From the observations it is confirmed that G. mosseae was able to colonise the cortical cell of tomato root.

Large number of small vacuoles was observed as a response to the heavy colonisation by G. mosseae. The entire arbuscular was surrounded by the plasmalemma of the cell host. The infection of AMF occurs through the hyphae structure between root epidermal cells and the huge number of nuclei. The Nucleus was observed in colonized cells and new entry point in the cell wall.

Abstract

Tomato roots were able to colonise intensively by Glomus mosseae. Scanning electron microscopy SEM and transmission electron microscopy TEM observations showed the root cell wall was colonised. The aim of the study was to detect the structures of G. mosseae in tomato cells using SEM and TEM. From the observations it is confirmed that G. mosseae was able to colonise the cortical cell of tomato root. The presence of mycorrhizal fungi structures in abundance that causes lignifications for the cell wall. Mature spores of G. mosseae in addition to net of vesicles and arbuscules were seen attached to the root cells. Large number of small vacuoles was observed as a response to the heavy colonisation by G. mosseae. The entire arbuscular was surrounded by the plasmalemma of the cell host. The infection of AMF occurs through the hyphae structure between root epidermal cells and the huge number of nuclei. The Nucleus was observed in colonized cells and new entry point in the cell wall. AMF penetrates roots and grow extensively between and within living cortical cells and affects many aspects of root metabolism.
