Fig. 4From: Suppression of Magnaporthe oryzae and interaction between Bacillus subtilis and rice plants in the control of rice blastTransmission electron micrographs of M. oryzae cells exposed to liquid culture of B. subtilis. M. oryzae P131 conidia and hyphae in the a–c absence of either agent, d, e presence of liquid culture of B. subtilis SYX04 and f, g liquid culture of B. subtilis SYX20 at a concentration of 1 × 108 CFU/g. Fungal cells treated with SYX04 and SYX20 exhibited significant morphological and ultrastructural abnormalities, such as increased vacuolation, invagination distortion, retraction of the plasma membranes, and formation of polymorphic vesicles. f, g Loss of plasma membrane integrity and the formation of pores were observed.
