Substructure of Flagellar Tubules
The 9 + 2 array of ciliary and fiagellar tubules was described in the early days of electron micros-copy when osmium tetroxide was the standard fixative. Cytoplasmic microtubules, which are not generally in evidence after osmium tetroxide fixation, were rarely seen until after the advent of aldehyde fixatives. In some glutaraldehyde-OsO4-fixed material, flagellar and ciliary tubules are
متن کاملObservations on the substructure of flagellar fibres.
The substructure of the outer and central fibres of the flagella of Trichonympha and other flagellates has been examined by electron microscopy, using negatively-stained material. Periodicities revealed in the micrographs have been analysed by studying the optical diffraction patterns obtained from them. Outer and central fibres appear to be essentially similar in substructure and are made up o...
متن کاملFLAGELLAR MUTANTS LACKING RADIAL SPOKES AND CENTRAL TUBULES Structure, Composition, and Function of Specific Axonemal Components
The fine structure, protein composition, and roles in flagellar movement of specific axonemal components were studied in wild-type Chlamydomonas and paralyzed mutants pf-14, pf-15A, and p f-19. Electron microscope examination of the isolated axoneme of pf-14 showed that it lacks the radial spokes but is otherwise structurally normal. Comparison of isolated axonemes of wild type and pf-14 by sod...

متن کاملSubstructure 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. ...
