The E3 ubiquitin ligase HOS1 is involved in ethylene regulation of leaf expansion in Arabidopsis.
Article in Plant signaling & behavior, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
Ethylene regulates a variety of physiological processes, such as flowering, senescence, abscission, and fruit ripening. In particular, leaf expansion is also controlled by ethylene in Arabidopsis. Exogenous treatment with ethylene inhibits leaf expansion, and consistently, ethylene insensitive mutants show increased leaf area. Here, we report that the RING finger-containing E3 ubiquitin ligase HIGH EXPRESSION OF OSMOTICALLY RESPONSIVE GENES 1 (HOS1) regulates leaf expansion in an ethylene signaling pathway. The HOS1-deficient mutant showed reduced leaf area and was insensitive to ethylene perception inhibitor, silver thiosulfate (STS). Accordingly, genes encoding ethylene signaling components were significantly up-regulated in hos1-3. This study demonstrates that the HOS1 protein is involved in ethylene signal transduction for the proper regulation of leaf expansion possibly under environmentally stressful conditions.
