Discovery of a susceptibility factor for Fusarium head blight on chromosome 7A of wheat.

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 messageDiscovery and mapping of a susceptibility factor located on the short arm of wheat chromosome 7A whose deletion makes plants resistant to Fusarium head blight. Fusarium head blight (FHB) disease of wheat caused by Fusarium spp. deteriorates both quantity and quality of the crop. Manipulation of susceptibility factors, the plant genes facilitating disease development, offers a novel and alternative strategy for enhancing FHB resistance in plants. In this study, a major effect susceptibility gene for FHB was identified on the short arm of chromosome 7A (7AS). Nullisomic-tetrasomic lines for homoeologous group-7 of wheat revealed dosage effect of the gene, with tetrasomic 7A being more susceptible than control Chinese Spring wheat, qualifying it as a genuine susceptibility factor. Five chromosome 7A inter-varietal substitution lines and a tetraploid Triticum dicoccoides 7A substitution line showed similar susceptibility as that of Chinese Spring, indicating toward the commonality of the susceptibility factor among these diverse genotypes. The susceptibility factor was named as Sf-Fhb-7AS and mapped on chromosome 7AS to a 48.5-50.5 Mb peri-centromeric region between del7AS-3 and del7AS-8. Our results showed that deletion of Sf-Fhb-7AS imparts 50-60% type 2 FHB resistance and its manipulation can be used to enhance resistance against FHB in wheat.
