The pathogen effector BcSSP2 suppresses the NPC phase separation to facilitate Botrytis cinerea infection.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Biomolecular phase separation-mediated immunity was recently uncovered as an important strategy of plants and animals for their survival in the challenging environment. Effectors are powerful weapons evolved by pathogens to overcome host defense response for effective infection. However, plant pathogen effectors were rarely identified to suppress the phase separation-mediated host defense response. Here, we report a pathogen effector that disrupts phase separation process in host cells to suppress host defense response and facilitate pathogen infection. We identify a host-internalized effector protein BcSSP2 from a disastrous pathogen Botrytis cinerea targets the central barrier of plant nuclear pore complex (NPC). BcSSP2 disrupts the phase separation of NUP62 and attenuates phase separation-dependent nuclear transport of immune regulator MPK3 to suppress plant defense response for effective pathogen infection. Intriguingly, BcSSP2 homologs are widely distributed among necrotrophic ascomycetes and also interfere with NUP62 phase separation, suggesting that disrupting plant NPC phase separation might be an evolutionarily conserved strategy evolved by these necrotrophic pathogens to facilitate their infection.
