In this research project, the molecular functions of AGP in the modification of growth anisotropy of roots induced by the gravity signal will be investigated. Gravity-responsive AGPs whose expressions are changed in response to the gravity signal and major AGPs that are expressed at high level in roots will be identified in Arabidopsis based on the expression profiles determined by microarray and quantitative-PCR analyses. The gravity-responsive and major AGPs will be visualized with a green fluorescence protein in Arabidopsis. The dynamic changes of the gravity-responsive and major AGPs in the localization and accumulation will be examined under the hypergravity condition. Furthermore, the physiological importance of the AGPs in the gravity response will be analyzed using Arabidopsis with loss-of-function mutation in the AGP genes caused by T-DNA insertion. These experiments will clarify the molecular functions of the AGPs and provide an insight into the mechanism for modification of growth anisotropy of roots in response to the gravity

内容記述 | Growth anisotropy of plant roots alters in response to the magnitude of gravity, and is regulated at least partially by cell-to-cell adhesion. Arabinogalactan-protein (AGP) is a proteoglycan found on the cell surface in higher plants. In this research project, the molecular functions of AGP in the modification of growth anisotropy of roots induced by the gravity signal will be investigated. Gravity-responsive AGPs whose expressions are changed in response to the gravity signal and major AGPs that are expressed at high level in roots will be identified in Arabidopsis based on the expression profiles determined by microarray and quantitative-PCR analyses. The gravity-responsive and major AGPs will be visualized with a green fluorescence protein in Arabidopsis. The dynamic changes of the gravity-responsive and major AGPs in the localization and accumulation will be examined under the hypergravity condition. Furthermore, the physiological importance of the AGPs in the gravity response will be analyzed using Arabidopsis with loss-of-function mutation in the AGP genes caused by T-DNA insertion. These experiments will clarify the molecular functions of the AGPs and provide an insight into the mechanism for modification of growth anisotropy of roots in response to the gravity signal. 植物の成長は重力の大きさにより制御される。微小重力環境下では植物の細胞は細く長くなり、逆に過重力環境下では太く短くなることが知られる。しかしながら、重力による細胞成長の制御機構には未だ不明な点が多い。財団法人日本宇宙フォーラムより平成18 年度から20 年度の期間で、「重力による植物根の形態変化における細胞接着因子AGP の役割」と題した研究で助成を受けている。今回は平成18 年度に実施した研究の成果を報告する。 |
