[Electron microscopy study of the microorganism topography on plant roots]

The topography of microorganisms in the root cap zone and in the absorption zone was studied with 7-day-old wheat seedlings. No microorganisms were detected in the root cap zone. Individual microorganisms as well as their accumulations were registered in the absorption zone. The topography of microorganisms in this zone was characterized. Different morphological forms were present among microorganisms. Types of interaction between these microorganisms and the cells of root epidermis are discussed.
