Other claims from this paper (8)
- Observation The F. oxysporum population associated with tomato comprised 26 sequence types.
- Observation Two sequence types represented nearly two-thirds of the F. oxysporum isolates from tomato.
- Observation Sequence types of F. oxysporum from tomato were placed in different phylogenetic clades.
- Observation Endophytic F. oxysporum isolates from tomato were not monophyletic.
- Observation Multiple sequence types were found in every tomato plant, averaging 4.2 per plant.
- Association F. oxysporum population compositions differed between the two tomato fields.
- Association F. oxysporum population compositions did not differ between soil samples within each field.
- Association A certain degree of differentiation was observed between F. oxysporum populations associated with different tomato cultivars, suggesting an effect of host genotype.
