D-Xylose as a repressor or inducer of xylanase expression in Hypocrea jecorina (Trichoderma reesei).

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
For Hypocrea jecorina (anamorph Trichoderma reesei), a filamentous fungus used for hydrolase production in different industries, it has been a long-term practice to use d-xylose as an inducing substance. We demonstrate in this study that the degree of xylanase-encoding gene induction strictly depends on the concentration of d-xylose, which was found to be optimal from 0.5 to 1 mM for 3 h of cultivation. At higher concentrations of d-xylose, a reduced level of xylanase gene expression was observed. In the present study, we also provide evidence that the d-xylose concentration-dependent induction is antagonized by carbon catabolite repressor 1. This repressor mediates its influence on d-xylose indirectly, by reducing the expression of xylanase regulator 1, the main activator of most hydrolase-encoding genes. Additionally, a direct influence of the repressor on xylanase 1 expression in the presence of d-xylose was found. Furthermore, we show that d-xylose reductase 1 is needed to metabolize d-xylose to achieve full induction of xylanase expression. Finally, a strain which expresses xylanase regulator 1 at a constant level was used to partially overcome the negative influence exerted by carbon catabolite repressor 1 on d-xylose.
