Evolution of sympatric host-specialized lineages of the fungal plant pathogen Zymoseptoria passerinii in natural ecosystems.

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 barley disease Septoria Speckled Leaf Blotch, caused by the fungus Zymoseptoria passerinii, last appeared in North America in the early 2000s. Although rare in crops, field sampling of wild grasses in the Middle East revealed the disease persistence in wild barley. Identification of Z. passerinii in various wild barley species prompted us to examine genomic signatures of host specialization and trace the emergence of the domesticated-barley-infecting lineage. Furthermore, we applied virulence assays and confocal laser microscopy to evaluate whether the disease development differs between wild and domesticated barley. Wild- and domesticated-host-infecting populations have diverged, and phylogenetic relationships support the evolution of sympatric host-specialized lineages in wild hosts. Cross-virulence assays showed that Z. passerinii from domesticated hosts infect domesticated barley and its wild ancestor, Hordeum spontaneum. However, wild isolates from Iran did not infect domesticated barley. Wild and domesticated pathosystems have similar disease timing and progression, suggesting its persistence does not depend on a shorter period of incubation. The study supports that a wide range of hosts can foster the evolution of host-specialized lineages in sympatry and provide novel insights into the evolution of understudied fungal pathogens on wild hosts.
