Partitioning of the maize epigenome by the number of methyl groups on histone H3 lysines 9 and 27.

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
We report a detailed analysis of maize chromosome structure with respect to seven histone H3 methylation states (dimethylation at lysine 4 and mono-, di-, and trimethylation at lysines 9 and 27). Three-dimensional light microscopy and the fine cytological resolution of maize pachytene chromosomes made it possible to compare the distribution of individual histone methylation events to each other and to DNA staining intensity. Major conclusions are that (1) H3K27me2 marks classical heterochromatin; (2) H3K4me2 is limited to areas between and around H3K27me2-marked chromomeres, clearly demarcating the euchromatic gene space; (3) H3K9me2 is restricted to the euchromatic gene space; (4) H3K27me3 occurs in a few (roughly seven) focused euchromatic domains; (5) centromeres and CENP-C are closely associated with H3K9me2 and H3K9me3; and (6) histone H4K20 di- and trimethylation are nearly or completely absent in maize. Each methylation state identifies different regions of the epigenome. We discuss the evolutionary lability of histone methylation profiles and draw a distinction between H3K9me2-mediated gene silencing and heterochromatin formation.
