Distribution of gold particles in various alfalfa nodule cells after immunolabeling with affinity-purified NADH-GOGAT antibodies
| Cell Type | Individual Profilesa | Labeling Density |
|---|---|---|
| no. | gold particles/0.25 μm2 | |
| Cytosol | 30 | 0.13 ± 0.05 |
| Intercellular space | 30 | 0.29 ± 0.09 |
| Cell wall | 30 | 0.36 ± 0.91 |
| Mitochondria | 30 | 0.13 ± 0.05 |
| Bacteroids | 30 | 0.14 ± 0.04 |
| Amyloplasts of infected cells | 30 | 3.5 ± 0.24 |
| Amyloplasts of uninfected cells | 30 | 1.2 ± 0.92 |
All the tissues were from effective N2-fixing nodules. Labeling density values are means ± se.
a
Ten microscope fields from each of three individual nodules were examined.
