The growth of corn (Zea mays) roots and barley (Hordeum vulgare) coleoptiles is sensitive to the presence of external d-glucosamine and d-galactose. In order to investigate this effect, tissues were fed the radioactive monosaccharides at concentrations that ranged from those that were strongly
1. Radioactivity from d-[l-(14)C]glucosamine is incorporated into ethanol-insoluble compounds of high molecular weight in a number of plant tissues, including roots of corn (Zea mays), callus cells of sycamore (Acer pseudoplatanus), axenic cultures of duckweed (Lemna minor) and germinating seedlings
Abscisic acid (ABA) regulates leaf growth and transpiration rate of plants exposed to salt stress. Despite the known fact that cell dehydration is instrumental for the modulation of ABA concentrations when NaCl is high in the external environment, it was never tested as to whether sodium (Na) or
d-Glucosamine-1-(14)C was rapidly taken up from aqueous solution by both excised bean (Phaseolus vulgaris) and corn (Zea mays) root tips. The labeled glucosamine did not accumulate in the tissues, however, but was metabolized to N-acetyl-d-glucosamine, N-acetyl-d-glucosamine phosphates, and uridine
We purified and characterized a lectin from the corn coleoptyle (Zea mays). The lectin (CCL) was purified by affinity chromatography on a Lactosyl-Sepharose 4B column. It is a glycoprotein of 88.7 kDa, composed mainly by glutamic, aspartic, glycine, and Ser residues; in a minor proportion, it
Type 2 diabetes mellitus (T2DM) impairs hepatic clearance of atherogenic postprandial triglyceride-rich lipoproteins (TRLs). We recently reported that livers from T2DM db/db mice markedly overexpress the heparan sulfate glucosamine-6-O-endosulfatase-2 (SULF2), an enzyme that removes 6-O sulfate
Ustilago maydis is an edible parasitic basidiomycete, which specifically infects corn (Zea mays) and teocintle (Z. diploperennis). To characterise the interaction between the basidiomycete and its host organism, we tested the effect of plant lectins with well-known sugar specificity on the growth
The objectives of this study were: 1) to identify and characterize ewe oviductal secretory proteins (OSP) de novo synthesized during the estrous cycle; 2) to examine the effect of estrogen (E) and progesterone (P) on synthesis of OSP; and 3) to determine synthesis of OSP by ampulla (A) and isthmus
