内容記述(抄録等)The elctron-microscopic studies on plant tissues are at present scarcely known、and a similar study on the club-root tissues of crucifers has also not yetbeen done. WORONIN,CooK and SCHWARTZ and some other investigators studied on the life cycle of the causal organism by means of the ordinal microscope,though some features of the life history remain still obscure. This article deals with the electron-microscopic observation on the club-root tissues of Chinese cabbage (Brassica chinensis L.; Nozaki N0. 2 variety)infected with Plasmodeopora brassicae WOR.which were collected in Yamaguti Pref. ,were carried out by means of ultra-thin sectioning・ The material tissues were fixed with 1% osmic acid (M/15 phosphate buffer,pH 6.0)and embeded with methacrylate plastics and sectioned by ultra microtometo be thinner than 0.05μ.The results obtained by the observations on the electron-micrographs are as follows: 1.In the protoplasm of plasmodium of the causal organism, several nuclei,many cytoplasmic granules and some mitochondria were observed. The mitochon-drium is a small rod-shaped sheathed body, averaging about 0.3×1.5μin size and the mitochondrial membrane seems to be doubled. The existence of abundant mitochondria in the plasmodium seems to be significant as it closely co-relates tothe increased metabolic activities in the diseased tissues. 2.Each mononucleate spore divided from plasmodium contains a single nucleus in its center and electron-dense granules in its cytoplasm. 3.Many sharp-pointed prickles were found on the outer membrane of each mononucleate spore.
