Metabolic engineering and potential functions of proanthocyanidins in poplar.
Article in Plant signaling & behavior, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
Poplar (Populus spp.) is a widely distributed tree genus of significant economic and ecological importance. Poplar trees accumulate proanthocyanidins (PAs) in leaves, roots, and a variety of other tissues. Damage to leaves by insects causes a rapid accumulation of PAs, both at the site of damage and distally in undamaged leaves. This rapid PA accumulation is mediated by the activation of genes encoding enzymes involved in PA synthesis. PAs have been hypothesized to deter insect feeding and reduce the nutritive value of poplar leaf tissue, but experimental evidence supporting a role for PAs as an effective inducible defense against herbivores is lacking. Our recent paper described the identification of a MYB gene that regulates the PA pathway under multiple stress conditions, and we used this gene to constitutively activate the PA pathway in poplar. Here we describe observations that suggest that poplar PAs may have roles besides insect defense, for example, responses to UV light. The PA-modified trees will be a useful tool for analyzing the biological roles of PAs in this important model tree.
