Description

Ultra-thin sections of the hypertrophied stem-tissues of Brassica cernua infected by Albugo macrospora were studied under an electron-microscope. Hypertrophied cell had a large vacuole and a thin peripheral layer of cytoplasmic area. Sometimes plasmolysis was observed but the disintegration of double membrane was not seen in nuclei, chloroplasts and mitochondria. Fungal hyphae were recognized in inter-cellular spaces and inside of the cell of suscept tissue.
Although the tips of hyphae were recognized in the suscept cell, the hyphae(hausto rium) were always surrounded by an invaginated cytoplasm. In the haustorial cells, large mitochondria, endoplasmic leticula and vacuole were found.
