| description | Strawberry Fusarium wilt, mainly caused by <i>Fusarium oxysoporum</i> f. sp. <i>Fragariae</i> (<i>Fof</i>), seriously threatens the yield and quality of strawberry. <i>Piriformospora indica</i> is an endophytic fungus that can colonise the roots of a wide range of plants, promoting plant growth and enhancing plant resistance. Against this background, the positive effects of <i>P. indica</i> on the growth of the daughter plants of ‘Benihoppe’ strawberry (<i>Fragaria</i> × <i>ananassa</i> Duch.) under <i>Fof</i> stress were investigated in this study. The study began by examining the inhibitory effect of <i>P. indica</i> on <i>Fof</i> growth through dual culture on agar plates. Subsequently, a symbiotic system between <i>P. indica</i> and strawberry plantlets was established, and the impact of <i>P. indica</i> on Fusarium wilt resistance and related physiological and biochemical indexes of the plantlets were evaluated. The results indicate that fungus colonization with <i>P. indica</i> significantly enhances the growth indices of strawberries, including plant height, petiole length, petiole diameter, and leaf area. Additionally, the activities of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) in the leaves of <i>P. indica</i> were increased, and the content of malondialdehyde (MDA) was decreased compared to those without colonization. Under the stress from <i>Fof</i>, the growth indexes of plant height, stem diameter, leaf area, petiole diameter, and root length of strawberry plants colonization with <i>P. indica</i> were significantly higher than those without colonization and the symptoms of wilting were relatively mild. The activities of SOD, POD, and CAT in roots and leaves of plants colonized with <i>P. indica</i> were significantly increased compared to those without colonization. Furthermore, the content of MDA in roots was decreased. These results suggested that <i>P. indica</i> could increase resistance to Fusarium wilt in strawberry by increasing the activity of antioxidant enzymes and reducing the content of MDA. |
