    Comparison between maize root cells and their respective regenerating protoplasts: wall polysaccharides (1984)
    Springer
    Planta 161 (1984), S. 465-469 
    Details
    ISSN: 1432-2048
    Keywords: Cell wall (polysaccharides) ; Polysaccharides (cell wall) ; Protoplast ; Root ; Zea (root, cell wall)
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The cell-wall polysaccharides from different parts of maize roots have been analysed. The arabinose, galactose and mannose contents are influenced by cell differentiation, whereas xylose, rhamnose and uronic-acid contents are not. In cap cells, the pectin content is low but rhamnose and fucose are present in larger quantities. The cell-wall polysaccharides from cells of the elongation zone and their respective regenerating protoplasts were also analysed. The walls of the protoplasts contained higher xylose and mannose levels and a much lower level of cellulose than the cells from which they were derived.

    Zeta potential of protoplasts from gravireacting maize roots (1984)
    Springer
    Planta 162 (1984), S. 17-22 
    Details
    ISSN: 1432-2048
    Keywords: Gravireaction ; Plasmalemma ; Protoplast (zeta potential) ; Root (protoplasts) ; Zea ; Zeta potential (protoplasts, root)
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Protoplasts were isolated from cortical cells of the elongating zone of maize (Zea mays L. cv. LG 11) roots and submitted to microelectrophoresis. Significant and transient differences in zeta potential between protoplasts from upper and lower root sides were compared with the gravireaction and the differential elongation of these roots. The maximum difference in the zeta potential was obtained between protoplasts from the upper and lower cortical cells after 90 min, exactly the time of gravipresentation for which the maximum rate of gravireaction was observed. In addition, this almost corresponded to the time for which the difference between the elongation rates of upper and lower sides of the extending zone began to increase. Consequently, the changes in the charges of the plasmalemma of the cortical cells from the growing part of roots could be more or less directly related to the root graviresponse.

    α-and β-Glycosidases in maize roots (1978)
    Springer
    Planta 138 (1978), S. 119-122 
    Details
    ISSN: 1432-2048
    Keywords: Glycosidases ; Root ; Zea
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Four glycosidases were analyzed in 10 mm apical segments prepared from growing roots (15 mm) of Zea mays L. The pH optima were found to be 5.8 for β-glucosidase, 4.4 for β-galactosidase, 6.4 for α-glucosidase and 6.0 for α-galactosidase. The β-glucosidase showed 4-fold higher activity than the β-galactosidase. The distribution of the β-glucosidase activity was signifcantly different from that of the β-galactosidase, α-glucosidase and α-galactosidase.

    Abscisic acid distribution in horizontal maize root segments (1981)
    Springer
    Planta 153 (1981), S. 453-458 
    Details
    ISSN: 1432-2048
    Keywords: Abscisic acid ; Gravireaction ; Growth inhibitors ; Root ; Zea
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Using gas chromatography-mass spectrometry (GC/MS) techniques of analyses, it has been found that endogenous abscisic acid (ABA) becomes asymmetrically distributed in the elongation zone of horizontal Zea mays (cv. LG 11) roots which are showing a positive gravitropic response. There is a relative increase in the ABA content of the lower half and a concomitant decrease for the upper half in such roots. Asymmetric distribution of ABA is also detected in the elongation zone of half-decapped roots.
