| Research Abstract |
In this project, changes of plant morphology of Soybean under pseudo-microgravity (PMG) environment produced by a 3-D clinostat were compared with ground-grown control samples. As a result, root length, number of lateral root and proliferation activity of root cells for PMG-grown soybean were increased. These observation were close relationship to gene expressions between arf8 and pgp1. Furthermore, the number of root nodule primordium on PMG-grown sample was increased. To develop an in-situ method for measuring root elongation by capacitance detection, two electrodes; one of them is attached to the stem and the other is inserted in to the soil. The capacitance which changes with depth of root elongation was successfully detected in dry soil and wet soil.
