Loss of Pathogenicity and Evidence of Horizontal Gene Transfer in Colletotrichum gloeosporioides From a Medicinal Plant.

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
Colletotrichum gloeosporioides is a major agricultural pathogen of crops that has also been identified as an endophyte of the medicinal plant Huperzia serrata. Both H. serrata and C. gloeosporioides produce huperzine A, a potential treatment for Alzheimer's disease. In this study, a nonpathogenic C. gloeosporioides strain (NWUHS001) was isolated and its genome sequenced. Gene structure prediction identified 15,413 protein-coding genes and 879 noncoding RNAs. Through PHI-base database prediction, we found that NWUHS001 lacks two key pathogenicity genes CgDN3 and cap20, which may be the cause of its nonpathogenicity. Comparative genomic analysis showed that the number of genes encoding pectin lyase B (pelB), pectin lyase (pnl) and polygalacturonase (pg) in NWUHS001 was significantly lower than that in pathogenic strains during the expansion of mycelium into host tissues. This caused slow growth and incapability to penetrate host cells. In contrast, in NWUHS001, genes involved in carbon acquisition such as ribose and amino sugar metabolic pathways were enriched, indicating active metabolite exchange with the host. In addition, by comparing the genome of NWUHS001 with that of the host H. serrata, we found that polyketosynthetase (pksIII), a key gene in the host huperzine A biosynthetic pathway, may possibly have been acquired from the fungus by horizontal gene transfer (HGT). This study explained the possible genetic evolution mechanism of C. gloeosporioides from pathogenicity to nonpathogenicity, which is of value for studying the interaction between microorganisms and plants. It also provided clues to the genetic evolution of the biosynthetic pathway of huperzine A.
