Barley tolerance of Russian wheat aphid (Hemiptera: Aphididae) biotype 2 herbivory involves expression of defense response and developmental genes.
Article in Plant signaling & behavior, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
The Russian wheat aphid, Diuraphis noxia (Kurdjumov), is an invasive insect pest that causes serious yield losses in bread wheat, Triticum aestivum L., durum wheat, T. turgidum L and barley, Hordeum vulgare L. Successful management of D. noxia has been achieved through resistant varieties via plant antixenosis (aphid non-preference), antibiosis (reduced aphid growth or fecundity), tolerance (plant compensatory growth after aphid feeding), or a combination of each. Previous phenotyping experiments revealed that plants of the variety Stoneham resist D. noxia damage via tolerance. In the present study, genes involved in upstream regulation of jasmonic acid (JA), salicylic acid (SA), ethylene (ET), auxin (AUX) and abscisic acid (ABA) biosynthetic pathways were monitored using qRT-PCR in Stoneham and susceptible Otis barley plants after D. noxia biotype 2 feeding. Results indicate that D. noxia tolerance in Stoneham plants is related to greater constitutive expression of JA-, ET- and AUX-biosynthetic pathway genes than in susceptible Otis plants, suggesting the possibility of immediate plant adjustments due to the stress of D. noxia feeding. There was limited induction of genes in the ET-(ACCS) and IAA (TDC) pathways in Stoneham tissues after D. noxia feeding. JA pathway genes upregulated in Otis tissues after D. noxia infestation failed to successfully defend Otis plants. AUX and ABA transcripts in Otis may be associated with developmental collapses resulting from source and sink adjustment failures.
