The close relationship between swimming activity of the zoospore and formation of the miniature zoosporangium was described in this paper. Zoospores of Phytophthora capsici Leon. No. 65 continue to swim for about 9 hours at 20℃ (Fig. 3). Zoospores incubated at 20℃ were transfered with 2 hour interval to 32℃, the optimum temperature for sporangium formation. Zoospores incubated at this temperature encysted within 45 minutes, germinated and formed zoosporangia within 18 hours. The result is shown in Fig. 4. Zoospores encysted immediatelly, 2,4,6 and 8 hours after spouting formed the miniature zoosporangia at the rate of 72.1,30.2,21.9,16.7 and 8.2% respectively. The formation of miniature zoosporangia from cystospores could therefore be negatively correlated to the swimming time of zoospores. An another experiment shows that formation of miniature zoosporangia is suppressed by a high temperature treatment at 36℃ for 15min., but germination of cystospores is hardly influenced by this treatment. Swimming zoospores in 20℃ water were taken out with 2 hour intervals in the same manner as in the previous experiment, incubated at 36℃ for 15min., and then transfered to the optimum temperature for spore germination, 28℃. The results (Fig. 5) shows that the maximum lengths of germ tubes of cystospores after 6 hour incubation were nearly equal irrespective of the differences in swimming time of zoospores. These results could be accounted for by the following assumptions. (1) The source of energy for swimming of zoospores is different from that for germination of cystospores. (2) Energy source remained from the swimming is involved in the shift of metabolic systems from pathway for the tube elongation to that for miniature zoosporangium formation. A preliminary experiment suggests that the energy source could be phospholipids.","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":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"宮田, 善雄","creatorNameLang":"ja"},{"creatorName":"ミヤタ, ヨシオ","creatorNameLang":"ja-Kana"},{"creatorName":"Miyata, Yoshio","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]},{"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":[{}]},{"creatorAffiliations":[{"affiliationNames":[{}]}],"creatorNames":[{"creatorName":"卜部, 貞男","creatorNameLang":"ja"},{"creatorName":"ウラベ, サダオ","creatorNameLang":"ja-Kana"},{"creatorName":"Urabe, Sadao","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]}]},"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":"KJ00000078826.pdf","filesize":[{"value":"754.4 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"KJ00000078826.pdf","url":"https://kpu.repo.nii.ac.jp/record/4827/files/KJ00000078826.pdf"},"version_id":"54fa89df-d128-4454-9bcc-ccc6371dc8c1"}]},"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 LEON. の遊走子の運動に関する研究 VI : 遊走子の遊泳と小遊走子のう形成(農学部門)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Phytophthora capsici LEON. の遊走子の運動に関する研究 VI : 遊走子の遊泳と小遊走子のう形成(農学部門)","subitem_title_language":"ja"}]},"item_type_id":"3","owner":"4","path":["412"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-02-20"},"publish_date":"2017-02-20","publish_status":"0","recid":"4827","relation_version_is_last":true,"title":["Phytophthora capsici LEON. の遊走子の運動に関する研究 VI : 遊走子の遊泳と小遊走子のう形成(農学部門)"],"weko_creator_id":"4","weko_shared_id":-1},"updated":"2024-04-25T04:31:37.570077+00:00"}
