SAUR53 regulates organ elongation and apical hook development in Arabidopsis.
Article in Plant signaling & behavior, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 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
SAUR53 is a member of SAUR (Small Auxin-Up RNA) gene family of primary auxin responsive genes. In Arabidopsis, SAUR gene family is represented by 81 genes including two pseudogenes; however, the functions of most of these genes are not fully characterized yet. In the present study, we show that SAUR53 expresses throughout the plant and localizes to both plasma membrane and the nucleus. Unlike most other SAUR genes, expression of SAUR53 is not induced in response to auxin. Ectopic expression of SAUR53 results in the elongation of cells and organs, and also interferes with normal apical hook development by accelerating the hook maintenance phase. Moreover, root growth of SAUR53 overexpression seedlings is significantly insensitive to IAA and 2,4-D, while showing wild-type sensitivity to NAA, suggesting that elevated level of SAUR53 may interfere with normal auxin transport. Collectively, this study indicates that while SAUR53 positively regulates cell and organ elongation, it probably negatively regulates auxin transport in Arabidopsis.
