Complementation of Amoebal-Plasmodial Transition Mutants in PHYSARUM POLYCEPHALUM.
Amoebae of the Myxomycete Physarum polycephalum differentiate to yield plasmodia in two ways: in crossing, haploid amoebae of appropriate genotypes fuse to form diploid plasmodia; in selfing, plasmodia form without amoebal fusion or increase in ploidy. Amoebae carrying the mating-type allele matAh (formerly mt(h)) self efficiently, but occasionally give rise to mutants that self at very low fre...
متن کاملViability of Physarum polycephalum spores and ploidy of plasmodial nuclei.
Amoebae of Physarum polycephalum carrying the mth mating-type allele may differentiate into plasmodia in the absence of mating. Such plasmodia are haploid and, upon sporulation, produce mainly inviable spores. We have asked whether the viable spores arise from meiotic or mitotic divisions. Using a microfluorometric measurement of the deoxyribonucleic acid content of individual nuclei, we found ...
متن کاملOn the role of the plasmodial cytoskeleton in facilitating intelligent behavior in slime mold Physarum polycephalum
The plasmodium of slime mold Physarum polycephalum behaves as an amorphous reaction-diffusion computing substrate and is capable of apparently 'intelligent' behavior. But how does intelligence emerge in an acellular organism? Through a range of laboratory experiments, we visualize the plasmodial cytoskeleton-a ubiquitous cellular protein scaffold whose functions are manifold and essential to li...

متن کاملSynchrony in the rhythm of the contraction-relaxation cycle in two plasmodial strands of Physarum polycephalum.
Rhythmicity of contraction of plasmodial strands of Physarum polycephalum was studied, by measuring the isometric tension exerted by isolated segments of the strands. When 2 strands were connected by way of a plasmodial mass, the contraction-relaxation cycle of the 2 strands synchronized. Such cycle activity of the strand was found to be well coordinated with shuttle streaming in the plasmodial...
