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

Momilactones from rice have allelopathic activity, the ability to inhibit growth of competing plants. Transferring momilactone production to other crops is a potential approach to combat weeds, yet a complete momilactone biosynthetic pathway remains elusive. Here, we address this challenge through rapid gene screening in Nicotiana benthamiana, a heterologous plant host. This required us to solve a central problem: diminishing intermediate and product yields remain a bottleneck for multistep diterpene pathways. We increased intermediate and product titers by rerouting diterpene biosynthesis from the chloroplast to the cytosolic, high-flux mevalonate pathway. This enabled the discovery and reconstitution of a complete route to momilactones (>10-fold yield improvement in production versus rice). Pure momilactone B isolated from N. benthamiana inhibited germination and root growth in Arabidopsis thaliana, validating allelopathic activity. We demonstrated the broad utility of this approach by applying it to forskolin, a Hedgehog inhibitor, and taxadiene, an intermediate in taxol biosynthesis (~10-fold improvement in production versus chloroplast expression).
