Recombination activity of RAS1 in heteromolecular and mixed hetero- and homomolecular systems
| BMV mutant | Genomic RNA | Infectivitya | Number of analyzed lesions | Number of recombinants | Recombination frequencyb (%) |
|---|---|---|---|---|---|
| MH-BMV | wtRNA1 wtRNA2 MagH-RNA3 | 18 (±2) | 40 | 0 | 0 |
| M1-BMV | wtRNA1 wtRNA2 Mag1-RNA3 | 19 (±2) | 40 | 40 | 100 |
| MatH-BMV | wtRNA1 wtRNA2 MatH-RNA3 | 17 (±2) | 40 | 34 | 85 |
| MatNH-BMV | wtRNA1 wtRNA2 MatNH-RNA3 | 18 (±2) | 40 | 38 | 95 |
aInfectivity was defined as the average number of lesions per leaf.
bRecombination frequency was defined as the ratio between the number of lesions that developed recombinants and the total number of analyzed lesions.
