 note = {Root systems are responsible for the acquisition of water and nutrients, and they enable plants to become established in heterogeneous environments. Root hydrotropism is a response to a moisture gradients, which is considered to be important for drought avoidance. Despite the difficulty of separating hydrotropism from gravitropism on Earth, our previous results suggested that root gravitropism interferes hydrotropism and that auxin plays pivotal role in both tropisms. Furthermore, both hydrotropism and gravitropism are found to be accompanied with asymmetric expressions of auxin-inducible genes. However the interacting mechanism has not been figured out yet. We proposed to use the microgravity environment to separate hydrotropism from gravitropism and dissect respective mechanisms in cucumber roots, which has been approved as a forthcoming spaceflight experiment by International Space Life Science Working Group in 2004. In this presentation, our recent ground-based experiments for demonstration of cucumber root hydrotropism in space are described., 資料番号: AA0063706117},
