Other claims from this paper (9)

Intervention effect All isolates completely wilted eggplant and tomato test plants within 3–4 days.
Observation MLST showed high conservation with most alleles identical across isolates.
Observation Variation in ppsA and egl suggested novel alleles in three isolates.
Observation MLST grouped the isolates into six clusters.
Observation Cluster I showed high similarity, while clusters III and IV showed allelic variation.
Observation Phylotype I showed moderate genetic diversity.
Observation Phylotype II had slightly higher nucleotide diversity but reduced haplotype diversity.
Observation Phylotype III had the highest nucleotide diversity and frequent recombination.
Observation Phylotype IV showed intermediate diversity and fewer recombination events.

Factors influencing Ralstonia pseudosolanacearum infection incidence and disease development in rose plants

Jan van der Wolf; Pieter Kastelein; Leo Poleij; et al. Plant Pathology 2022. doi:10.1111/ppa.13596

Other claims from this paper (7)

Observation The three rose cultivars differed in susceptibility.
Intervention effect At 20°C, the rose strain caused hardly any symptoms over six weeks.
Intervention effect At 28°C, Armando showed typical wilt within two weeks after stem inoculation.
Intervention effect Root inoculation caused only weak atypical symptoms.
Observation Root inoculation of Armando at 10 4 cfu/ml yielded high stem-base densities in one of two experiments.
Observation Ralstonia occasionally spread from symptomatic stem-inoculated roses in rockwool slabs.
Observation Spread caused low infection incidence limited to adjacent rose plants.
