Studies on the oxidative and calcium signaling mechanisms in plant cells under cell-expanding conditions 伸長成長時の植物細胞における酸化的およびカルシウム情報伝達機構に関する研究 グエン　ホアン, チュン　ヒエウ metadata only access 植物 環境応答 オーキシン カルシウム情報伝達 活性酸素 Auxin and water are two important factors for the growth of plant cells, particularly for the cell expansion. In the natural environment, plants frequently sense and respond to the environmental changes, by altering the level of auxin and water status. The production of reactive oxygen species (ROS) and the increase in intracellular calcium concentration ([Ca2+]) are key mediators of the plant responses to various stimuli. In the present study, the coordination between ROS and Ca2+ signaling under cell-expanding conditions in plant cells were investigated; specifically, a study on the cell responses to exogenous auxin (indole-3-acetic acid, IAA) was conducted in transgenic rice cells harboring protein-based Ca2+ indicator (aequorin) in cytosol, whereas, a study on the cell responses to Hypo-OS was conducted in two transgenic tabacco (BY-2) cells expressing the aequorin gene in either cytosol or nucleus. eng thesis https://kitakyu.repo.nii.ac.jp/records/661 27101甲第007号 博士(学位) 2018-09-25 北九州市立大学
