Microscopic observations of roots of co-cultivated B. monnieri L. with P. indica 3 months, roots were observed under light microscope with magnification of 400 × using with trypan blue stain. Septate hyphae with pear shaped (a) and globular chlamydospores (b) grows on culture media in co-cultivated plants under in vitro, c treated plant root, d control plant root, mature chlamydospores inside the roots (e) and root tip (f) of co-cultivated plants, intercellular hyphal network on root surface (g) as well as inside the root (h) of co-cultivated plants, intracellular arbuscules developed in co-cultivated plants roots. j typical fungal developmental stages were observed in adjacent cells in treated plant root, viz. chlamydospore, emerging hyphae from germinating spore and elongated hyphae
