The kineto-microtubules are attached to the halo (convex surface) and the mesh of thin threads of chromonema was attached to the inner concave surface of the core. 4 ) The other edge of the bundle of kineto-microtubules stops somewhere near the inner nuclear membrane, inside of the polar area. 5) In the third prezygotic division, the elongated nucleus runs parallel to the cell-to-cell joint region. The pronucleus positioned in the apex of the joint region becomes a migratory pronucleus and the latter part becomes a stationary pronucleus. 6) Within the cytoplasm of the outer side of the migratory pronucleus, there are numerous microtubules and microfilaments which contribute to the processes of pronucleus exchange and the cell-to-cell joint region reformation after such exchange.\nKey Words : ultrastructure, conjugation, pronucleus, kinetochore.","subitem_description_type":"Abstract"}]},"item_10002_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"奈良佐保女学院短期大学"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"01925043","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"菅沼, 美子"},{"creatorName":"スガヌマ, ヨシコ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"535","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"為房, 智子"},{"creatorName":"タメフサ, ノリコ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"542","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"SUGANUMA, Yoshiko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"537","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"TAMEFUSA, Noriko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"543","nameIdentifierScheme":"WEKO"}]}]},"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","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"接合期Tetrahymena thermophilaの原核形成過程の電顕的研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"接合期Tetrahymena thermophilaの原核形成過程の電顕的研究"},{"subitem_title":"Electron Microscopy of the Formation Process of Gametic Pronuclei during Conjugation in Tetrahymena thermophila","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["24"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-11-04"},"publish_date":"2016-11-04","publish_status":"0","recid":"152","relation_version_is_last":true,"title":["接合期Tetrahymena thermophilaの原核形成過程の電顕的研究"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2023-05-15T08:50:05.654066+00:00"}
