A chimeric cry8Ea1 gene flanked by MARs efficiently controls Holotrichia parallela.
Article in Plant cell reports, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
key messagePeanuts transformed with the synthetic cry8Ea1 gene flanked by MARs are a potentially effective control strategy against white grubs. Cry8Ea1 protein levels of the construct containing MARs were increased by 2.5 times. White grubs are now recognized as the most important pests of peanut worldwide. A synthetic cry8Ea1 gene, which was toxic to Holotrichia parallela larvae, was expressed in chimeric peanut roots using an Agrobacterium rhizogenes-mediated transformation system. The relative mRNA and protein levels of the cry8Ea1 gene were confirmed by quantitative real-time PCR and ELISA, respectively. The effects of matrix attachment regions (MARs) on the expression and activity of the cry8Ea1 gene were analyzed. The average expression level of cry8Ea1 in peanut roots was higher for the plants harboring constructs flanked by MARs from tobacco. Moreover, differing from previous studies, the synthetic cry8Ea1 gene flanked by MARs showed more variation in protein levels than mRNA levels. These composite plants containing cry8Ea1 gene flanked by MARs exhibited a high toxicity against Holotrichia parallela larvae as shown by bioassay analysis, thus offering a potential effective combination to control subterranean insects in peanuts.
