A genetic system controlling mitochondrial fusion in the slime mould, Physarum polycephalum.
We have identified two distinct mitochondrial phenotypes, namely, Mif+ (mitochondrial fusion) and Mif- (mitochondrial fusion-deficient), and have studied the genetic system that controls mitochondrial fusion in the slime mould, Physarum polycephalum. A mitochondrial plasmid of approximately 16 kbp was identified in all Mif+ plasmodial strains. This plasmid is apparently responsible for promotin...
متن کاملSounds Synthesis with Slime Mould of Physarum Polycephalum
This paper introduces a novel application of bionic engineering: a bionic musical instrument using Physarum polycephalum. Physarum polycephalum is a huge single cell with thousands of nuclei, which behaves like a giant amoeba. During its foraging behavior this plasmodium produces electrical activity corresponding to different physiological states. We developed a method to render sounds from suc...
متن کاملPost-fusion somatic incompatibility in plasmodia of Physarum polycephalum.
High-resolution autoradiography has been used to establish that during the incompatibility reaction that follows fusion between plasmodia of a 'killer' and a 'sensitive' strain of the myxomycete Physarum polycephalum, the nuclei of the sensitive strain are selectively damaged, enclosed in vacuoles and eliminated from the cytoplasm. This damage is visible as increased chromatin condensation and ...
متن کاملPost-fusion Incompatibility in Plasmodia of Physarum Polycephalum
In the myxomycete Physarum polycephalum the somatic incompatibility between plasmodia of a killer strain and a sensitive strain is expressed as a lethal reaction (LR) in the sensitive strain within 6 h after fusion of both plasmodia. The lethal reaction was not caused by any of the extra-cellular compounds produced by the myxomycete nor was the result of intra-cellular compounds of the killer s...
متن کاملThe Changing Pattern of Birefringence in Plasmodia of the Slime Mold, Physarum Polycephalum
Plasmodia of the acellular slime mold, Physarum polycephalum, reveal a complex and changing pattern of birefringence when examined with a sensitive polarizing microscope. Positively birefringent fibrils are found throughout the ectoplasmic region of the plasmodium. In the larger strands they may be oriented parallel to the strand axis, or arranged circularly or spirally along the periphery of e...
