A new allele of the 27-kD zein locus in maize has been generated by interchromosomal recombination between chromosomes of two different inbred lines. A continuous patch of at least 11,817 bp of inbred W64A, containing the previously characterized Ra allele of the 27-kD zein gene, has been inserted into the genome of A188 by a single crossover. While both junction sequences are conserved, sequen...

Formation of gold nanoparticles in aqueous ethanol in the presence of pyridine-functionalized single-chain nanoparticles allows for the fast and highly sensitive colorimetric detection of zein corn protein.

Parental imprinting describes the phenomenon of unequivalent gene function based on transmission from the female or male parent. We have discovered parental imprinting of an allele of the dzr1 locus that posttranscriptionally regulates the accumulation of 10-kDa zein in the maize endosperm. The imprinted allele of MO17 inbred origin, dzr1 + MO17, conditions low accumulation of the 10-kDa zein a...

Natural pharmaceutical ingredients have been widely used in recent decades due to their safety and biocompatibility. Zein, a plant-derived natural protein, has several advantages over other synthetic polymers bone tissue engineering (BTE). This study of zein protein focuses more on its application BTE as potential biopolymer material scaffold development. The use shown benefits the production s...

Removal of spilled petroleum oil from water bodies using hydrophobic porous absorbent has garnered considerable attention due to the simplicity, large-scale adaptability and robustness process. However, use nonbiodegradable synthetic during cleanup raised a secondary concern such as generating plastic pollutants that can accumulate in marine other ecosystems. To encounter this potential hazard,...

Seed protein of foxtai1 and proso millets were fractionated into polypeptides that were analyzed for their major protein, prolamin, and the NHrterminal amine acid seqllenccs of the proteins were determined. The proteins extracted from foxtail and proso millets were 64.1% and 80.0% prolamin, respectively. The polypeptides of the prolamins were classMed into two groups. The majer polypeptides of ...

We show that maize storage protein translocation across microsomal membranes is mediated by signal recognition particles (SRPs) similar to those described in animal systems (Dobberstein, B. (1978) Hoppe-Seyler's Z. Physiol. Chem. 252, 955-962; Walter, P., and Blobel, G. (1980) Proc. Natl. Acad. Sci. U. S. A. 77, 7112-7116). We have prepared a high salt extract from endosperm cell homogenates, f...

The strength and the character of the binding of 12 organic solvents to the corn protein zein was determined by preparing zein-coated carbon stationary phase and by measuring the retention of solvents on a high-performance liquid chromatographic column filled with this stationary phase. The relationship between the physicochemical parameters and binding characteristics of solvents was elucidate...
