These fish naturally occur in normal bisexual diploid form as well as their triploid gynogenetic counterparts. Notably, the latter form reproduce themselves by parthenogenetic, or clonal, development of unreduced and unfertilized eggs, thus giving rise to genetically identical all-female offspring. The primary objective of this study was to identify and analyze genes that play crucial roles in the complicated cascade or network for induction of meiotic division to produce the gametes in almost all multicellular organisms at the final step of formation of their germ cells. In gynogenetic fish that skip meiosis and lay triploid eggs whose genomes are identical to that of somatic cells, a certain set of genes must be different from that of bisexual kin. This difference was studied by comparing genes and their expression in the ovaries of both diploid and triploid fishes. Namely, ovarian RNAs were extracted and compared between the two forms for their nucleotide sequences and subtype variation. Differential-display analyses for RT-PCR products resulting from twenty different primer sets singled out a convincing candidate gene fragment referred to as KD16 that could be linked to mechanism for regulation of germ cell differentiation. This gene was shown to have five or more alleles, each of which was expressed differently between diploid and triploid fishes and appeared to be ovary-specific. The entire stretch (approx. 1.7 kb) of cDNA of KD16 gene obtained by 5' RACE method was analyzed for its nucleotide sequence and searched for homology with data-bank sequences. The results indicate that each of five subtypes encodes the \"TRIM proteins\", i.e., proteins with the RING domain and the B-box domain. This implies a possible role of this gene in reproductive regulation.","subitem_description_type":"Other"}]},"item_12_description_2":{"attribute_name":"ページ属性","attribute_value_mlt":[{"subitem_description":"P(論文)","subitem_description_type":"Other"}]},"item_12_description_3":{"attribute_name":"記事種別","attribute_value_mlt":[{"subitem_description":"特集","subitem_description_type":"Other"}]},"item_12_description_34":{"attribute_name":"format","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_12_description_4":{"attribute_name":"Type","attribute_value_mlt":[{"subitem_description":"FEATURE ARTICLES","subitem_description_type":"Other"}]},"item_12_publisher_19":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"麻布大学"}]},"item_12_publisher_20":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"Azabu University"}]},"item_12_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1346-5880","subitem_source_identifier_type":"ISSN"}]},"item_12_source_id_23":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11561468","subitem_source_identifier_type":"NCID"}]},"item_12_text_10":{"attribute_name":"Author ID","attribute_value_mlt":[{"subitem_text_value":"-"},{"subitem_text_value":"-"},{"subitem_text_value":"000030"}]},"item_12_text_11":{"attribute_name":"所属機関","attribute_value_mlt":[{"subitem_text_value":"麻布大学大学院獣医学研究科"},{"subitem_text_value":"麻布大学大学院獣医学研究科"},{"subitem_text_value":"麻布大学大学院獣医学研究科"}]},"item_12_text_12":{"attribute_name":"Institution or Company","attribute_value_mlt":[{"subitem_text_value":"Graduate School of Veterinary Sciences, Azabu University"},{"subitem_text_value":"Graduate School of Veterinary Sciences, Azabu University"},{"subitem_text_value":"Graduate School of Veterinary Sciences, Azabu University"}]},"item_12_text_9":{"attribute_name":"著者ID","attribute_value_mlt":[{"subitem_text_value":"-"},{"subitem_text_value":"-"},{"subitem_text_value":"000030"}]},"item_12_version_type_29":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_12_version_type_30":{"attribute_name":"text version","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"藤谷, 英男"},{"creatorName":"フジタニ, ヒデオ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"藤瀬, 浩"},{"creatorName":"フジセ, ヒロシ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"若尾, 義人"},{"creatorName":"ワカオ, ヨシト","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fujitani, Hideo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fujise, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Wakao, Yoshito","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2004-01-01"}],"displaytype":"detail","filename":"bull_jau_vol9-10-133.pdf","filesize":[{"value":"211.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"bull_jau_vol9-10-133.pdf","url":"https://az.repo.nii.ac.jp/record/4664/files/bull_jau_vol9-10-133.pdf"},"version_id":"052ffdc1-8b61-40da-b9ac-431b42932234"}]},"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":"動物の生殖系列分化の高次調節に関与する遺伝子の解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"動物の生殖系列分化の高次調節に関与する遺伝子の解析"},{"subitem_title":"Search for genes that may be involved in higher order regulation of germ-cell differentiation in animals","subitem_title_language":"en"}]},"item_type_id":"12","owner":"4","path":["455","490"],"pubdate":{"attribute_name":"公開日","attribute_value":"2004-01-01"},"publish_date":"2004-01-01","publish_status":"0","recid":"4664","relation_version_is_last":true,"title":["動物の生殖系列分化の高次調節に関与する遺伝子の解析"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-06-19T07:47:44.046656+00:00"}
