The apparatus for generating microcurrent of deionized water through a glass capillary tube was prepared. Specimen cell for microscopic observation was devised by combining glass slide with cover glass. When the tip of capillary tube was introduced into the specimen cell containing zoospore suspension, massive aggregation of zoospores at the tip of the tube was obviously observed under the dark ground illumination of Nikon phase contrast microscope. The velocity of water current at the tip of the capillary tube was about 130μ/sec, and nearly equal to the swimming velocity of zoospores. Increasing the velocity of current at the tip of the tube slightly, repulsion zone was formed as in that of electrotaxis and chemotaxis reported previously, and zoospores swam to aggregate around the zone. Repeated mesurments indicated that the velocity of water current at the circumference of repulsion zone was about 130μ/sec. These results suggest that the rate of movement of zoospores is independent of the velocity of the current, and rheotaxis of zoospores is merely a phenamenon of orientation. The minimum velocity of water current as a stimulus for rheotaxis might be presumably too slow to detect by the measurments in this experiment. Rheotaxis of zoospores offers a insight to the process of spread of the pathogenic fungi, i. e. zoospores might be capable of swimming up along the stems of host plants against the water current after rainfall.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_3_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00062275","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00757373","subitem_source_identifier_type":"PISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNames":[{}]}],"creatorNames":[{"creatorName":"桂, 琦一","creatorNameLang":"ja"},{"creatorName":"カツラ, キイチ","creatorNameLang":"ja-Kana"},{"creatorName":"Katsura, Kiichi","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"宮田, 善雄","creatorNameLang":"ja"},{"creatorName":"ミヤタ, ヨシオ","creatorNameLang":"ja-Kana"}]},{"creatorNames":[{"creatorName":"KATSURA, KIICHI","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"MIYATA, YOSHIO","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-20"}],"displaytype":"detail","filename":"KJ00000078786.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"KJ00000078786.pdf","url":"https://kpu.repo.nii.ac.jp/record/4787/files/KJ00000078786.pdf"},"version_id":"641aceab-2fcf-43e8-aad4-333f17081d0e"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper"}]},"item_title":"Phytophthora capsici の遊走子の運動に関する研究 III : 走流性(農学部門)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Phytophthora capsici の遊走子の運動に関する研究 III : 走流性(農学部門)","subitem_title_language":"ja"}]},"item_type_id":"3","owner":"14","path":["410"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-02-20"},"publish_date":"2017-02-20","publish_status":"0","recid":"4787","relation_version_is_last":true,"title":["Phytophthora capsici の遊走子の運動に関する研究 III : 走流性(農学部門)"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2024-04-19T04:27:51.361786+00:00"}
