第26回宇宙利用シンポジウム(2010年1月25日-26日, 宇宙航空研究開発機構宇宙科学研究本部相模原キャンパス), The Twenty-sixth Space Utilization Symposium (January 25-26, 2010: ISAS/JAXA Sagamihara, Japan), Small Payload Space Experiment Working Group was organized to propose the small and attractive flight experiments. The space experiment using Indian satellite SRE-II is collaboratively proceeding with India science community, and it will be launched in June-December, 2010. In this year, we conducted the manufacturing of the Japan-India Microbial Culture Unit (JIMCU) installed in the satellite. The qualification model of JIMCU has been completed the all environmental test, and the flight model is ready to be under final environmental and interface test., 形態: カラー図版あり, 共催: 日本学術会議, 著者人数: 16人, Physical characteristics: Original contains color illustrations, joint hosting: The Science Council of Japan, 資料番号: AA0064730073

In this year, we have participated in a sample-share research program of the ASI-MDS (Mice Drawer System) mission using mice through science reviews by ASI (Agenzia Spaziale Italiana)., 形態: カラー図版あり, 共催: 日本学術会議, 著者人数: 26人, Physical characteristics: Original contains color illustrations, joint hosting: The Science Council of Japan, 資料番号: AA0064730075

第25回宇宙利用シンポジウム(2009年1月14日-15日, 宇宙航空研究開発機構宇宙科学研究本部相模原キャンパス), The Twenty-fifth Space Utilization Symposium (January 14-15, 2009: ISAS/JAXA Sagamihara, Japan), Plants respond to a large variety of environmental signals, including changes in the gravity vector (gravistimulation). Previous studies have demonstrated that gravistimulation induces increases in cytoplasmic pH in root columella cells (Massa et al., 2003) and InsP3 level in inflorescence stems (Perera et al., 2001) of Arabidopsis thaliana. Recently, gravistimulation is also known to increase the cytoplasmic free calcium concentration ([Ca(sup 2+)](sub c)) in Arabidopsis seedlings (Plieth and Trewavas, 2002). However, organs responsible for the [Ca(sup 2+)](sub c) increase and the underlying cellular/molecular mechanisms remain to be solved. Previously using Arabidopsis seedlings expressing apoaequorin, a Ca(sup 2+)-sensitive luminescent protein in combination with an ultrasensitive photon counting camera, we clarified the organs where [Ca(sup 2+)](sub c) increases in response to gravistimulation and characterized the physiological and pharmacological properties of the [Ca(sup 2+)](sub c) increase (Toyota et al., 2008). When the seedlings were gravistimulated by turning 180 deg, they showed a transient biphasic [Ca(sup 2+)](sub c) increase in their hypocotyls and petioles. The second peak of the [Ca(sup 2+)](sub c) increase depended on the angle but not the speed of rotation, whereas the initial peak showed diametrically opposite characters. This suggests that the second [Ca(sup 2+)](sub c) increase is specific for changes in the gravity vector. Here, we made a control experiment; the gravi-stimulation in 1 g ground condition and the same gravi-stimulation in 1 g-flight experiments before making parabolic flight experiments to examine the properties of the second [Ca(sup 2+)](sub c) increase. We could record the [Ca(sup 2+)](sub c) increase in 1 g-flight experiments but the amplitude of the [Ca(sup 2+)](sub c) increase was diminished ca. 30 % presumably due to the vibration during the flight, but was large enough to analyze., 形態: カラー図版あり, 資料番号: AA0064297002

In this year, we have proposed the scientific collaboration using Indian satellite SRE-II, and started manufacturing a qualification model of a microbial cultivation system accommodated in the satellite. The space experiment is collaboratively proceeding with India science community, and it will be launched in September, 2009., 形態: カラー図版あり, 資料番号: AA0064297057

The space experiment using Indian satellite SRE-II is collaboratively proceeding with India science community. Our team has completed developing the flight model of the Japan-India Microbial Culture Unit (JIMCU) installed in the satellite. We are discussing about launch schedule with Indian Space Agency because the launch of their vehicle is under re-scheduling., 著者人数: 16人, 形態: カラー図版あり, Number of authors: 16, Physical characteristics: Original contains color illustrations, 資料番号: AA0065129082
