Amaranth, soybean and maize were screened for proteins and their nutritional value. Isopropanol-soluble protein and buffer-soluble protein fractions were extracted from seeds and separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). The comparison of the identity and differences between investigated plants was carried out by the obtained SDS-PAGE electrophoretic pat...

Glyphosate-resistant Palmer amaranth from Georgia (GA), USA, possesses multiple copies of the gene that encodes 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS), the enzyme target site of this herbicide. The cloned plants of glyphosate-resistant and glyphosatesusceptible Palmer amaranth biotypes from Mississippi (MS), USA, and GA were evaluated for glyphosate injury (digital imaging) in leaf...

The wide distribution of Palmer amaranth (Amaranthus palmeri) in the southern US became a serious weed control problem prior to the extensive use of glyphosate-resistant crops. Currently glyphosate-resistant populations of Palmer amaranth occur in many areas of this geographic region creating an even more serious threat to crop production. Investigations were undertaken using four biotypes (one...

BACKGROUND AND AIMS Accounting for the acclimation of respiration of plants to temperature remains a major problem in analysis of carbon balances of plants and ecosystems. Translocation of carbohydrates out of leaves in the dark requires energy from respiration. In this study relationships between the responses of leaf respiration and translocation to temperature are examined. METHODS Direct ...

The genotyping by sequencing (GBS) method has become a molecular marker technology of choice for many crop plants because of its simultaneous discovery and evaluation of a large number of single nucleotide polymorphisms (SNPs) and utility for germplasm characterization. Genome representation and complexity reduction are the basis for GBS fingerprinting and can vary by species based on genome si...

The photocatalytic degradation of dyes (alizarin red S, amaranth, congo red, and rhodamine B) present in wastewater was performed with UV lamp. catalysts employed for this investigation were ZnO, TiO2, SnO2. kinetic studies followed first order reaction. ZnO found to be most efficient photo-catalyst degrading these dyes. optimal result alizarin S k = 0.2118 min?1, t1/2 3.27 min, R2 0.7998, amar...

This study developed a method for discriminating between Andean indigenous crops and hybrid crops, using total lipid composition, fatty acid profiles, statistical comparison. Cluster analysis Principal Component Analysis (PCA) revealed the standard fingerprints of gas chromatography-FID primary acids related to loadings, which shows explained variance (91.4–99.5%) 32 cultivars, including quinoa...

Abstract Amaranth imprinted nanoparticles were prepared by two-phase mini emulsion polymerization of hydroxyethyl methacrylate and ethylene glycol dimethacrylate using acrylamide methacrylic acid as functional monomers. The amaranth non-imprinted nanoparticle was with the same procedure without amaranth. attached on chip surface modified allyl mercaptan. surfaces plasmon resonance (SPR) sensor ...
