Tolerance to defoliation can be defined as the degree to which productivity is affected by photosynthetic area reduction. This trait was studied in grain amaranth (Amaranthus cruentus and A. hypochondriacus), which are considered to be a highly defoliation-tolerant species. The physiological and
Photosynthesis was studied in relation to the carbohydrate status in intact leaves of the C4 plant Amaranthus edulis. The rate of leaf net CO2 assimilation, stomatal conductance and intercellular partial pressure of CO2 remained constant or showed little decline towards the end of an 8-h period of
Grain amaranth (Amaranthus hypochondriacus), Yercaud local variety, was soaked overnight and germinated for 192 h taking the soaked grains as the zero time (0 h) sample. The changes in the activities of alpha- and beta-amylases, starch, sugar, protein and lysine contents during germination are
Amaranthin is the lectin present in the seeds of Amaranthus caudatus, which specifically binds the T-disaccharide (Gal beta 1,3GalNAc alpha-O-). The lectin is composed of a single type of subunit with Mr = 33,000-36,000 (Rinderle et al., 1989). Equilibrium sedimentation (Mr = 62,900) and low-angle
Uganda has one of the youngest populations in the world with about 78% of its population below 30 years of age, most of which are adolescents. The boarding school diet fed to adolescents is rich in carbohydrates and proteins but lacks adequate amounts of micronutrients to meet the adolescent RDA
Amaranthin is a homodimeric lectin that was first discovered in the seeds of Amaranthus caudatus and serves as a model for the family of amaranthin-like lectins. Though these lectins have been purified and characterized only from plant species belonging to the Amaranthaceae, evidence accumulated in
BACKGROUND
The genus Amaranthus has potential activity as a hepatoprotective agent.
OBJECTIVE
The present pharmacological investigation focuses on evaluation of the efficacy of aqueous extract of roots of Amaranthus tricolor Linn. for their protection against paracetamol (PCM) overdose induced
Sclerotium rolfsii lectin (SRL), a secretory protein from the soil borne phytopathogenic fungus Sclerotium rolfsii, has shown in our previous studies to bind strongly to the oncofetal Thomson-Friedenreich carbohydrate (Galβ1-3GalNAc-ser/thr, T or TF) antigen. TF antigen is widely expressed in many
Previous reports on the carbohydrate specificities of Amaranthus caudatus lectin (ACL) and peanut agglutinin (PNA, Arachis hypogea) indicated that they share the same specificity for the Thomsen-Friedenreich (T(alpha), Galbeta1-3GalNAcalpha1-Ser/Thr) glycotope, but differ in monosaccharide
The simple mucin-type carbohydrate antigens Tn, sialosyl-Tn, T and the 'cryptic' sialylated variant of the last represent the mucin core oligosaccharide structures that are produced in the initial steps of the mucin biosynthetic pathway. Utilizing monoclonal antibodies anti-Tn antigen (HB-Tn1),
Increased cell surface expression of the Thomsen-Friedenreich antigen (TF antigen, Galbeta1-3GalNAcalpha-) is a common feature in malignant and pre-malignant epithelia. Our previous studies have shown that dietary TF-binding lectins from peanut (Arachis hypogea) and edible mushroom (Agaricus
The most favorable conditions of pH, temperature ratio for the yielding of a protein concentrate (PC) of seed flour from Amaranthus cruentus was determined. The optimal values were: extraction pH 11, stirring time 1 h 30 min, precipitation pH 4.5 and a flour/ solvent ratio of 1:15. Obtained the PC,
The herbicides glyphosate and imazamox inhibit the biosynthetic pathway of aromatic amino acids (AAA) and branched-chain amino acids (BCAA), respectively. Both herbicides share several physiological effects in the processes triggered in plants after herbicide application that kills the plant, and
This paper reports the first ever investigation of the chemical components/composition of the seeds of Amaranthus pumilus (a threatened amaranth species) and compares the results to those of the more commonly cultivated Amaranthus hypochondriacus (Plainsman). This study clearly revealed that much
OBJECTIVE
To evaluate the phytochemical and in vitro antioxidant ability of methanolic extract and different fractions of Amaranthus graecizans subsp. silvestris (A. graecizans subsp. silvestris).
METHODS
Methanolic extract of A. graecizans subsp. silvestris was obtained by cold maceration and then
