Substructure of Chloroplast Lamellae

(1) Chloroplast lamellae, like many other membranes, are composed of 90-A subunits. (2) The way in which the 90-A units associate with one another determines the quantasome structures of the membrane. There appear to be four 90-A subunits per quantasome in the most highly organized arrays. In at least some cases, the way in which the subunits bind one to another is under environmental control. ...

Photooxidation of Diaminobenzidine (dab) by Chloroplast Lamellae

The introduction of diaminobenzidine (DAB) into ultrastructural cytochemistry in 1966 by Graham and Karnovsky (1) for demonstrating horseradish peroxidase activity was an important milestone. Its usefulness has been extended to demonstration of mitochondrial cytochrome oxidase via cytochrome c by Seligman et al . (2) in 1968, and to demonstration of peroxisomes of kidney (3-5) and peroxisomes o...

Granules Associated with the Chloroplast Lamellae of Porphyridium Cruentum

Small granules with a diameter of approximately 350 A are attached to the chloroplast lamellae of the red alga Porphyridium cruentum. To some extent, their size depends on the culture conditions and the age of the cell. It was possible to preserve the granules only with aldehyde prefixation. It can be seen that fixed or negatively stained granules are comprised of smaller subunits. The granules...

Localization of Chlorophyll in Spinach Chloroplast Lamellae by Fluorescence Microscopy

Chlorophyll in green plants is thought to reside in the internal membranes or lamellae of chloroplasts (1). These membranes are observable by electron microscopy and can be roughly grouped, on the basis of size and arrangement , into grana lamellae and stroma lamellae which exist as closed, flattened sacs, or thylakoids (2). Al though the chlorophyll molecule is not yet demonstrable by electron...
