Determination of histone epigenetic marks in Arabidopsis and tomato genes in the early response to Botrytis cinerea.
Article in Plant cell reports, 2018. 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
key messageDetermination of histone epigenetic marks in Arabidopsis and tomato genes in the early response to Botrytis cinerea may contribute to find biomarkers of the early detection of this devastating pathogen. Recent studies have linked epigenetic modifications with plant responses to biotic stresses. Information about specific histone marks upon necrotrophic pathogens is scarce. Here we wondered whether the altered responsiveness of specific genes in plants infected with Botrytis cinerea was associated with changes in chromatin structure. We performed a chromatin immunoprecipitation analysis that obtained differential epigenetic signature of activating marks H3K4me3, H3K9ac, and the repressor one H3K27me3 on both the promoter and the body of the highly induced PR1 in Arabidopsis plants infected with B. cinerea at 24 and 33 h after inoculation. We also determined the histone marks' profile in two differentially expressed genes in response to B. cinerea, as well as to oxidative stress, given its relevance in this infection. These are both the induced CYP71A13, which encodes a cytochrome P450 involved in camalexin synthesis, and is essential against this necrotroph and the repressed EXL7 (Exordium-like 1). We also adapted our protocol in tomato plants infected with B. cinerea. At 24 hpi, H3K4me3 level increased on the promoter and at different locations of the body of the genes induced upon B. cinerea, including DES (divinyl ethyl synthase), LoxD (lipoxygenase D), DOX1 (α-dioxygenase 1), PR2 (pathogenesis-related protein2), WRKY53 and WRKY33. The histone modifications determined herein will allow future studies on epigenetic marks and their transgenerational inheritance in plants infected with B. cinerea. In addition, the analyzed genes are potential biomarkers of B. cinerea infection that could contribute to its early detection in tomato and related crops.
