Evolution of Endosperm Starch Synthesis Pathway genes in the Context of Rice: Oryza sativa) Domestication
… of evolutionary change. The rice endosperm starch biosynthetic pathway is one of the most thoroughly characterized biosynthesis pathways in plants, and starch is a trait that has evolved in response to strong selection during rice domestication and subsequent crop improvement. In this study, …

Redox-regulation of starch and lipid synthesis in leaves
… pentose phosphate cycle, NADPH export and ATP synthesis in response to light. The aim of the present thesis was to investigate whether a similar mechanism is also regulating carbon storage in leaves. Previous studies have shown that the key-regulatory enzyme of starch synthesis, ADPglucose …

Regulation of growth and storage product metabolism in cultured kernels of maize
… and grain yield are functions of endosperm starch accumulation. In vitro seed culture was used to study the influence of assimilate supply on the growth and composition of maize endosperm and to determine how various metabolic events in developing endosperm are related to starch …

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 NAM-B1 transcription factor and the control of grain composition in wheat
… from flag leaf senescence. In RNAi plants starch synthesis enzymes were less active during the middle of grain filling than in control plants, potentially resulting in the reallocation of photosynthate to the stems as water soluble carbohydrates. Many of the putative NAM-B1 target genes …

The relevance of adenylate levels and adenylate converting enzymes on metabolism and development of potato (Solanum tuberosum L.) tubers
… significant amounts of ATP, like amino acid or starch synthesis, and an activation of processes that produce ATP, like respiration and an immense increase in the surface-to-volume ratio. To identify extracellular enzymes involved in adenylate conversion, green fluorescent protein and activity …

Spatial patterns of wheat grain composition in relation to nutritional quality and processing properties
… breadmaking, derives from grinding of the grain starchy endosperm. Several studies have demonstrated that the endosperm tissue shows significant inhomogeneity in its chemical composition, with both quantitative and qualitative patterns of tissue distribution observed for all its main storage …

Synthesis and characterization of starch-based cationic flocculants for harvesting microalgae.
… was to develop a procedure to synthesize starch-based cationic flocculants which would be renewable, biodegradable, and non-toxic with harvest performance comparable with or better than commercial flocculants. The procedure involves cationization reaction between starch and …

A Theoretical Approach to Guiding Biotechnological Improvement of Crop Photosynthetic Efficiency
… photoprotection to increase efficiency of photosynthesis of leaves in the shade, could increase Ac by ca. 15%, and by more at lower temperatures. In order to expedite the identification of targets for genetic manipulations for higher net photosynthetic CO 2 uptake rates, a dynamic model of …

Functional analysis of the sucrose synthase gene family in Arabidopsis thaliana
… (Fu and Park, 1995), provides substrates for starch synthesis (Zrenner et al., 1995), and supplies UDP-glucose for cell wall synthesis (Haigler et al., 2001). Analysis of the Arabidopsis genome identifies six Susy isoforms. The expression of these isoforms was investigated using …

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 …

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 …

Genotypic variation in Actinidia deliciosa fruit size and carbohydrate content
… correlation between at-harvest dry matter and starch content, and soluble solid concentration and flavour when fruit are eating ripe. This suggests that carbon accumulation strongly influences the development of kiwifruit taste. The overall aim of the present study was to determine what factors …
