| 英文简介 | Salt and drought tolerance of plants for desert was correlated with endophytic bacteria tightly. However, the effects were still unknown. Our previous study has proved that the endophytic bacteria from desert plants were salt and alkali resistant and enhance salt and drought tolerance of their host plants. For example, the endophytic bacteria isolated from Ammodendron bifolium, an endangered species of the national grade II, increased its rate of seed germination 10 times under drought stress; the endophytic bacteria isolated from Lepidium perfoliatum, a kind of desert ephemeral plant, produced lots of exopolysaccharides; the endophytic bacteria isolated from the seeds of Caragana leucophloea was salt and alkali tolerant. In order to understanding the effects of salt and drought tolerance of endophytic bacteria from desert plants, Arabidopsis will be inoculated with about 200 endophytic bacteria we've already isolated from desert plants to screen bacterial strain which can enhance Arabidopsis salt and drought tolerance. After that the physiological response and salt and drought stress-resistance indicators, such as proline, nitrate reductase, solubility sugar, abscisic acid, betaine, malondialdehyde will be estimated under NaCl or PEG stresses on seedling development, plant growth with or without inoculation. The results will be helpful for our understanding of the physiological responses of Arabidopsis with or without inoculation with the isolates. And the adaptation mechanism of the plant stress-resistance for desert would be explored. And this will also lay a foundation for the application of endangered desert plants protection and desert ecosystems restoration. |
