Identification of genes involved in fungal responses to strigolactones using mutants from fungal pathogens.
Article in Current genetics, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
Strigolactones (SLs) as components of root exudates induce hyphal branching of arbuscular mycorrhizal (AM) fungi which is thought to favor the establishment of the beneficial symbiosis. Little is known on how AM fungi respond to SLs. Since AM fungi are poor model systems due to their obligate biotrophism and the lack of genetic transformation protocols, we took advantage of the sensitivity of several phytopathogenic fungi to GR24, a synthetic SLs analog. With the aim to identify the molecular determinants involved in SLs response in AM fungi and assuming conserved mechanisms in the fungal kingdom, we exploited the fungal pathogens Botrytis cinerea and Cryphonectria parasitica, for which mutant collections are available. Exposure of B. cinerea and C. parasitica to GR24 embedded in solid medium led to reduction of fungal radial growth. We set up the screening of a set of well-characterized gene deletion mutants to isolate genotypes with altered responses to SLs. Two B. cinerea mutants (defective of BcTrr1, a thioredoxin reductase and BcLTF1, a GATA transcription factor) turned out to be less responsive to GR24. One feature shared by the two mutants is the overproduction of reactive oxygen species (ROS). Indeed, an oxidizing effect was observed in a B. cinerea strain expressing a redox-sensitive GFP2 in the mitochondrial intermembrane space upon exposure to GR24. ROS and mitochondria are, therefore, emerging as mediators of SLs actions.
