| 中文摘要: |
| ：干旱胁迫是作物光合作用和生长的主要限制因子。利用较少的水分生产较多的光合干物质,是提高作物水分利用效率的关键。因此,深入研究光合酶的调控机制,利用基因工程改良光合酶基因的表达和活性,提高作物的光合效率,是实现高光效和高WUE相结合的重要途径。本文就水分胁迫下作物光合作用与抗旱节水的关系研究,以及光合固定CO2、蔗糖和淀粉代谢关键酶的生物学结构和功能的研究进展进行综述,以期为作物光能高效利用及抗旱节水研究提供有用信息。 |
| 英文摘要: |
| The water deficit is a major abiotic factor limiting crop photosynthesis and growth．Producing more photosynthetic dry matter with less water is the key to increase crop WUE．Therefore?photosynthetic efficiency could be increased through improving the enzymic genes expression and activity with genetic engineering by investigating the regulating mechanism of the enzymes．This is an important approach to realize the combination of higher photosynthetic efficiency and higher WUE．The present paper reviewed the research progress concerning the relation between crop photosynthesis and resisting drought and saving water under drought stress and the biological structure and function of the key enzymes of crop fixing CO2 and of sucrose and starch metabolite．The purpose is to provide useful information about efficient radiation use and drought resistance and water saving in crops． |
