Starch biosynthesis: experiments on how starch granules grow in vivo

Carbohydrate Research, 2009
Four varieties of starch granules from potato, wheat, maize, and rice were fractionated into homogeneous 10-microm-sized ranges. The size with the largest amount of granules was reacted with ADP-[(14)C]Glc, washed, and peeled into 7-9 layers, using a controlled peeling process, involving 90:10 volume proportions of Me(2)SO-H(2)O at 10 degrees C.

Recent understanding of starch biosynthesis in cassava for quality improvement: A review

Trends in Food Science & Technology, 2019
Background Starch is the most important carbohydrate source of plant species. Both amylose and amylopectin are components of starch whose content and structures contribute to its unique properties used in food processing and industrial applications ...

Multi-objective optimization of media components for improved algae biomass, fatty acid and starch biosynthesis from Scenedesmus sp. ASK22 using desirability function approach

, 2020
In this study, we sought to improve medium composition for enhanced biomass, lipid and starch content by using response surface methodology and composite desirability function approach for the heterotrophic cultivation of Scenedesmus sp. ASK22.

The relationship between the expression pattern of starch biosynthesis enzymes and molecular structure of high amylose maize starch.

Carbohydrate Polymers, 2020
Two high amylose (HAM) inbred lines with apparent amylose contents of 55 % and 62 %, respectively, were selected to explore the relationship between molecular structure and gene expression of starch-synthase involved enzymes.

The Biosynthesis of Starch Granules

Biomacromolecules, 2001
Although composed simply of glucose polymers, the starch granule is a complex, semicrystalline structure. Much of this complexity arises from the fact that the two primary enzymes of synthesis-starch synthase and starch-branching enzyme-exist as multiple isoforms.

The Role of Pullulanase in Starch Biosynthesis, Structure, and Thermal Properties by Studying Sorghum with Increased Pullulanase Activity

Starke (Weinheim), 2019
Pullulanase is a starch debranching enzyme involved in starch biosynthesis, but its function in starch biosynthesis is not fully established. This study aims to understand its function by analyzing a sorghum variety (SbPUL-RA) with increased pullulanase ...

Proteomic Analysis of Starch Biosynthesis in Maize Seeds

Starke (Weinheim), 2019
Maize starch is an important agricultural commodity that serves as food, feed, and a raw material for industrial purposes. Starch biosynthesis in maize endosperm is an essential process for maize productivity under changing environmental conditions ...

CO2-Responsive CCT Protein Stimulates the Ectopic Expression of Particular Starch Biosynthesis-Related Enzymes, Which Markedly Change the Structure of Starch in the Leaf Sheaths of Rice.

Plant and Cell Physiology, 2019
CO2-responsive CCT protein (CRCT) is suggested to be a positive regulator of starch biosynthesis in the leaf sheaths of rice, regulating the expression levels of starch biosynthesis-related genes.

Biosynthesis of Reserve Starch

2015
Plants have developed two distinct starch biosynthetic systems composed of over 30 kinds of enzymatic reaction network in photosynthetic and non-photosynthetic cells. Higher plants have also evolved a process in which cells can accumulate huge amounts of starch as granules inside the amyloplast of the reserve organs.

Regulation of Starch Biosynthesis

2006
Transient or long-term storage of photosynthate in starch granules can be considered as the last step of eukaryotic photosynthesis. Storage of glucose into structures larger than the size of an individual bacterial cell is slowly uncovering as an exceedingly complex mechanism, which distinguishes the chloroplast from its ancestor prochloron or ...
