Maize (Zea mays L.) callus cultures cannot use mannose as a sole carbohydrate source, but can utilize fructose for that purpose. Phosphomannose isomerase (PMI) can convert mannose to fructose. Transgenic maize plants were obtained by selecting polyethylene glycol (PEG)-mediated transformed
BACKGROUND
In a recent report, the carbohydrate-binding specificities of the plant lectins Galanthus nivalis (GNA) and the closely related lectin from Zea mays (GNAmaize) were determined by glycan array analysis and indicated that GNAmaize recognizes complex-type N-glycans whereas GNA has
When green leaves of spinach (Spinacia oleracea L.) were surveyed for the presence of hexokinases which utilize glucose, fructose and-or mannose as a substrate, four kinases could be distinguished by their order of elution during chromatography on diethylaminoethyl (DEAE)-cellulose: (i) a hexokinase
The effect of D-mannose (Man) on plant cells was studied in two different systems: Arabidopsis roots and maize (Zea mays) suspension-cultured cells. In both systems, exposure to D-Man was associated with a subset of features characteristic of apoptosis, as assessed by oligonucleosomal fragmentation
The role of hexokinase in carbohydrate degradation in isolated, intact chloroplasts was evaluated. This was accomplished by monitoring the evolution of 14CO2 from darkened spinach (Spinacia oleracea), maize (Zea mays) mesophyll, and Chlamydomonas reinhardtii chloroplasts externally supplied with
BACKGROUND
The aim of our work was to investigate the effects ofω -3 polyunsaturated fatty acids on apoptosis and granzyme B, perforin, and cation-independent mannose 6-phosphate/insulin-like growth factor receptor (CI-MPR) expression of intestinal epithelial cells of chronic rejection after small

The effects of mannose (Man) and glucose (Glc) on central metabolism, proteolysis, and expression of the root starvation-induced protease (RSIP; F. James, R. Brouquisse, C. Suire, A. Pradet, P. Raymond [1996] Biochem J 320: 283-292) were investigated in maize (Zea mays L. cv DEA) root tips. Changes
Male Sprague-Dawley rats were given daily oral doses of either corn oil (control), 80 mg/kg nafenopin (NAF), 50 mg/kg methylclofenapate (MCP), 50 mg/kg Wy-14,643 (WY) or 250 mg/kg clofibric acid (CA) for 7 days. All four compounds increased relative liver weight and produced hepatic peroxisome
The effect of sugars and metabolic inhibitors on the elongation of Zea mays root segments was analyzed by a rhizometer which records the elongation of each of 32 root segments at the same time. Galactose suppressed the acid-enhanced rapid elongation after a lag period of 1.5 hours, but it did not
The major auxin-binding protein (ZmERabp1) from maize (Zea mays L.) has been structurally characterized. We determined the position of a disulfide bridge in ZmERabp1 by mass-spectrometric analysis. We show that Cys2 and Cys61 are covalently linked and that residue Cys155 bears the free sulfhydryl
In etiolated corn (Zea mays L.) and etiolated pea (Pisum sativum L.) seedlings, a gravitropic stimulation induces the deposition of callose. In the corn coleoptiles this occurs within 5 min of gravity stimulation, and prior to the beginning of curvature. Both gravitropic curvature and callose
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
Treatment of whole plants with jasmonic acid methyl ester induces lectin activity in leaves of Oryza sativa, Hordeum vulgare, Triticum vulgare, Secale cereale and Zea mays. Purification and characterization of the lectins revealed that they all have a very similar molecular structure and
To cause disease in maize, the biotrophic fungus Ustilago maydis secretes a large arsenal of effector proteins. Here, we functionally characterize the repetitive effector Rsp3 (repetitive secreted protein 3), which shows length polymorphisms in field isolates and is highly expressed during
