Viability 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 کاملValine requirement of nursery pigs.
Six experiments were conducted to determine the true digestible valine requirement of 5- to 20-kg pigs. In Exp. 1, a valine-deficient diet for 5- to 10-kg pigs was developed and validated in terms of growth performance in response to supplemental L-valine. A different basal diet was validated for 10- to 20-kg pigs in Exp. 2. Both diets were demonstrated to be deficient in valine and to support ...
متن کاملComplementation 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 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 کاملEvaluation of Physarum polycephalum plasmodial growth and lipid production using rice bran as a carbon source
BACKGROUND The myxomycete Physarum polycephalum appears to have remarkable potential as a lipid source for biodiesel production. The present study evaluated the use of rice bran as a carbon source and determined the medium components for optimum growth and lipid production for this organism. RESULTS Optimization of medium components by response surface methodology showed that rice bran and ye...
