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

Acylsugars are structurally diverse specialized metabolites secreted by glandular trichomes of Solanaceae plants and play a crucial role in defense against herbivores and pathogens. However, the mechanism underlying acylsugar secretion remains unclear. This study identifies and characterizes the plasma membrane ATP-binding cassette (ABC) transporter Sl-ABCB5 as a key component mediating acylsugar transport in trichome secretory cells of cultivated tomato (Solanum lycopersicum). Using CRISPR-Cas9-generated Sl-ABCB5 knockout mutants, we observed a dramatic reduction in trichome acylsugar accumulation, accompanied by increased susceptibility to western flower thrips (Frankliniella occidentalis). In vitro transport assays using membrane vesicles and protoplasts confirmed the ability of Sl-ABCB5 to transport acylsugars. Furthermore, virus-induced gene silencing and CRISPR-mediated knockout of ABCB5 orthologs in wild tomato (Solanumpennellii) and black nightshade (Solanum nigrum) demonstrated functional conservation of this transporter across Solanaceae species. Together, these findings reveal a conserved acylsugar transport mechanism and establish ABCB5 as a promising target for engineering enhanced insect resistance in Solanaceae crops.
