Tn-seq identifies Ralstonia solanacearum genes required for tolerance of plant immunity induced by exogenous salicylic acid.
Article in Molecular plant pathology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Ralstonia solanacearum, the causal agent of the devastating bacterial wilt disease, is of particular interest to the scientific community. The repertoire of type III effectors plays an important role in the evasion of plant immunity, but tolerance to plant immunity is also crucial for the survival and virulence of R. solanacearum. Nevertheless, a systematic study of R. solanacearum tolerance to plant immunity is lacking. In this study, we used exogenous salicylic acid (SA) to improve the immunity of tomato plants, followed by transposon insertion sequencing (Tn-seq) analysis and the identification of R. solanacearum genes associated with tolerance to plant immunity. Target gene deletion revealed that the lipopolysaccharide (LPS) production genes RS_RS02830, RS_RS03460, and RS_RS03465 are essential for R. solanacearum tolerance to plant immunity, and their expression is induced by plant immunity, thereby expanding our knowledge of the pathogenic function of R. solanacearum LPS. SA treatment increased the relative abundance of transposon insertion mutants of four genes, including two genes with unknown function, RS_RS11975 and RS_RS07760. Further verification revealed that deletion of RS_RS11975 or RS_RS07760 resulted in reduced in vivo competitive indexes but increased tolerance to plant immunity induced by SA treatment, suggesting that these two genes contribute to the trade-off between tolerance to plant immunity and fitness cost. In conclusion, this work identified and validated R. solanacearum genes required for tolerance to plant immunity and provided essential information for a more complete view of the interaction between R. solanacearum and the host plant.
