Virulence assay of putative CS mutants on tobacco leaf explants
| Strain | Mean no. of tumors/explanta |
|---|---|
| Δ1392 | 2.0 ± 0.3 |
| Δ4851 | 4.4 ± 0.2 |
| Δ5306 | 4.3 ± 0.2 |
| Δ5307 | 3.8 ± 0.2 |
| Wild type (C58) | 4.5 ± 0.2 |
| Δ1392 with virG(Con) | 4.0 ± 0.2 |
| A136 | 0 ± 0 |

This assay was carried out as described in Materials and Methods using 40 tobacco leaf explants. Δ4851, Δ 5306, and Δ5307 have deletions in genes that were also annotated as CS. The scale of 0 to 5 takes into account both the numbers of tumors and their sizes.
