Effect of growth conditions on development of the cellular slime mould, Dictyostelium discoideum.
The effect of growth in the presence and absence of 86 m\i glucose on fruiting-body number and size, fruiting-body proportions and morphogenesis in the slime mould Dictyostelium discoideum, strain Ax-2, has been investigated. Cells grown in the absence of glucose (N.S. cells) formed 2-1 limes more fruiting bodies than glucose-grown cells allowed to differentiate under the same conditions and at...
متن کاملControl of cellular differentiation by temperature in the cellular slime mould Dictyostelium discoideum.
The effects of low temperature on morphogenesis and cellular differentiation of Dictyostelium discoideum were examined. During incubation at 5 degrees C, the vegetative and preaggregation cells never developed, but cell masses at the aggregation or slug stage developed to form hemispherical, or dumbbell-shaped multicellular structures. By staining with FITC-antispore IgG, the structures formed ...
متن کاملA genetic study of aggregation in the cellular slime mould Dictyostelium discoideum using complementation analysis.
A series of aggregation-deficient (aggregateless) mutants were isolated in genetically marked haploid strains of the cellular slime mould Dictyostelium discoideum. Diploids were produced from pairs of such haploid mutants by a fusion system based on this organism's parasexual cycle. The diploids were isolated from the haploids by using complementation of non-allelic growth-temperature-sensitive...
متن کاملA bacterial factor induces changes in cysteine proteinase forms in the cellular slime mould Dictyostelium discoideum.
The electrophoretic pattern of cysteine proteinases in axenically grown myxamoebae of Dictyostelium discoideum can be altered by the addition of either Gram-negative (Klebsiella aerogenes, Escherichia coli) or Gram-positive (Micrococcus lysodeikticus, Bacillus subtilis) bacteria to the culture. No changes occurred, however, if either yeast or latex beads were used in place of bacteria. The chan...
متن کاملGrowth of myxameobae of the cellular slime mould Dictyostelium discoideum in axenic culture.
1. A simple axenic medium suitable for the growth of the myxamoebae of a strain of the cellular slime mould Dictyostelium discoideum is described. 2. Procedures suitable for the growth of this strain in liquid and on solid media are described. 3. Conditions suitable for initiating the cell differentiation of myxamoebae grown axenically are described.
