Earlier we isolated a threonine-rich extensin from maize (Zea mays). Here, we report that maize cell suspension cultures yield a new extensin rich in histidine (HHRGP) that also has characteristics of arabinogalactan proteins (AGPs). Thus, chymotryptic peptide maps of anhydrous hydrogen fluoride

Reduced expression of selected FASCICLIN-LIKE ARABINOGALACTAN PROTEIN genes associates with the abortion of kernels in field crops of Zea mays (maize) and of Arabidopsis seeds.

Abortion of fertilized ovaries at the tip of the ear can generate significant yield losses in maize crops. To investigate the mechanisms involved in this process, 2 maize hybrids were grown in field crops at 2 sowing densities and under 3 irrigation regimes (well-watered control, drought before

The structure of the arabinogalactan obtained from the buffer-homogenate of Zea mays L. (hybrid B73 x Mo17) shoots has been studied. The purified polysaccharide was investigated by methylation analysis before and after controlled acid hydrolysis. Arabinogalactan-1 consists of arabinose, galactose,

Cytochemical identification of arabinogalactan protein in the outer epidermal wall of maize coleoptiles.

Artificial carbohydrate antigen (Yariv reagent), fluorescence-labeled α-L-fucose-binding lectin, and β-D-galactose-binding lectin were used to localize arabinogalactan protein in sections of maize (Zea mays L.) coleoptiles. All three probes bind to cell walls of vascular tissue and the outer

Purification and Partial Characterization of a Hydroxyproline-Rich Glycoprotein in a Graminaceous Monocot, Zea mays.

Graminaceous monocots generally contain low levels of hydroxyproline-rich Glycoproteins (HRGPs). As HRGPs are often at the cell surface, we used the intact cell elution technique (100 millimolar AlCl(3)) to isolate soluble surface proteins from Zea mays cell suspension cultures. Further

Spatio-temporal diversification of the cell wall matrix materials in the developing stomatal complexes of Zea mays.

UNASSIGNED The matrix cell wall materials, in developing Zea mays stomatal complexes are asymmetrically distributed, a phenomenon appearing related to the local cell wall expansion and deformation, the establishment of cell polarity, and determination of the cell division plane. In cells of

Secreted slime isolated from the incubation medium of Zea mays roots maintained axenically contains fucose, arabinose, xylose, galactose, and glucose as the major monosaccharides. The slime preparation contains low levels (3% weight/weight [w/w]) of uronic acids. Methylation analysis reveals an

Pectic polysaccharide from corn (Zea mays L.) effectively inhibited multi-step mediated cancer cell growth and metastasis.

Corn pectic polysaccharide (COPP) inhibited galectin-3 mediated hemagglutination at Minimum Inhibitory Concentration (MIC) of 4.08 μg/mL as opposed to citrus pectin (25 μg/mL), a well known galectin-3 inhibitor and lactose (4.16 μg/mL)--sugar specific to galectin-3. COPP effectively (72%) inhibited

Comparative analysis of the phytocyanin gene family in 10 plant species: a focus on Zea mays.

Phytocyanins (PCs) are plant-specific blue copper proteins, which play essential roles in electron transport. While the origin and expansion of this gene family is not well-investigated in plants. Here, we investigated their evolution by undertaking a genome-wide identification and comparison in 10

Zea mays (maize) pollen exines have been purified with the use of differential centrifugation and sucrose gradients, followed by mild detergent and high salt treatment. The final exine fraction is highly purified from other organelles and subcellular structures as assayed by transmission electron

The extensin family is a diverse group of hydroxyproline-rich glycoproteins located in the cell wall and characterized by repetitive peptide motifs glycosylated to various degrees. The origin of this diversity and its relationship to function led us earlier to compare extensins of the two major

Cells of proso millet (Panicum miliaceum L. cv Abarr) in liquid culture and leaves of maize seedlings (Zea mays L. cv LH51 x LH1131) readily incorporated d-[U-(14)C]glucose and l-[U-(14)C]arabinose into soluble and cell wall polymers. Radioactivity from arabinose accumulated selectively in polymers

Rhizosheaths function in plant-soil interactions and are proposed to form due to a mix of soil particle entanglement in root hairs and the action of adhesive root exudates. The soil-binding factors released into rhizospheres to form rhizosheaths have not been characterised. Analysis of the high

The plant endoplasmic reticulum-Golgi apparatus is the site of synthesis, assembly, and trafficking of all noncellulosic polysaccharides, proteoglycans, and proteins destined for the cell wall. As grass species make cell walls distinct from those of dicots and noncommelinid monocots, it has been
