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

Plants actively recruit beneficial rhizosphere microorganisms to enhance immunity, though the molecular mechanisms are largely unclear. Here we identified a complete OsMAPK-OsWRKY pathway of rice rhizosphere Bacillus recruitment via root secretion of heptadecanoic acid upon rice blast occurrence. In field trials, enrichment of Bacillus in their rhizospheres was associated with higher disease resistance of rice. Integrated omics analyses demonstrated a strong correlation between the activation of the OsMKK4-OsMPK6 cascade and Bacillus recruitment. Loss-of-function mutants of OsMKK4 and OsMPK6 reduce rhizosphere Bacillus abundance by 82% and 79%, respectively. As the substrates of OsMPK6, OsWRKY24/53/70 transcription factors activate OsKCS2, which encodes a β‑ketoacyl-CoA synthase involved in heptadecanoic acid biosynthesis. Mutations of OsWRKY24/53/70 or OsKCS2 reduce root-secreted heptadecanoic acid by 15-28% and impair Bacillus colonization. Heptadecanoic acid application recapitulated Bacillus recruitment and disease resistance. Collectively, our results demonstrate that the MAPK pathway regulates heptadecanoic acid synthesis, which controls Bacillus recruitment as well as rice blast disease resistance.
