Histone modifications associated with drought tolerance in the desert plant Zygophyllum dumosum Boiss.
Article in Planta, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 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
Zygophyllum dumosum Boiss. is a perennial Saharo-Arabian phytogeographical element and a dominant shrub on the rocky limestone southeast-facing slopes of the Negev desert. The plant is highly active during the winter, and semideciduous during the dry summer, i.e., it sheds its leaflets, while leaving the thick, fleshy petiole green and rather active during the dry season. Being resistant to extreme perennial drought, Z. dumosum appears to provide an intriguing model plant for studying epigenetic mechanisms associated with drought tolerance in natural habitats. The transition from the wet to the dry season was accompanied by a significant decrease in nuclear size and with posttranslational modifications of histone H3 N-terminal tail. Dimethylation of H3 at lysine 4 (H3K4)--a modification associated with active gene expression--was found to be high during the wet season but gradually diminished on progression to the dry season. Unexpectedly, H3K9 di- and trimethylation as well as H3K27 di- and trimethylation could not be detected in Z. dumosum; H3K9 monomethylation appears to be prominent in Z. dumosum during the wet but not during the dry season. Contrary to Z. dumosum, H3K9 dimethylation was detected in other desert plants, including Artemisia sieberi, Anabasis articulata and Haloxylon scoparium. Taken together, our results demonstrate dynamic genome organization and unique pattern of histone H3 methylation displayed by Z. dumosum, which could have an adaptive value in variable environments of the Negev desert.
