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

Rice false smut, caused by Ustilaginoidea virens, increases the proportion of unfilled grains and reduces pollen viability in infected rice panicles. Although the fungus adopts a flower-specific infection strategy that interferes with fertilization, the underlying molecular mechanisms remain unclear. Here we show that U. virens manipulates rice floret development and immune responses during early infection by targeting host lipid signalling. We identified secreted in xylem protein 1 (Sxp1) as a secreted apoplastic effector induced under nutrient-rich conditions and during early infection. Ectopic expression of Sxp1 in rice causes near-complete spikelet sterility and markedly reduced pollen viability. Sxp1 is a key virulence factor and interacts with the lipid transfer protein LTPL113, which binds phosphatidic acid and phosphatidylserine, and is essential for pollen development and lipid-potentiated immune outputs. Sxp1 disrupts the association between LTPL113 and lipids, thereby compromising lipid-mediated immunity and floret development. Together, our findings reveal a mechanism by which U. virens hijacks lipid signalling to manipulate floret development and suppress immunity.
