Role Of Phosphoglucan Phosphatases In Regulating Starch Degradation In Plants
Starch is the major carbohydrate reserve in plants. Sugars are assimilated into storage granules during photosynthesis and released for continual growth at night from the chloroplast. Breakdown of leaf starch is initiated through reversible glucan phosphorylation by novel dikinases and phosphatases …

The control of starch degradation in Arabidopsis thaliana leaves at night
… how Arabidopsis thaliana plants control starch degradation at night. Starch is the major energy reserve in Arabidopsis. It is broken down at night to maintain growth and metabolism of the plant, when photosynthesis is not possible. The rate of starch degradation follows a linear pattern …

Alpha-Glucan, Water Dikinase and the Control of Starch Degradation in Arabidopsis thaliana Leaves
… water dikinase (GWD) in the control of starch degradation in Arabidopsis thaliana leaves. Starch is degraded at night in Arabidopsis leaves to provide carbon for metabolism and growth. The rate of starch degradation is constant through the night and is precisely regulated such that …

The role of interfacial and 'entropic' enzymes in transitory starch degradation : a mathematical modeling approach
… algae store carbon in the form of transitory starch on a diurnal basis. The turnover of this glucose polymer is tightly regulated and timely synthesis as well as mobilization is essential to provide energy for heterotrophic growth. Especially for starch degradation, novel enzymes and …

Mechanisms of cytokinin action
… on these systems. 5. Kinetin increased gross starch degradation and sugar utilization in leaf discs floated for 3 days in the light or dark whether or not sucrose was present in the floating medium. Since kinetin induced a change in neutral sugars prior to a change in starch content of the …

Study of starch debranching enzymes in developing wheat kernels
Starch debranching enzymes, which specifically hydrolyse a-1,6-glucosidic bonds in glucans containing both a-1,4 and a-1,6 linkages, are classified into two types: isoamylase (EC. 3.2.1.68) and limit dextrinase (EC. 3.2.1.41). The starch debranching enzymes are primarily involved in starch …

Development of genome editing in potato and tobacco
… Under these conditions, phosphorylated starch breaks down into reducing sugars which, during frying, react with amino acids to form acrylamide, a potential carcinogen (Mottram et al., 2002; Stadler et al., 2002; Bhaskar et al., 2010). Acrylamide formation in potato chips and French fries …

The Effect of Lipid/Hydrocolloid Coatings on the Postharvest Storage Quality of 'Golden Delicious' Apples
… of the apples along with a lower (P<0.0083) starch degradation rate. The treatment groups also significantly (P<0.0083) maintained the malic acid level in the apple. There were no significant differences (P>0.0083) among the groups with regard to soluble solids and fresh weight loss. …

Improving the Understanding of Factors Driving Rumen Fermentation
… technique to rank livestock feeds based on their starch degradability. This experiment also compared the starch degradation rates estimated by the in vitro method to the rates estimated by a traditional in situ method using sheep. A relationship between the degradation rates determined by these …

Grain hardness and slow dry matter disappearance rate in barley
… maladies caused by the rapid breakdown of barley starch in the rumen. The development of slower degrading barley for ruminants may alleviate health problems associated with barley grain consumption. Selection for hard endosperm may result in slower starch degradation and improved feed quality. The …

Comparative analysis of desiccation responses in three Xerophyta species at two stages of seedling development
… as vacuolation, chloroplast centralization, and starch degradation, typically observed in adult tissues, were also prevalent in the two-leaf seedlings of X. elegans and X. schlechteri. Notably, complete disassembly of the thylakoid membranes was observed in X. schlechteri but not in X. elegans. …

Interaction between respiratory carbon flow and photosynthetic light harvesting in the green alga, selenastrum minutum
… carbon flow as measured by CO2 release and/or starch degradation. These treatments were further subdivided on the basis of their ability to cause a state transition. Class 1 treatments included NH4+ assimilation by N-limited cells, anaerobic treatment, and uncoupling with CCCP and all resulted …

Glycerol from novel strains of halophytic microalgae
… volume due to water efflux from the cell. The starch and glycerol pools of Dunaliella T35 were investigated after 24 h exposure to 1.0 and 4.0 M NaCl in dark and light regimes in order to investigate how starch degradation contributed to glycerol production. In 1.0 M NaCl, the amount of starch …

Molekulare Untersuchungen zum Stärkeabbau in vegetativen Pflanzenteilen
In der vorliegenden Arbeit wurden cDNAs, kodierend für bisher unbekannte stärkeabbauende Enzyme, aus Kartoffel isoliert und funktionell analysiert. Die Isolation der cDNAs erfolgte mit Hilfe eines Systems, welches sich der funktionellen Expression von cDNA-Bibliotheken in E. coli bediente. Die mit …

Incorporation of mushroom powder into cereal food products
… of mushroom powder significantly decreased the starch content, the extent of starch degradation and the area under the curve (AUC) of reducing sugars released during the digestion of pasta, while it also increased the total phenolic content and antioxidant capacities of samples. Powder from …

Understanding the Role of Extrusion Processing Parameters on Functional Properties of Distillers Dried Grains Extruded Using Single and Twin Screw Extruder
… increase in temperature this might be due to starch degradation and dextrinisation at higher temperature. Peak load increased with increase in RE. This can be ascribed to more starch content and thicker cell walls, a* value decreased with increase in temperature. This could be because at …
