    Notes: [Auszug] KINETIN (6-furfurylaminopurine) is known to delay senescence in detached leaves of certain plant species1-3. Mothes et al. have associated this with another response to kinetin, namely, the accumulation and retention of metabolites in treated areas of leaves, which they have called "kinetin-induced ...

    The greening process in plastids (1965)
    Springer
    Protoplasma 60 (1965), S. 111-130 
    Details
    ISSN: 1615-6102
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Plastids in etiolatedAvena leaves were studied by electron microscopy of thin sectioned material fixed in glutaraldehyde and osmium tetroxide and embedded in Epon. Each plastid contains one—three prolamellar bodies. These are highly ordered systems, the membraneous component of which consists of interconnected tubules lying in the three major axes of a cubic lattice. Where three tubules (one in each axis of the lattice) meet and fuse at the corners of each unit cell, their unit membranes are smoothly confluent so that the principal curvatures of the membrane surface are of opposite sign at every point. A face view of a unit cell shows four tubules delimiting a circular opening of diameter 380 Å. The diameter of the tubules is 210 Å at their narrowest point, i. e. half way along the edges of the unit cells. The plastid stroma penetrates the prolamellar body via the 380 Å openings, and contributes ribosome—like particles to the system. These particles are centrally located, one in each unit cell. The literature on prolamellar bodies is reviewed, it is concluded that this type of organisation is widespread in plants. Structures with similar geometry are described, and it is suggested that the unit membranes of the lattice are laid down on contours of uniform “field” strength centred on the lattice of ribosome-like particles. The surface area of membrane in a prolamellar body is estimated.

    An ultrastructural and cytochemical study of the wall-membrane apparatus of transfer cells using freeze-substitution (1977)
    Springer
    Protoplasma 93 (1977), S. 7-26 
    Details
    ISSN: 1615-6102
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary A freeze-substitution technique is described which enables the ultrastructure of certain types of plant transfer cells to be preserved with minimal ice crystal damage. The ultrastructure of transfer cells fromFunaria, Lonicera, andSenecio after freeze-substitution has been compared with that of glutaraldehyde-osmium fixed material. The irregular clear zone between wall and plasma membrane, present in conventional preparations, is absent in freeze-substituted tissue. It is proposed that this interfacial zone is an artefact caused by expansion of wall ingrowth material during conventional fixation procedures. In transfer cells with a complex wall labyrinth the swelling of wall material severely disrupts the true structure of the wall-membrane apparatus and results in a large decrease in the surface to volume ratio of the protoplast. These findings are supported in the case ofFunaria by a freezefracture study. The reactivity of the plasma-membrane to the PTA/chromic acid stain is enhanced in freeze-substituted material. Use of theThiéry silver proteinate reagent in conjunction with freeze-substitution has revealed marked differences between the wall ingrowths ofFunaria sporophyte haustorium transfer cells and those ofLonicera nectary trichomes.
