This report serves to document research conducted under a cooperative agreement between ARS and Iowa State University. Specific objectives of this research project are to (1) Develop and characterize hybrids using normal and waxy GEM lines to produce hybrids with improved yield and starch-ethanol conversion efficiency to increase ethanol yield; and (2) Develop healthy foods and healthy food ing...
Cereal starch production forms the basis of subsistence for much of the world's human and domesticated animal populations. Starch concentration and composition in the maize (Zea mays ssp mays) kernel are complex traits controlled by many genes. In this study, an association approach was used to evaluate six maize candidate genes involved in kernel starch biosynthesis: amylose extender1 (ae1), b...
Cereal Chem. 81(4):527–532 Differential scanning calorimetry (DSC) is used routinely to screen for starch thermal properties. In early generations of line development, the established analysis separately evaluates starch extracted from five, single corn kernels. A thermal property trait carried by a recessive gene would appear 25% of the time; thus, if five separate kernels were evaluated, the ...
We investigated the evolutionary dynamics of duplicated copies of the granule-bound starch synthase I gene (GBSSI or Waxy) within polyploid Spartina species. Molecular cloning, sequencing, and phylogenetic analyses revealed incongruences between the expected species phylogeny and the inferred gene trees. Some genes within species were more divergent than expected from ploidy level alone, sugges...
Two origin of starch – maize and wheat were tested by using four non lactating cows with rumen and duodenal Tcannules in the experiment. Cr2O3 was used as a marker of nutrient flow to the duodenum. Cows were fed diets consisting of, %: forage 70, maize and/or wheat meal 27 and/or 29, soyabeanmeal 2 and vitamix S 1, on dry matter basis. Starch origin did not affect ruminal fermentation significa...
Starch synthesis is a key process that influences crop yield and quality, though little is known about the regulation of this complex metabolic pathway. Here, we present the identification of ZmbZIP91 as a candidate regulator of starch synthesis via co-expression analysis in maize (Zea mays L.). ZmbZIP91 was strongly associated with the expression of starch synthesis genes. Reverse tanscription...
The objective of this research was to determine the conversion efficiency of proso millet to ethanol compared to corn in a bench-scale dry-grind procedure. Seven proso millet cultivars and six advanced breeding lines containing waxy starch were fermented with Saccharomyces cerevisiae and ethanol production was compared with normal corn and “highly fermentable” corn. The highly fermentable corn ...
During thermal treatment of starch-based liquid food products, many coupled phenomena occur at different scales. Heat transfer affects local temperature evolution, which determines starch transformation (swelling and eventually amylose release and/or granules breakage). This modifies the rheology, in turn fluid flow heat transfer. two-way coupling flow, was previously simulated exchangers by Co...
