The Ammonium Channel NOD26 is the Evolutionary Innovation that Drives the Emergence, Consolidation, and Dissemination of Nitrogen-Fixing Symbiosis in Angiosperms.

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
Increasing evidence indicates that N-fixing symbiosis has evolved several times in the N-fixing clade of angiosperms and that this evolution is driven by a single evolutionary innovation. However, the genetics of this ancestral predisposition to N-fixing symbiosis remains unclear. A natural candidate for such molecular innovation is the ammonium channel NOD26, the main protein component of the symbiosome membrane, which facilitates the plant uptake of the nitrogen fixed by symbiotic bacteria. Here, in concordance with the emergence of N-fixing symbiosis in angiosperms but not in ancestral plants, phylogenetic analysis showed that NOD26 belongs to an angiosperm-exclusive subgroup of aquaporins. Integrated genomic, phylogenetic, and gene expression analyses supported NOD26 occurrence in the N-fixing clade, the increase in the NOD26 copy number by block and tandem duplications in legumes, and the low-copy number or even the loss of NOD26 in non-legume species of the N-fixing clade, which correlated with the possibility to lose N-fixing symbiosis in legume and non-legume lineages. Metabolic reconstructions showed that retention of NOD26 in N-fixing precursor could represent an adaptive mechanism to bypass energy crisis during anaerobic stress by ammonium detoxification. Finally, we discuss the potential use of NOD26 to transfer N-fixation to non-N-fixing crops as cereals.
