Transcription factor VlPAT2 enhances the resistance of grapevine to Botrytis cinerea by promoting ROS accumulation.
Article in Plant cell reports, 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
key messageThe overexpression of VlPAT2 enhances the resistance of grapevine and Arabidopsis thaliana to Botrytis cinerea, and promotes the accumulation of reactive oxygen species, as well as the expression of multiple PR genes and R genes. Grape grey mould caused by the necrotrophic fungus Botrytis cinerea causes severe economic losses to the grape industry. Identifying disease resistance genes and elucidating their mechanisms provide critical insights for molecular breeding. Here, we report a GRAS family transcription factor VlPAT2 from the grapevine cultivar 'Beta' (Vitis labrusca) that exhibits high resistance to B. cinerea, which is involved in positively regulating grape resistance to this fungal pathogen. The VlPAT2 expression is responsive to treatments of salicylic acid, ethephon, bacterial flagellin peptide flg22, and hydrogen peroxide (H₂O₂). Overexpression of VlPAT2 in grapes and Arabidopsis thaliana can enhance resistance to B. cinerea, accompanied by the accumulation of reactive oxygen species (ROS). In addition, the transcriptional levels of salicylic acid signalling-associated defence genes (PR1 and PR5) and multiple resistance genes (R genes) were significantly upregulated in VlPAT2-overexpressing grape leaves. In conclusion, our findings indicate that the transcription factor VlPAT2 enhances disease resistance in grapevines and provides a gene source for the molecular breeding of grape varieties resistant to B. cinerea.
