1 · What the graph read from it

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.

2 · The registry

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

The interplay between vascular development and leaf development is central to the evolutionary success of vascular plants, yet the underlying mechanisms remain poorly understood. Here, we identify the RNA-binding protein JULGI1 (JUL1) as a key integrator of vascular and leaf development in Arabidopsis. JUL1 is transcribed in leaf veins, while the protein distributes throughout the leaf, where it binds G-rich regions of pri-MIR165a transcripts on the abaxial side. This interaction disrupts hairpin formation and inhibits DICER-LIKE1 (DCL1)-mediated processing, reducing miR165/166 levels. Consequently, transcript levels of their targets, the Class III homeodomain leucine zipper (HD-ZIP III), increase, reinforcing adaxial-abaxial polarity. Our findings reveal a non-cell-autonomous mechanism by which vascular-derived JUL1 modulates miRNA biogenesis to coordinate leaf patterning with vascular development.
