MicroRNA-directed cleavage of Nicotiana sylvestris PHAVOLUTA mRNA regulates the vascular cambium and structure of apical meristems.

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
Leaf initiation in the peripheral zone of the shoot apical meristem involves a transition to determinate cell fate, but indeterminacy is maintained in the vascular cambium, a tissue critical to the continuous growth of vascular tissue in leaves and stems. We show that the orientation of cambial growth is regulated by microRNA (miRNA)-directed cleavage of mRNA from the Nicotiana sylvestris ortholog of PHAVOLUTA (NsPHAV). Loss of miRNA regulation in semidominant phv1 mutants misdirects lateral growth of leaf midveins and stem vasculature away from the shoot, disrupting vascular connections in stem nodes. The phv1 mutation also expands the central zone in vegetative and inflorescence meristems, implicating miRNA and NsPHAV in regulation of meristem structure. In flowers, phv1 causes reiteration of carpel initiation, a phenocopy for loss of CARPEL FACTORY/DICER LIKE1, indicating that miRNA is critical to the termination of indeterminacy in floral meristems. Results point to a common role for miRNA in spatial and temporal restriction of HD-ZIPIII mediated indeterminacy in apical and vascular meristems.
