Temperature-sensitive mutants of the slime mould Physarum polycephalum. Using a selfing strain of Physarum polycephalum that forms haploid plasmodia, we have isolated temperature-sensitive growth mutants in … Isolation of cell cycle mutants of Physarum polycephalum. Action spectrum was determined, which accords well with action spectrum for generation of super oxide anion. 1977 Aug;131(2):473-6 Naturwissenschaften. This site needs JavaScript to work properly. Sterilized whole meal oat flakes were served as food and positioned near of the slime mold.

Using a selfing strain of Physarum polycephalum that forms haploid plasmodia, we have isolated temperature-sensitive growth mutants in two ways. Action spectrum for sporulation and photoavoidance in the plasmodium of Physarum polycephalum, as modified differentially by temperature and starvation. The latter shows a striking reduction in the frequency of postmitotic reconstruction nuclei at the restrictive temperature. In the temperature range around 10–30 °C, the plasmodium shows thermotaxis to the higher temperature. Would you like email updates of new search results? Mol Gen Genet. Phototaxis in Physarum polycephalum 271 A tungsten 8V-30W microscope lamp (Olympus Co., Tokyo) was used to observe proto-plasmic … One mutant may be defective in both protein and deoxyribonucleic acid synthesis, and another only in deoxyribonucleic acid synthesis. Cycloheximide resistance of Physarum polycephalum. The thermotaxis of the plasmodium is so strong and the organism without learning always proceeds to the higher temperature region. The P. polycephalumcultured on the gel vividly about 12 hours later. Physarum Polycephalum changes polyaniline properties Alice Dimonte 1, Tatiana Berzina 1 and Victor Erokhin 1 1 CNR-IMEM (National Council of the Researches ± Institute of Materials for Electronics and Magnetism), Parco Area delle 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. When transferred to the restrictive temperature, two mutants immediately lysed, whereas the remainder slowed or stopped growing. Published by the Botanical Society of America continuously since 1914, the American Journal of Botany (AJB) is the Society’s flagship research journal. This stage of the life cycle, along with its preference for damp shady habitats, likely contributed to the original mischaracterization of the organism as a fungus.  |  USA.gov. Action Spectrum for Sporulation and Photoavoidance in the Plasmodium of Physarum polycephalum, as Modified Differentially by Temperature and Starvation Toshiyuki Nakagaki Corresponding Author The slime mould, Physarum polycephalum, meets a Danish cousin, Badhamia - and gets seriously bullied. JSTOR is part of ITHAKA, a not-for-profit organization helping the academic community use digital technologies to preserve the scholarly record and to advance research and teaching in sustainable ways.

Poulter Skip to main content Accessibility help We use cookies to distinguish you from other users … 163, Issue. 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.
