| 英文简介 | The land area of arid and semi-arid agriculture is about 52.5% in China, Water shortage seriously restricts the plant growth, development, survival and distribution, plants can not initiative to avoid water damage, only via their physiological and biochemical changes to enhance their resistance and stress tolerance. Therefore, the improvement of crop drought resistance capacity and ability is the key to increase Chinese arid and semiarid region productivity of land. Previous research found that Arabidopsis thaliana HD2s (Histone deacetylase 2s) gene over expression could regulate the development of plant and reduce the sensitivity of plant to ABA, drought stress tolerance of plant is significantly improved, There is no person involved in HD2D gene family in root development and the influence of plant drought tolerance mechanism. For this purpose, in this project Arabidopsis thaliana (ecotype Columbia) wild type, HD2D gene over expression and T - insert HD2D gene silence line are used as research materials, According to the research result of HD2 gene over expression in Arabidopsis thaliana, HD2D gene and gene associate with root development expression quantity in root, root tissue microstructure difference; Specific protein interacted with HD2D protein expression differences under water stress, Take into account the related physiological drought parameter measurement, explore histone modification of plant to root development, establish the relationship between the plant response mechanism under water stress and histone covalent modification. |
