Use of RNAi as a preliminary tool for screening putative receptors of nematicidal toxins from Bacillus thuringiensis.

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
Bacillus thuringiensis is a potential control agent for plant-parasitic nematodes. Nematode intestinal receptors for Cry21-type toxins are poorly known. Therefore, a strategy was tested as a primary screening tool to find possible Cry toxin receptors, using a nematicidal Bt strain and the RNAi technique on Caenorhabditis elegans. Six genes encoding intestinal membrane proteins were selected (abt-4, bre-1, bre-2, bre-3, asps-1, abl-1) as possible targets for Cry proteins. Fractions of each selected gene were amplified by PCR. Amplicons were cloned into the L4440 vector to transform the E. coli HT155 (DE3) strain. Transformed bacteria were used to silence the selected genes using the RNAi feeding method. Nematodes with silenced genes were tested with the Bt strain LBIT-107, which harbors the nematicidal protein Cry21Aa3, among others. Results indicated that nematodes with the silenced abt-4 gene were 69.5% more resistant to the LBIT-107 strain, in general, and 79% to the Cry21Aa3 toxin, specifically.
