植物在经受干旱胁迫时,通过细胞对干旱信号的感知和传导,调节基因表达,产生新蛋白质,从而引起大量形态、生理和生化上的变化.干旱胁迫对植物在细胞、器官、个体、群体等水平上的形态指标有显著影响,也会影响其光合作用、渗透调节、抗氧化系统等生理生化指标.植物对干旱胁迫的分子响应较复杂,包括合成一些新的基因如NCED、dehydrin基因和CBF、DREB等转录因子.另外,干旱胁迫还能造成蛋白质组学的变化.参52 |

When plants are suffered by drought stress, they can through cells apperceive and transmit drought signal, regulate gene expression and produce new proteins, so as to cause many morphological, physiological and biochemiscal changes. Drought stress significantly and morphologically affects cells, organs, individuals and populations of plants, and also physiologically and biochemically impacts their photosynthesis, osmoregulation and antioxidant system. Molecular responses of plants to drought stress are complicated, which induces the syntheses of some new genes, such as NCED and dehydrin genes, and CBF and DREB transcription factors. Moreover, drought stress can also induce some changes in proteomics. Ref 52. |
