Biocontrol potential of endophytic Trichoderma harzianum AUMC 14897 against Fusarium seedling blight disease in oat.

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
backgroundOat (Avena sativa L.) represents one of the important cereal crops grown in different areas around the world due to its use in human nutrition, food industry, biomaterials, and pharmaceutical industries. Fusarium seedling blight disease (FSBD) represents one of the most dangerous diseases affecting oat cultivation. Endophytic fungi proved to be useful in plant disease management. Therefore, the present study investigated the impact of applied endophytic Trichoderma harzianum AUMC 14897 culture filtrate (CF) on disease severity, plant performance, defense systems, antioxidant activity, and stress-related genes expression in oat plants infected with Fusarium oxysporum.
resultsThe dual culture assay results revealed that T. harzianum is antagonistic against F. oxysporum and could inhibit the growth by 86.6% seven days post inoculation. Scanning electron microscope results showed that the antagonism mechanisms include nutrition, space competition, and mycoparasitism. GC-MS analysis demonstrated the presence of several volatile organic compounds in T. harzianum CF and each component might contribute to its biological activity. In a greenhouse experiment, spraying and irrigation with T. harzianum CF revealed less severe symptoms and slower disease development in the infected oat plants compared to untreated plants. Moreover, T. harzianum CF treatment significantly enhanced the levels of total reducing power, phenolics, flavonoids, chlorophyll, carotenoids, antioxidant enzymes, and stress-related genes expression in F. oxysporum-infected oat plants.
conclusionsOur results demonstrated T. harzianum CF has an effective role in controlling FSBD in oat plants as a novel biocontrol agent.
