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

Strawberry tree (Arbutus unedo, Ericaceae) is an evergreen tree with a circum-Mediterranean distribution. It has a great ecological and economic importance as a source of bioactive compounds with industrial applications and for fruit production. This study aims to characterize the fungi microbiome of this forestry species in order to develop biological control strategies in the increasing orchard production area. For this purpose, fungi endophytes were isolated from wild strawberry tree plants, and a molecular identification was carried out. In vitro assays were carried out to evaluate and characterize the antagonism of some endophytes. Among the several fungi endophytes isolated from strawberry tree (a total of 53 from 20 genera), a Trichoderma atroviride strain proved to have antagonism effect against several phytopathogens, including Alternaria alternata, Botrytis cinerea, Glomerella cingulata, and Mycosphaerella aurantia. This antagonism was particularly effective against Phytophthora cinnamomi, causing a reduction in growth of about 80% on this invasive oomycete. An enzymatic assay revealed the production of several enzymes by T. atroviride, such as cellulases, chitinases, glucosidases, alkaline phosphatases, and proteases, which is one of the several mechanisms known to be involved on Trichoderma biological control ability. The enzymatic activity, in particular that of cell wall-degrading enzymes, was accentuated when in a dual culture with P. cinnamomi. The production of serine proteases, aspartyl proteases, metalloproteases, and cysteine proteases was also detected in an experiment carried out in liquid medium, suggesting the involvement of these proteases on Trichoderma mycoparasitism mechanisms. Finally, in a three-way interaction with in vitro strawberry tree plants, the T. atroviride strain identified on this study (Au50) was able to protect the plants against P. cinnamomi, thus proving its potential as a biological control agent.
