Plasmid engineering of aphid alarm pheromone in tobacco seedlings affects the preference of aphids.
Article in Plant signaling & behavior, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Plants producing sufficient amount of aphid alarm pheromone by expressing (E)-β-Farnesene (EβF) synthase gene may contribute to plant protection by reducing aphid populations. However, terpene biosynthesis varies among plant species and developmental stages. In the present study, volatile headspace analysis of tobacco seedlings with MaβFS1 (an EβF synthase from the Asian peppermint Mentha asiatica) failed to generate EβF. We further targeted MaβFS1 to the tobacco plastid, using a chloroplast targeting sequence, either with or without the AtFPS1 gene for the biosynthesis of the precursor farnesyl diphosphate. When both MaβFS1 and AtFPS1 genes were targeted to the chloroplast, low levels of EβF were detected in stably transformed tobacco seedlings; resulting in specific repellence of the green peach aphid, Myzus persicae. These data indicate that redirecting the EβF biosynthetic pathway from its natural cytosolic location to the chloroplast is a valid strategy. This redirecting strategy may be very useful for other crop plants that do not naturally produce EβF or other repellent volatiles.
