Comparative transcriptome analysis reveals significant differences in gene expression between pathogens of apple Glomerella leaf spot and apple bitter rot.

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
backgroundApple Glomerella leaf spot (GLS) and apple bitter rot (ABR) are two devastating foliar and fruit diseases on apples. The different symptoms of GLS and ABR could be related to different transcriptome patterns. Thus, the objectives of this study were to compare the transcriptome profiles of Colletotrichum gloeosporioides species complex isolates GC20190701, FL180903, and FL180906, the pathogen of GLS and ABR, and to evaluate the involvement of the genes on pathogenicity.
resultsA relatively large difference was discovered between the GLS-isolate GC20190701 and ABR-isolates FL180903, FL180906, and quite many differential expression genes associated with pathogenicity were revealed. The DEGs between the GLS- and ABR-isolate were significantly enriched in GO terms of secondary metabolites, however, the categories of degradation of various cell wall components did not. Many genes associated with secondary metabolism were revealed. A total of 17 Cytochrome P450s (CYP), 11 of which were up-regulated while six were down-regulated, and five up-regulated methyltransferase genes were discovered. The genes associated with the secretion of extracellular enzymes and melanin accumulation were up-regulated. Four genes associated with the degradation of the host cell wall, three genes involved in the degradation of cellulose, and one gene involved in the degradation of xylan were revealed and all up-regulated. In addition, genes involved in melanin syntheses, such as tyrosinase and glucosyltransferase, were highly up-regulated.
conclusionsThe penetration ability, pathogenicity of GLS-isolate was greater than that of ABR-isolate, which might indicate that GLS-isolate originated from ABR-isolates by mutation. These results contributed to highlighting the importance to investigate such DEGs between GLS- and ABR-isolate in depth.
