Other claims from this paper (5)
- Intervention effect NA30 inoculation responses in F2 crosses ranged from ineffective to fully effective.
- Association The other parent variety influenced the proportion of ineffective plants in F2 populations.
- Mechanism The authors attributed individual differences to segregation of one major and several modifying genes.
- Observation One other bacterial strain showed an NA30-like response pattern.
- Observation A second strain produced a different form of host by strain specific ineffectiveness.
