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

Plant triterpenoids are a diverse group of secondary metabolites with wide distribution, high chemical diversity and interesting pharmacological and antimicrobial properties. The first step in the biosynthesis of all triterpenoids is the cyclization of the 2,3-oxidosqualene precursor, catalyzed by oxidosqualene cyclases (OSCs), which have characteristic product specificities. Biosynthesis and functions of pentacyclic triterpenes have been poorly studied in grapevine. In this study, we first investigated the profile of triterpenoids present in leaf cuticular waxes from eight Vitis vinifera cultivars cultivated in the Upper Rhine Valley. Further quantification of triterpenoids showed that these cultivars can be divided into two groups, characterized by high levels of lupeol (e.g., Pinot noir) or taraxerol (e.g., Gewurztraminer) respectively. We further analyzed the OSC family involved in the synthesis of pentacyclic triterpenes (called VvTTPSs) in the sequenced V. vinifera 40024 genome and found nine genes with similarity to previously characterized triterpene synthases. Phylogenetic analysis further showed that VvTTPS1-VvTTPS3 and VvTTPS5-VvTTPS9 belong to the β-amyrin synthase and multifunctional triterpene synthase clade, whereas VvTTPS10 belongs to the lupeol synthase clade. We studied the expression of several members of the VvTTPS family following biotic and abiotic stresses in V. vinifera 40024 as well as in the eight healthy cultivars. This study further revealed that one candidate gene, VvTTPS5, which does not belong to the lupeol synthase clade, is highly expressed in lupeol-rich cultivars. VvTTPS3, VvTTPS5, VvTTPS6, VvTTPS7 and VvTTPS10 were highly upregulated by UV stress, but only VvTTPS3, VvTTPS5, VvTTPS6 and VvTTPS10 were upregulated following downy mildew and gray mold infections respectively. These results suggest differential roles of VvTTPS against environmental stresses in grape leaves.
