| 摘 要： | 戊糖磷酸途径是植物体中糖代谢的重要途径，主要生理功能是产生供还原性生物合成需要的NADPH，可供核酸代谢的磷酸戊糖以及一些中间产物可参与氨基酸合成和脂肪酸合成等。葡萄糖-6-磷酸脱氢酶和6-磷酸葡萄糖酸脱氢酶是戊糖磷酸途径的两个关键酶，广泛的分布于高等植物的胞质和质体中。本文综述了植物戊糖磷酸途径及其两个关键酶的分子生物学的研究进展，讨论了该途径在植物生长发育和环境胁迫应答中的作用。

| Abstract: | The pentose phosphate pathway in plant is a very important metabolic pathway which supplies the major sources of reduced nicotinamide adenine dinucleotide phosphate (NADPH) and the ribulose 5-phosphate, ribose 5-phosphate and erythrose 5-phosphate involved in synthesis ofnucleotides, aromatic amino acids and fatty acids in non-photosynthetic tissues. This paper mainly reviews the advances of research on plant pentose phosphate pathway and its key enzymes: glucose-6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase. Its possible functions involved in plant development or responding to environmental stresses are discussed. |
