Longer uncommon polyamines have a stronger defense gene-induction activity and a higher suppressing activity of Cucumber mosaic virus multiplication compared to that of spermine in Arabidopsis thaliana.
Article in Plant cell reports, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
key messageOur work suggests that long chain polyamines and their derivatives are potential chemicals to control viral pathogens for crop production. Previously we showed that two tetraamines, spermine (Spm) and thermospermine (T-Spm), induce the expression of a subset of defense-related genes and repress proliferation of Cucumber mosaic virus (CMV) in Arabidopsis. Here we tested whether the longer uncommon polyamines (LUPAs) such as caldopentamine, caldohexamine, homocaldopentamine and homocaldohexamine have such the activity. LUPAs had higher gene induction activity than Spm and T-Spm. Interestingly the genes induced by LUPAs could be classified into two groups: the one group was most responsive to caldohexamine while the other one was most responsive to homocaldopentamine. In both the cases, the inducing activity was dose-dependent. LUPAs caused local cell death and repressed CMV multiplication more efficiently as compared to Spm. LUPAs inhibited the viral multiplication of not only avirulent CMV but also of virulent CMV in a dose-dependent manner. Furthermore, LUPAs can activate the systemic acquired resistance against CMV more efficiently as compared to Spm. When Arabidopsis leaves were incubated with LUPAs, the putative polyamine oxidase (PAO)-mediated catabolites were detected even though the conversion rate was very low. In addition, we found that LUPAs induced the expression of three NADPH oxidase genes (rbohC, rbohE and rbohH) among ten isoforms. Taken together, we propose that LUPAs activate two alternative reactive oxygen species evoked pathways, a PAO-mediated one and an NADPH-oxidase-mediated one, which lead to induce defense-related genes and restrict CMV multiplication.
