Abstract In greenhouse experiments, we investigated the potentials of Piriformospora indica (Pi) to penetrate and colonise roots of wheat and to induce beneficial effects on growth as well as to reduce seedlings damping-off disease of wheat caused by the soil-borne fungus Fusarium oxysporum (Fo). By microscopy we observed the intracellular hyphae within root cortex cells of 7–14 day-old plants and chlamydospores within root cortex cells of 14–28 day-old plants and within root hair cells of 21–28 day-old plants. Moreover, diagnostic PCR based on the β-tubulin gene marker confirmed the presence of Pi in roots of inoculated plants. Also, we found that plants inoculated with Pi exhibited a better growth of roots and shoots as well as early flowering as compared with non-treated plants. Moreover, Pi conferred tolerance of wheat to seedlings damping-off i.e. by reducing the harmful effects of Fo on infected plants.
