However, the mechanism to perceive the gravity and to transmit this signal in roots is not clear. According to the hypothesis that root columella cells percept the gravity, genes were searched that are ectopically induced in root columella cells from Arabidopsis T-DNA enhancer trap lines. As a result, 7 lines were obtained that induced GFP in root columella cells. Using three sets of nest primers designed from the T-DNA (Gal4-GFP) sequence, 45 highly specific amplifications were obtained after Tail-PCR. Sequence determination showed that 2 lines had the T-DNA region inserted near the genes for a Myb family transcription factor and an auxin responsive protein, respectively. The knockout lines are now being searched and the promoter regions for these genes being identified., 資料番号: AA0046917037}, pages = {114--116}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)}, title = {エンハンサートラップラインを用いた重力感受細胞特異的発現遺伝子の単離}, year = {2004} }
