Other claims from this paper (7)
- Observation Actinoplanes missouriensis was the most inhibitory isolate and produced relatively high chitinase levels.
- Observation Actinoplanes missouriensis degraded P. tabacinum hyphae in vitro, causing plasmolysis and cell-wall lysis.
- Observation The antagonist was recovered from healthy lupin roots up to 8 weeks after inoculation.
- Intervention effect A. missouriensis significantly reduced lupin root rot severity under glasshouse conditions.
- Intervention effect The chitinase deficient Actinoplanes italicus isolate did not lyse P. tabacinum hyphae or reduce root rot.
- Intervention effect The chitinase deficient A. missouriensis mutant did not lyse P. tabacinum hyphae or reduce root rot.
- Observation The two chitinase deficient isolates colonised lupin roots similarly to the wild-type A. missouriensis isolate.
