COMPASS subunit Bre2 regulates chromatin remodeler Arp9 to control Aspergillus flavus aflatoxin synthesis and virulence.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Aspergillus flavus, along with its notorious secondary metabolite aflatoxin B1 (AFB1), seriously endangers human health. Histone methyltransferase complex COMPASS (complex of proteins associated with Set1) plays a crucial role in regulating aflatoxin biosynthesis and virulence of A. flavus, but the underlying mechanism is unclear. Here, we find that Bre2, the key subunit of COMPASS, regulates AFB1 biosynthesis, fungal morphogenesis, and virulence through modulation of H3K4 methylation. ChIP-seq and biochemical analyses reveal that chromatin remodeling factor (CRF) Arp9 is directly targeted by Bre2, and Arp9 exerts bio-functions through interacting with the other CRFs such as RSC8, Arp7, and Sth1. ATAC-seq results indicate that Arp9 contributes to fungal pathogenicity by modulating chromatin conformation of genes that are involved in secondary metabolism, morphogenesis, and virulence. The study reveals an epigenetic signaling pathway mediated by chromatin remodeler Arp9 and provides a potential strategy for the control of pathogenic fungi and mycotoxins.
