Novel Anthraquinone Chlorination Contributes to Pigmentation and ATP Formation in Thermomyces dupontii.

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
Fungal pigments, particularly anthraquinones, play critical roles in food industrial applications due to their vivid hues and bioactive properties. Despite their significance, the functional mechanisms underlying pigment variation and their natural functions remain poorly understood. Here, we investigate the genetic and biochemical basis of anthraquinone-mediated pigmentation in the thermophilic fungus Thermomyces dupontii. Through a combination of transcriptomic, biochemical and chemical analyses, we identified the flavin-dependent halogenase gene (hal) as a key controller of anthraquinone chlorination, a process essential for fungal pigmentation and metabolic responses to low temperature stress. Disruption of hal abolished chlorinated anthraquinone production, reduced colony pigmentation and impaired ATP production. We characterised novel chlorinated and dichlorinated anthraquinones, highlighting chlorination's role in enhancing the structural diversity of anthraquinones and fungal pigmentation. Detailed bioassays indicated that hal-mediated anthraquinone chlorination contributes to fungal survival under cold stress by enhancing two distinct energy modes. This study provides new insights into the ecological significance of fungal pigmentation and opens avenues for the biotechnological exploitation of fungal pigments in food industrial and medical research.
