Other claims from this paper (9)
- Intervention effect Serratia pretreatment reduced cucumber seedling disease after Pythium inoculation relative to untreated plants.
- Intervention effect Bacterized seedlings restricted fungal colonization to outer root tissues.
- Association Restricted colonization correlated with callose rich wall appositions and osmiophilic material.
- Observation Pythium cell walls were regularly labeled by beta-1,4-exoglucanase despite their osmiophilic coating.
- Observation Osmiophilic material infiltrated invading hyphae and formed an internal wall coating or polymorphic droplets.
- Observation Wall appositions contained callose, pectin and cellulose.
- Observation Wall apposition cores contained glucosides, lipids and phenolics.
- Observation Wall appositions also contained galactose residues among minor polysaccharides.
- Mechanism The authors conclude that Serratia sensitizes cucumber to faster, more effective barriers against Pythium.
