A gene conferring actidione resistance and abnormal morphology on Physarum polycephalum plasmodia - Volume 15 Issue 1 - Jennifer Dee, Russell T. M. Poulter Skip to main content Accessibility help We use cookies to distinguish you from other users … The petri dishes were wrapped in aluminum foil at room temperature (22-25°C) and sealed with parafilm. Using a selfing strain of Physarum polycephalum that forms haploid plasmodia, we have isolated temperature-sensitive growth mutants in two ways. As stated before, pH values at this temperature Complementation in heterokaryons was used to sort the mutants into nine functional groups. 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. AB259870). 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. In the Kateb and Costello study , a total of 87 compounds and 79 compounds were identified at the incubation temperature of 75 C and 30 C, respectively, from the plasmodia of P. polycephalum. Founded in 1807, John Wiley & Sons, Inc. has been a valued source of information and understanding for more than 200 years, helping people around the world meet their needs and fulfill their aspirations. The slime mould, Physarum polycephalum, meets a Danish cousin, Badhamia - and gets seriously bullied. @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. The growth-defective mutants were examined for protein and deoxyribonucleic acid synthesis and for aberrations in mitotic behavior. In the absence of oxygen, no negative Molecular and General Genetics MGG, Vol. The interrelationships of the factors of temperature and pH upon the fruiting of Physarum polycephalum Schw. 1977 Aug;131(2):473-6 J Comput Theore Nanosci 8(3): 383-390.

On the day before the measurement, dried P. polycephalumwas placed on an agarose gel and lightly sprayed with water to induce germination. Generally speaking, the necessity of light for fruiting cannot be dispensed with by increasing acidity nor by lowering the temperature. Maximum temperature at which P. polycephalum will fruit is between 32.5⚬ and 35.0⚬C. -, Cell. -. -, Genet Res.
