Table I.
Number of gold particles in the cytosol and bacteroids of infected cells from cowpea nodules
| Treatment | Cytosol | Bacteroids |
|---|---|---|
| number of gold particles per 25 μm2 | ||
| FeSOD antibody | 6.0 ± 0.5* | 3.9 ± 0.4 |
| Non-immune serum | 1.2 ± 0.1 | 3.4 ± 0.4 |
Values are means ± se of 32 micrographs (each micrograph 25 μm2) taken from sections of three nodules incubated with FeSOD antibody or non-immune serum. Means denoted with an asterisk are significantly different (P < 0.01) from the corresponding non-immune serum according to the Fisher's F test.
