This stimulative effect appeared within 20-30min. after the bacteria were in contact with Phytophthora, and the zoosporangia were accomplished following 4-5 hrs. Such bacterial stimulation did not spread over the bacterial colony. The culture filtrate of the bacteria passed through millipore filter did not show the stimulative effect. These results indicate that the stimulatiive substance might be short life metabolic product or products, so contact with living bacteria is necessary for zoosporangium production of Phytophthora. Bacteria transferred from broth cultures show larger stimulative effect than transfered from agar slant media made from the same nutrients. Among 15 Phytophthora cultures over 8 species, 3 species were stimulated by the bacteria but other did not show such a striking responce. These unsusceptible Phytophthora produced no or few zoosporangia even under natural condition, originally. Among 12 species of bacteria tesed, Pseudomonas revealed the most active stimulation. There was no appreciable difference in stimulative activity through growth stage or age of the bacteria in broth culture until 7 days. At weak alkali pH range of culture media both the bacterial growth and the stimulatory effect were increased, more than acidic condition. Phytophthora mycelium grown on oatmeal agar media was more rapidly react with the bacteria than PDA, and the mycelium grown on broth agar media could not produce zoosporangia in spite of the presence of the bacteria. The bacteria destroyed the zoospore of Phytophthora but not zoosporangial membrane. From the results of the test on the physiological characteristics of the bacteria, it is considered that the bacteria is Pseudomonas riboflavina regardless of the fact that the result did not show quite agreement with Bergey's description.","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":[{"creatorNames":[{"creatorName":"正子, 朔","creatorNameLang":"ja"},{"creatorName":"マサゴ, ハジメ","creatorNameLang":"ja-Kana"}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"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":"MASAGO, HAJIME","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"KATSURA, KIICHI","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":"KJ00000078854.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"KJ00000078854.pdf","url":"https://kpu.repo.nii.ac.jp/record/4855/files/KJ00000078854.pdf"},"version_id":"c321cc8b-30c1-400c-b071-477811ac1e3d"}]},"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":"Pseudomonas sp. による Phytophthora capsici LEON. の遊走子のう形成刺戟(農学部門)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Pseudomonas sp. による Phytophthora capsici LEON. の遊走子のう形成刺戟(農学部門)","subitem_title_language":"ja"},{"subitem_title":"Stimulation of Pseudomonas sp. on the zoosporangia formation of Phytophthora capsici LEON (Agriculture)","subitem_title_language":"en"}]},"item_type_id":"3","owner":"14","path":["414"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-02-20"},"publish_date":"2017-02-20","publish_status":"0","recid":"4855","relation_version_is_last":true,"title":["Pseudomonas sp. による Phytophthora capsici LEON. の遊走子のう形成刺戟(農学部門)"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2024-03-11T04:47:56.623799+00:00"}
