Cleavage of the Babuvirus Movement Protein B4 into Functional Peptides Capable of Host Factor Conjugation is Required for Virulence.

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
Banana bunchy top virus (BBTV) poses a serious danger to banana crops worldwide. BBTV-encoded protein B4 is a determinant of pathogenicity. However, the relevant molecular mechanisms underlying its effects remain unknown. In this study, we found that a functional peptide could be liberated from protein B4, likely via proteolytic processing. Site-directed mutagenesis indicated that the functional processing of protein B4 is required for its pathogenic effects, including dwarfism and sterility, in plants. The released protein fragment targets host proteins, such as the large subunit of RuBisCO (RbcL) and elongation factor 2 (EF2), involved in protein synthesis. Therefore, the peptide released from B4 (also a precursor) may act as a non-canonical modifier to influence host-pathogen interactions involving BBTV and plants.
