PROBLEM TO BE SOLVED: To provide a plant factory for molecular diagnosis where the growth condition of a plant body is determined based on information other than that on appearance of the plant body so as to enable selection of the plant body and/or highly-accurate environmental control.SOLUTION: The plant factory for molecular diagnosis includes a molecular diagnostic system diagnosing the growth condition of the plant body and modified so as to recognize internal-gene representation increased in accordance with the growth of the plant with bioluminescence. The molecular diagnostic system includes: light projection means for projecting cultivation light for growing a photogenesis gene-introduced plant body into which the photogenesis gene is introduced photogenesis image-acquisition means for taking an image of the internal-gene representation increased in accordance with the growth of the photogenesis gene-introduced plant body, as the bioluminescence, so as to acquire the photogenesis image and growth condition-diagnosing means for diagnosing the growth condition of the photogenesis gene-introduced plant body based on the light emission amount of the bioluminescence in the photogenesis image.COPYRIGHT: (C)2012,JPO&INPIT【課題】植物体の外観情報以外の情報に基づき植物体の生育状態を判定し、植物体の選別や環境制御を高精度に行うことを可能とする技術を提供する。【解決手段】植物の生育に伴い増加する内在性遺伝子の発現量を生物発光で識別することができるように改変された植物体の生育状態を診断する分子診断システムを備えた分子診断型植物工場であって、該分子診断システムが、発光遺伝子を導入した発光遺伝子導入植物体を生育するための栽培光を投射する光投射手段と、該発光遺伝子導入植物体の生育に伴い増加した内在性遺伝子の発現量を生物発光として撮像して発光画像を取得する発光画像取得手段と、該発光画像における生物発光の発光量に基づいて該発光遺伝子導入植物体の生育状態を診断する生育状態診断手段と、を備えた、分子診断型植物工場により解決する。【選択図】図1
