoid, with infected tissue lacking interstitial uninfected cells.
- Observation Root nodules resembled stem nodules structurally, but stem nodules were generally larger.
- Intervention effect Flooded root nodules were approximately twice as large as non-flooded root nodules.
- Observation Infected root and stem nodule cells contained one or two rod-shaped bacteroids per peribacteroid unit and prominent organelles.
- Observation Infection threads occurred in root nodules but not stem nodules.
- Observation Stem and root nodule cortices had an apparent oxygen diffusion barrier of small interlocking cells.
- Observation Glycoprotein occlusion abundance appeared similar across nodule types and treatments.
- Observation Stem nodules had intracellular glycoprotein vesicles adjacent to cell walls.
- Observation Nodule exteriors had flattened-cell epidermis with occasional lenticels.
- Observation Amyloplasts were common in lower stem and hypocotyl nodules but fewer in root nodules.
- Observation Upper stem nodules had chloroplasts throughout the cortex compared with deeper submerged stem nodules.
- Observation Root nodules lacked chloroplasts.
- Observation Undifferentiated plastids occurred mainly in lower stem nodules.
