1 · What the graph read from it

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.

2 · The registry

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 transition from the juvenile to the mature phase during vegetative development in plants is characterized by changes in leaf shape. We show that GENERAL TRANSCRIPTION FACTOR GROUP E6 (GTE6) regulates differences in leaf patterning between juvenile and mature leaves in Arabidopsis. GTE6 encodes a novel small bromodomain-containing protein unique to plants. Mutations in GTE6 disrupt the formation of elliptical leaf laminae in mature leaves, whereas overexpression of GTE6 resulted in elongated juvenile leaves. GTE6 positively regulates the expression of ASYMMETRIC LEAVES1 (AS1), which encodes a myb-domain protein that controls proximodistal patterning of leaves. Using chromatin immunoprecipitation (ChIP) assays, we show that GTE6 is associated with the promoter and the start of the transcribed region of AS1 and up-regulates expression of AS1 through acetylation of histones H3 and H4. Genetic studies demonstrated that AS1 is epistatic to GTE6, indicating that GTE6 regulates AS1 during leaf morphogenesis. Chromatin remodeling at AS1 is a key regulatory mechanism in leaf development, which ensures the continual production of mature leaves following juvenile-adult transition, thereby maintaining the identity of the mature vegetative phase.
