1. CARACTERÍSTICAS TECNOLÓGICAS DO VERGAMENTO DAS MADEIRAS DE Luehea divaricata, Carya illinoinensis E Platanus x acerifolia COMO SUBSÍDIOS PARA O MANEJO FLORESTAL. / TECHNOLOGICAL CHARACTERISTICS OF BENDING OF THE WOOD OF Luehea divaricata, Carya illinoinensis AND Platanus x acerifolia AS SUBSIDIES FOR THE FOREST HANDLING.
O presente trabalho foi desenvolvido com o objetivo de investigar as características do vergamento da madeira de plátano (Platanus x acerifolia), açoita-cavalo (Luehea divaricata) e nogueira-pecã (Carya illinoinensis) procedentes de florestas não-manejadas para este fim das regiões da Depressão Central e Encosta Superior do Nordeste do estado do Rio G

2. The Structure of Plant Cell Walls: II. The Hemicellulose of the Walls of Suspension-cultured Sycamore Cells 1
The molecular structure, chemical properties, and biological function of the xyloglucan polysaccharide isolated from cell walls of suspension-cultured sycamore (Acer pseudoplatanus) cells are described. The sycamore wall xyloglucan is compared to the extracellular xyloglucan secreted by suspension-cultured sycamore cells into their culture medium and is also

3. Generation of monoclonal antibodies against plant cell-wall polysaccharides. I. Characterization of a monoclonal antibody to a terminal alpha-(1-->2)-linked fucosyl-containing epitope.
Monoclonal antibodies (McAbs) generated against rhamnogalacturonan I (RG-I) purified from suspension-cultured sycamore maple (Acer pseudoplatanus) cells fall into three recognition groups. Four McAbs (group I) recognize an epitope that appears to be immunodominant and is present on RG-I from maize and sycamore maple, pectin and polygalacturonic acid from cit

4. Structure of Plant Cell Walls 1: XXVI. The Walls of Suspension-Cultured Sycamore Cells Contain a Family of Rhamnogalacturonan-I-Like Pectic Polysaccharides
Considerable information has been obtained about the primary structures of suspension-cultured sycamore (Acer pseudoplatanus) cell-wall pectic polysaccharides, i.e. rhamnogalacturonan I, rhamnogalacturonan II, and homogalacturonan. However, these polysaccharides, which are solubilized from the walls by endo-α-1,4-polygalacturonase, account for only about ha

5. The Structure of Plant Cell Walls: IV. A Structural Comparison of the Wall Hemicellulose of Cell Suspension Cultures of Sycamore (Acer PseudoPlatAnus) and of Red Kidney Bean (Phaseolus Vulgaris) 1
The molecular structure and chemical properties of the hemicellulose present in the isolated cell walls of suspension cultures of sycamore (Acer pseudoplatanus) cells has recently been described by Bauer et al. (Plant Physiol. 51: 174-187). The hemicellulose of the sycamore primary cell wall is a xyloglucan. This polymer functions as an important cross-link

6. The Structure of Plant Cell Walls: I. The Macromolecular Components of the Walls of Suspension-cultured Sycamore Cells with a Detailed Analysis of the Pectic Polysaccharides 1
This is the first in a series of papers dealing with the structure of cell walls isolated from suspension-cultured sycamore cells (Acer pseudoplatanus). These studies have been made possible by the availability of purified hydrolytic enzymes and by recent improvements in the techniques of methylation analysis. These techniques have permitted us to identify a

7. Preparation and Characterization of Envelope Membranes from Nongreen Plastids
We have developed a reliable procedure for the purification of envelope membranes from cauliflower (Brassica oleracea L.) bud plastids and sycamore (Acer pseudoplatanus L.) cell amyloplasts. After disruption of purified intact plastids, separation of envelope membranes was achieved by centrifugation on a linear sucrose gradient. A membrane fraction, having a

8. Transport, Compartmentation, and Metabolism of Homoserine in Higher Plant Cells : Carbon-13- and Phosphorus-31-Nuclear Magnetic Resonance Studies
The transport, compartmentation, and metabolism of homoserine was characterized in two strains of meristematic higher plant cells, the dicotyledonous sycamore (Acer pseudoplatanus) and the monocotyledonous weed Echinochloa colonum. Homoserine is an intermediate in the synthesis of the aspartate-derived amino acids methionine, threonine (Thr), and isole

9. A Sycamore Cell Wall Polysaccharide and a Chemically Related Tomato Leaf Polysaccharide Possess Similar Proteinase Inhibitor-Inducing Activities 1
A large pectic polysaccharide, called rhamnogalacturonan I, that is solubilized by a fungal endo-α-1,4-polygalacturonase from the purified walls of suspension-cultured sycamore cells possesses proteinase inhibitor-inducing activity similar to that of the proteinase inhibitor-inducing factor, a pectic-like oligosaccharide fraction isolated from tomato leaves

10. Immunochemical Analysis Shows That an ATP/ADP-Translocator Is Associated with the Inner-Envelope Membranes of Amyloplasts from Acer pseudoplatanus L. 1
Pure preparations of intact amyloplasts and chloroplasts, free from mitochondrial contamination, were isolated from cultured cells of the white-wild and green-mutant lines of sycamore (Acer pseudoplatanus L.), respectively. A specific rabbit antiserum against yeast mitochondrial cytochrome c1 only cross-reacted with mitochondrial membranes from the white-wil

11. Survival of Suspension-cultured Sycamore Cells Cooled to the Temperature of Liquid Nitrogen 1
Suspension-cultured cells of sycamore (Acer pseudoplatanus L.) which were immersed in liquid nitrogen after prefreezing to the temperatures from −30 to −50 C in the presence of dimethylsulfoxide and glucose as cryoprotective additive could proliferate vigorously when rewarmed rapidly in water at 40 C. For maintaining high viability of the cells after imm

12. Characterization of a Cytosolic Aconitase in Higher Plant Cells
Protoplasts obtained from sycamore (Acer pseudoplatanus) cell suspensions were found to be highly intact. If the protoplasts were taken up and expelled through a fine nylon mesh, all the protoplasts were ruptured leaving the fragile amyloplasts largely intact. Aconitase hydratase (citrate [isocitrate] hydro-lyase, EC 4.2.1.3) activity of sycamore cells was a
