1 · What the graph read from it

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.

2 · The registry

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

We sought to determine whether Streptomyces albidoflavus CFFSUR-B12, Serratia marcescens CFFSUR-B2, and Trichoderma sp. CFFSUR-A21-strains recognised for their antagonistic capacity against tropical phytopathogenic fungi-could colonise the roots of and induce the expression of key induced systemic resistance (ISR) genes in Arabidopsis thaliana Col-0. These strains employ different mechanisms of direct antagonistic action against phytopathogenic fungi, so if they are capable of activating ISR, they would activate it in different ways. The antagonistic activity against Colletotrichum M07-C2 or M10-F2 strains was determined in dual-culture assays, where S. albidoflavus CFFSUR-B12 (75%), Trichoderma sp. CFFSUR-A21 (70%) and S. marcescens CFFSUR-B2 (46%) inhibited mycelial growth. Strains were inoculated separately in the roots of A. thaliana Col-0 to study root colonisation and activation of ISR in leaves. PR1 and PDF1.2 expression (as markers for the expression of the salicylic acid and the ethylene/jasmonic-acid signalling pathways, respectively) were monitored by RT-qPCR in leaves. Serratia marcescens CFFSUR-B2 colonised the rhizoplane and endorhizosphere, whereas S. albidoflavus CFFSUR-B12 and Trichoderma sp. CFFSUR-A21 only colonised the rhizoplane. Serratia marcescens CFFSUR-B2 and Trichoderma sp. CFFSUR-A21 induced co-expression of PR1 and PDF1.2 at 48 h, while S. albidoflavus CFFSUR-B12 induced only PDF1.2 expression at 24 h. Still, the pathogenic Colletotrichum M07-C2 or M10-F2 strains only induced the expression of PR1 after 72 h. These findings reveal new avenues for research into plant disease management in the humid tropics.
