January 16, 2021

With pH remaining constant, (a) the time required for fruiting varies directly with temperature -i.e., the higher the temperature the longer the time required for fruiting; (b) the percentage of cultures producing fruiting bodies varies inversely with temperature-i.e., the higher the temperature, the smaller the percentage fruiting.

Tanaka Y, Nakagaki T (2011) Cellular computation realizing intelligence of slime mold Physarum Polycephalum. Since Howard stated that the optimum temperature for P. polycephalum is between 20.00 and 26.0?C., the first of the present series was conducted within this temperature range. Execution of this step is necessary for both mitosis and chromosome replication. ©2000-2021 ITHAKA. 1977 Dec;12(4):1109-20 The physarum polycephalum in form of sklerotia was cultivated in petri dishes covered with 1,5 and 2% agar-agar and pour with some drops of water.

Changes in the membrane and zeta potentials, which were induced by chemical stimuli, decreased when the temperature decreased below T c . The latter shows a striking reduction in the frequency of postmitotic reconstruction nuclei at the restrictive temperature. Under the conditions of the above experiments, sclerotia cannot be produced at high temperatures (32.5⚬-35.0⚬) nor at low temperatures (8⚬-12⚬). 1, p. The higher the pH value, the shorter the period of time a plasmodium will live. Complementation in heterokaryons was used to sort the mutants into nine functional groups. The “acellular” moniker derives from the plasmodial stage of the life cycle: the plasmodium is a bright yellow macroscopic multinucleate coenocyte shaped in a network of interlaced tubes. @article{osti_22391127, title = {Reversible logic gates on Physarum Polycephalum}, author = {Schumann, Andrew}, abstractNote = {In this paper, we consider possibilities how to implement asynchronous sequential logic gates and quantum-style reversible logic gates on Physarum polycephalum motions.
