Enhanced resistance to fungal and bacterial diseases in tomato and Arabidopsis expressing BSR2 from rice.
Article in Plant cell reports, 2020. 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
key messageThe overexpression of rice BSR2 would offer a simple and effective strategy to protect plants from multiple devastating diseases in tomato and Arabidopsis. Many devastating plant diseases are caused by pathogens possessing a wide host range. Fungal Botrytis cinerea and Rhizoctonia solani, as well as bacterial Pseudomonas syringae and Ralstonia pseudosolanacearum are four such pathogens that infect hundreds of plant species, including agronomically important crops, and cause serious diseases, leading to severe economic losses. However, reports of genes that can confer resistance to broad host-range pathogens via traditional breeding methods are currently limited. We previously reported that Arabidopsis plants overexpressing rice BROAD-SPECTRUM RESISTANCE2 (BSR2/CYP78A15) showed tolerance not only to bacterial P. syringae pv. tomato DC3000 but also to fungal Colletotrichum higginsianum and R. solani. Rice plants overexpressing BSR2 displayed tolerance to two R. solani anastomosis groups. In the present study, first, BSR2-overexpressing (OX) Arabidopsis plants were shown to be additionally tolerant to B. cinerea, R. solani, and R. pseudosolanacearum. Next, tomato 'Micro-Tom' was used as a model to determine whether such tolerance by BSR2 can be introduced into dicot crops to prevent infection from pathogens possessing wide host range. BSR2-OX tomato displayed broad-spectrum disease tolerance to fungal B. cinerea and R. solani, as well as to bacterial P. syringae and R. pseudosolanacearum. Additionally, undesirable traits such as morphological changes were not detected. Thus, BSR2 overexpression can offer a simple and effective strategy to protect crops from multiple destructive diseases.
