The durable resistance gene Tm-22 remains partially resistant to tomato brown rugose fruit virus.
Article in PLoS pathogens, 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
The tomato Tm-22 gene is a highly effective, and durable resistance gene in agriculture that has protected tomato production against viruses of the Tobamovirus genus, such as tomato mosaic virus (ToMV) and tobacco mosaic virus (TMV) for over 60 years. This dominant R gene, originally sourced from wild tomato species (Solanum peruvianum), acts by recognizing the viral movement protein (MP) and triggering an immune response, often resulting in extreme resistance (ER). However, this durable protection is challenged by a recently emerged new tobamovirus named tomato brown rugose fruit virus (ToBRFV, Tobamovirus fructirugosum). ToBRFV-encoded MP is responsible for ER breakdown. Here, we present evidence that while ToBRFV can evade Tm-22-mediated ER, Nicotiana benthamiana and tomato plants carrying Tm-22 still remain partially resistant to ToBRFV. We show that ToBRFV MP is recognized by and interacts with Tm-22 to trigger an attenuated hypersensitive response. Moreover, we discover that overexpression of Tm-22 can enhance resistance to ToBRFV. These findings demonstrate the practical value of Tm-22 in ongoing resistance breeding programs and open a potential avenue to restore Tm-22 immunity through upregulation of Tm-22 expression.
