Other claims from this paper (15)
- Intervention effect Mn concentrations from 6.6 to 50 microM did not affect shoot, root and nodule mass in either soybean genotype at either Fe concentration.
- Intervention effect Mn concentrations from 6.6 to 50 microM did not affect leaf and nodule ureide concentration in either soybean genotype at either Fe concentration.
- Intervention effect Mn concentrations of 70 and 90 microM hindered growth and nodulation of the Biloxi soybean genotype.
- Intervention effect Mn concentrations of 70 and 90 microM did not result in visible toxicity symptoms in soybean.
- Intervention effect An Mn concentration of 0.3 microM was deleterious to growth and nodulation in both soybean genotypes.
- Intervention effect An Mn concentration of 0.3 microM caused major alterations in the ultrastructure of chloroplasts, nuclei and mitochondria in soybean, regardless of Fe concentration.
- Observation In genotype PI227557, leaf cells showed a proliferation of Golgi apparatus and endoplasmic reticulum in the cytoplasm.
- Observation Soybean nodules showed disrupted symbiosomes lacking poly-beta-hydroxybutirate grains.
- Observation Bacterial division in soybean nodules was arrested.
- Observation At 15 microM Fe, ferritin-like crystals formed in the chloroplasts of PI227557 plants.
- Association Leaf Fe and Mn concentrations were antagonistic in soybean.
- Observation Leaf values of both Fe and Mn were higher in genotype PI227557.
- Observation Genotype PI227557 showed a greater capacity than Biloxi for Mn and Fe accumulation under most nutrient treatments.
- Association No detectable relationship between Fe or Mn and zinc, phosphorus or copper concentrations in soybean leaves.
- Recommendation Genotype PI227557 is a useful genetic resource for developing soybean cultivars for growth on low nutrient soils.
