Zeins, the predominent storage proteins in maize endosperm, are encoded by multiple genes and gene families. However, only a few transcriptional factors for zein gene regulation have been functionally characterized. In this study, a MADS-box protein, namely ZmMADS47, was identified as an Opaque2 (O2) interacting protein via yeast two-hybrid screening. The N-terminal portion of ZmMADS47 contains...
The maize opaque2 (o2) mutant has a high nutritional value but it develops a chalky endosperm that limits its practical use. Genetic selection for o2 modifiers can convert the normally chalky endosperm of the mutant into a hard, vitreous phenotype, yielding what is known as quality protein maize (QPM). Previous studies have shown that enhanced expression of 27-kDa γ-zein in QPM is essential for...
BACKGROUND Foams are high porosity and low density materials. In nature, they are a common architecture. Some of their relevant technological applications include heat and sound insulation, lightweight materials, and tissue engineering scaffolds. Foams derived from natural polymers are particularly attractive for tissue culture due to their biodegradability and bio-compatibility. Here, the foam...
Due to the limited regenerative capacity of natural human myocardium, 3D printing cyclic polyester poly (glycerol sebacate) (PGS) offers a promising alternative produce scaffolds (cardiac patches) for cardiac tissue engineering. Since printability and subsequent thermal crosslinking pure PGS without any modification or additives are challenging, PGS-zein-salt-based process is developed in this ...
The studies of Gorter (1), Hughes and Rideal (2), Neurath (3), and Langmuir (4) have shown that proteins are capable of forming surface films of a thickness and area independent of the diameter of the molecule. Depending on the pH and salt concentration of the solution upon which the protein is spread, the surface area may be more than 5 times greater than that to be expected from a monolayer o...
Zein is the major storage protein of the endosperm of maize kernels. When this alcohol-soluble protein is subjected to SDS polyacrylamide gel electrophoresis, it is resolved into four fractions of different molecular weight: 10, 14, 20 and 22 kilodaltons (kd). Each fraction is heterogeneous with respect to isoelectric pH. For example, the 20 kd fraction contains at least seven subfractions as r...
