Freeze-fracture and optical diffraction techniques were used to study the organization of the Euglena pellicle during the normal and replicative stages of the cell cycle and during vitamin B12 starvation. It was shown that the diffuse layer underlyin

A variety of trigger procedures were applied to analyse the exocytotic capability of different Paramecium tetraurelia strains. 7,S K 40I, kin 24I, and 9 (18 degrees C) are capable of exocytosis (permissive strains), in contrast to nd 6, nd 7, nd 9 (2

In Euglena, both nuclear and cellular divisions are stopped by vitamin B12 starvation. In these blocked cells, RNA and protein synthesis continue while the amount of DNA is less than doubled. The cell volume increases five- to tenfold higher than in

A partir d'euglenes vertes synchrones, cultivees soit en heterotrophie sur milieu lactate, soit en phototrophie sur milieu de Cramer et Myers, nous montrons qu'un cycle mitochondrial synchrone avec le cycle cellulaire existe. En phase de division cel

DNA stainability by different fluorochromes has been compared in exponentially dividing and stationary Euglena cells. With the intercalating fluorochromes, ethidium bromide, acridine orange and DAPI, a decrease of fluorescence intensity of the G1 cel

Previous studies on exocytosis in Paramecium using mutants affecting trichocyst extrusion permitted us to analyze the assembly and function of three intramembrane particle arrays ("ring" and "rosette" in the plasma membrane, "annulus" in the trichocy

In different Paramecium tetraurelia strains the occurrence of a Ca2+-ATPase (or p-nitro-phenylphosphatase) activity at the preformed attachment and exocytosis sites of the secretory vesicles (trichocysts) was analysed by electron-microscopic cytochem

Electrophoretic analysis of the envelope of Spinach chloroplasts demonstrated the presence of two polypeptides with apparent molecular weight similar to that of the subunits of the ribulose-1,5-biphosphate-carboxylase (RubPcase). The identification o
