The number is butterflies and bees, making their eyes spectrally richer. Is this an adaptation for having better color vision in flower-visitors? We addressed this question by comparing the eye development in flies and butterflies. A transcription factor Prospero (Pros) is expressed in a short-wavelength receptor, R7, in all commatidia in flies. We found Pros is expressed in two cells per an ommatidium in butterflies　: R7 seems to be duplicated. Ommatidial heterogeneity is detected in flies by stochastic expression of Spineless (Ss) in R7. In butterflies, two R7-like cells express Ss in three patterns, on/off, on/on and off/off, as if they correspond to three ommatidial types. In fact, butterflies whose ss gene is knockes-out have the UV-UV type commatidia. It thus appears that the spectral richness of butterfly eyes is associated with duplication of R7-like cell in the process of adaptation.\n","subitem_description_type":"Abstract"}]},"item_2_description_18":{"attribute_name":"科研費研究者番号","attribute_value_mlt":[{"subitem_description":"20167232 | https://nrid.nii.ac.jp/ja/nrid/1000020167232/","subitem_description_type":"Other"}]},"item_2_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"科学研究費補助金研究成果報告書 \n研究代表者:蟻川謙太郎[総合研究大学院大学先導科学研究科教授] ","subitem_description_type":"Other"}]},"item_2_relation_11":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"KAKEN（科学研究費補助金データーベース）"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?kw=%E8%A4%87%E7%9C%BC%E9%80%B2%E5%8C%96%E7%A0%94%E7%A9%B6%E3%81%AE%E6%96%B0%E6%A9%9F%E8%BB%B8","subitem_relation_type_select":"URI"}}]},"item_2_text_19":{"attribute_name":"研究分野","attribute_value_mlt":[{"subitem_text_value":"動物生理・行動"}]},"item_2_text_20":{"attribute_name":"研究種目","attribute_value_mlt":[{"subitem_text_value":"挑戦的萌芽研究 "}]},"item_2_text_5":{"attribute_name":"報告年度","attribute_value_mlt":[{"subitem_text_value":"2016"}]},"item_2_version_type_12":{"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"蟻川, 謙太郎"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-05-28"}],"displaytype":"simple","filename":"26650117seika_arikawa.pdf","filesize":[{"value":"284.4 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"研究成果報告書","url":"https://ir.soken.ac.jp/record/5741/files/26650117seika_arikawa.pdf"},"version_id":"3b5de5d2-ee72-4a81-bed0-15dd9f606ff3"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"複眼","subitem_subject_scheme":"Other"},{"subitem_subject":"視細胞","subitem_subject_scheme":"Other"},{"subitem_subject":"進化","subitem_subject_scheme":"Other"},{"subitem_subject":"発生","subitem_subject_scheme":"Other"},{"subitem_subject":"ショウジョウバエ","subitem_subject_scheme":"Other"},{"subitem_subject":"チョウ類","subitem_subject_scheme":"Other"},{"subitem_subject":"調節因子","subitem_subject_scheme":"Other"},{"subitem_subject":"国際研究者交流","subitem_subject_scheme":"Other"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"複眼進化研究の新機軸：視細胞のdeep homology","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"複眼進化研究の新機軸：視細胞のdeep homology"},{"subitem_title":"New direction of evolutionary study of compound eyes: deep homology of photoreceptors","subitem_title_language":"en"}]},"item_type_id":"2","owner":"24","path":["34"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-05-28"},"publish_date":"2018-05-28","publish_status":"0","recid":"5741","relation_version_is_last":true,"title":["複眼進化研究の新機軸：視細胞のdeep homology"],"weko_creator_id":"24","weko_shared_id":-1},"updated":"2023-06-20T14:35:46.000589+00:00"}
