ABSTRACT = {Endophytes associated with plants are recognized as bio-reservoirs of natural products and denote a significant symbiotic interaction in nature. Endophytes penetrate the plant’s interior tissues without showing any indications of disease or obvious alterations. In this study, the potential of a novel and new isolated plant growth-stimulating fungus, <i>Coniothyrium aleuritis</i>, was evaluated against PVY (the pathogen potato virus Y) on potato plants. Many parameters, including disease severity, PVY titer, enzymatic profiling, defense-related biochemical marker (carotenoid), phenolic compounds, proline content, as well as growth and yield parameters, have been investigated to clarify the role of <i>C. aleuritis</i> isolate in mitigating PVY-induced damage due to virus infection. Potato and tobacco plants treated with <i>C. aleuritis</i> grew faster, showed fewer symptoms of disease, and had lower levels of PVY accumulation than plants grown without the treatment. Antioxidant enzymes polyphenol oxidase, catalase, and superoxide dismutase were increased in treated potatoes. A notable upsurge in the transcription levels of defensive genes (<i>PR1b</i>, and <i>PAL1</i> in potato and <i>PR1</i> and <i>Coi1</i> in tobacco), phenolic compounds, carotenoid, and proline contents was observed in treated plants after inoculation. All the experimental and analytical data show that <i>C. aleuritis</i> is effective in supporting potato yield and preventing PVY infection. These findings suggest that <i>C. aleuritis</i> is a promising and eco-friendly treatment for controlling PVY infections.},
