LOT regulates TGN biogenesis and Golgi structure in plants.
Article in Plant signaling & behavior, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Trans-Golgi Network (TGN) is an essential organelle in eukaryotic cells. It acts not only as the sorting station of trafficking cargoes, but also as a signaling hub. In plant cells, TGN simultaneously takes the role of early endosome (EE) and contributes to the endocytic recycling. We recently characterized the first Golgi-localized protein Loss of TGNs (LOT) that is critical for TGN biogenesis and demonstrated its role during pollen tube growth in Arabidopsis. We also showed that the homozygous lot plant is dwarf and smaller than the wild type plant. As LOT is a single-copy gene and shows ubiquitous expression pattern, knowledge of its role in vegetative tissues, besides the pollen, is important for understanding the regulation of TGN/EE dynamics and signaling in plant development. Here, in this short communication, we present data to show that LOT also regulates TGN formation and Golgi structure in root meristem cells, and is critical for the elongation of hypocotyl and stamen filament.
