Incorporation of 3H-Uridine into RNA during Cellular Slime Mould Development

Incorporation of 3H-uridine into RNA during cellular slime mould development.

Pattern of incorporation of (3H)uridine into RNA of amphibian oocyte nucleoli.

Amphibian oocytes were incubated in vitro in the presence of [H]uridine, and autoradiographs were made of nucleoli isolated from these oocytes and of sections of oocytes. After incubations of a h or less the nucleoli of oocytes larger than o-6 mm diameter are asymmetrically labelled. With longer incubations nucleoli from oocytes of o-6 to r i mm diameter become more uniformly labelled. Those of...

Slime mould tactile sensor

Slime mould P. polycephalum is a single cells visible by unaided eye. The cells shows a wide spectrum of intelligent behaviour. By interpreting the behaviour in terms of computation one can make a slime mould based computing device. The Physarum computers are capable to solve a range of tasks of computational geometry, optimisation and logic. Physarum computers designed so far lack of localised...

Slime mould electronic oscillators

We construct electronic oscillator from acellular slime mould Physarum polycephalum. The slime mould oscillator is made of two electrodes connected by a protoplasmic tube of the living slime mould. A protoplasmic tube has an average resistance of 3 MOhm. The tube’s resistance is changing over time due to peristaltic contractile activity of the tube. The resistance of the protoplasmic tube oscil...

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...
