Effect of Anoxia on Carbohydrate Metabolism in Rice Seedlings

Abstract: The metabolism of carbohydrates was investigated in rice (Oryza sativa 1.) seedlings grown under anoxia. Two phases can be recognized in the utilization of carbohydrates: during the first days of germination under anoxia, the metabolism of sugars is mainly degradative, whereas after the induction of a-amylase (EC 3.2.1.1) has taken place, the increased presence of glucose and sucrose indicates that both starch degradation and sucrose synthesis operate. The analysis of the enzymes involved in carbohydrate metab… Show more

“…3), which is consistent with the previous experimental suggestions (Mohanty et al, 1993;Guglielminetti et al, 1995). The in silico analysis also confirmed the recycling of UTP to SUS, which occurs through the nucleoside diphosphate kinase (NDPK) and the UDP-Glc pyrophosphorylase (UGPP).…”

“…The in silico analysis also confirmed the recycling of UTP to SUS, which occurs through the nucleoside diphosphate kinase (NDPK) and the UDP-Glc pyrophosphorylase (UGPP). Although the supply of UTP to SUS from UGPP was proposed by Guglielminetti et al (1995), they did not clearly reveal the source of inorganic pyrophosphate (PPi); rather, they just hypothesized its origin from PPi-dependent phosphofructokinase (PFP). In this regard, our simulation results suggested that the PPi could be produced toward the gluconeogenesis direction via reactions catalyzed by either PFP or pyruvate orthophosphate dikinase (PPDK), forming a substrate cycle in glycolysis.…”

“…The glucose, fructose and sucrose contents of the samples were assayed by the coupled enzymatic assay method, which measures the increase in A 340 , as described by Guglielielminetti et al (1995). The fresh weight of the frozen samples was measured, and then the samples were extracted with 80% ethanol at 80ºC.…”
