Abstract

Addition of NO(3) (-) to N-limited Selenastrum minutum during photosynthesis resulted in an immediate drop in the NADPH/NADP ratio and a slower increase of the NADH/NAD ratio. These changes were accompanied by a rapid decrease in glucose-6-phosphate and increase in 6-phosphogluconate, indicating activation of glucose-6-phosphate dehydrogenase and a role for the oxidation pentose phosphate pathway during photosynthetic NO(3) (-) assimilation. In contrast, the short-term changes in pyridine nucleotides and metabolites during photosynthetic assimilation of NH(4) (+) were not consistent with a stimulation of the oxidative pentose phosphate pathway.

摘要

在光合作用期间向氮受限的微小新月菱形藻中添加硝酸根离子（NO₃⁻）会导致烟酰胺腺嘌呤二核苷酸磷酸（NADPH）/烟酰胺腺嘌呤二核苷酸磷酸（NADP）比值立即下降，以及烟酰胺腺嘌呤二核苷酸（NADH）/烟酰胺腺嘌呤二核苷酸（NAD）比值上升速度减慢。这些变化伴随着6-磷酸葡萄糖迅速减少和6-磷酸葡萄糖酸增加，表明6-磷酸葡萄糖脱氢酶被激活，且在光合硝酸根离子（NO₃⁻）同化过程中氧化戊糖磷酸途径发挥作用。相比之下，在光合铵离子（NH₄⁺）同化过程中，吡啶核苷酸和代谢物的短期变化与氧化戊糖磷酸途径的刺激不一致。
