Soluble Cell Wall Polysaccharides Released from Pea Stems by Centrifugation : I. EFFECT OF AUXIN.
The metabolism of polysaccharides by pea stem segments treated with and without auxin was investigated using a centrifugation technique for removing solution from the free space of the cell wall. Glucose is the predominant sugar in both the ethanol-soluble and ethanol-insoluble fractions of the cell wall solution extracted with water. In the water-soluble, ethanol-insoluble polysaccharides, ara...
متن کاملIdentification of EDTA-Soluble Polysaccharides from Pea Epicotyl Cell Walls and Their Interaction with Xyloglucan
Nascent pectin and glucuronoxylan were prepared from membrane-bound enzymes obtained from pea epicotyls. They had previously been shown to exhibit a proteinand pH-dependent pattern of binding to cell wall ghosts and to xyloglucan extracted from cell walls prepared from pea epicotyls; maximum binding required a pH of 3-4, and the presence of cell wall proteins, namely assemblins. To determine wh...
متن کاملWALL AND SOLUBLE CELL WALL-LIKE POLYSACCHARIDES DERIVED FRO~£ THE SAME AND FROM DIFFERENT PNEUMOCOCCAL STRAINS* BY GERALD SCHIFFMAN,:~ ProD.,
In a previous paper (1), i t was shown tha t strains of pneumococci producing a capsule of soluble polysaccharide (C~) 1 related chemically and immunologically to the C or cell-wall polysaccharide of pneumococcus arise b y spontaneous muta t ion and can be isolated readily from several noncapsulated var iants of this organism. Vaccines of the Cs mutan t s are highly antigenic in rabbits , givin...
متن کاملGlycosylated seryl residues in wall protein of elongating pea stems.
The protein content of salt-washed cell walls isolated from etiolated stems of Pisum sativum L. approximately doubled during elongation. In the same period the concentration in the wall of hydroxyproline, hydrazine-labile (= presumably glycosylated) serine, valine, tyrosine, lysine, and histidine increased markedly in comparison with other amino acids. After elongation was completed both the am...
متن کاملEthylene-induced lateral expansion in etiolated pea stems : kinetics, cell wall synthesis, and osmotic potential.
Treatment of etiolated pea (Pisum sativum L.) internode tissue with ethylene gas inhibits elongation and induces lateral expansion. Precise kinetics of the induction of this altered mode of growth of excised internode segments were recorded using a double laser optical monitoring device. Inhibition of elongation and promotion of lateral expansion began after about 1 hour of treatment and achiev...
