Dictyostelid Cellular Slime Molds from Caves
Dictyostelid cellular slime molds (dictyostelids) are singlecelled, eukaryotic, phagotrophic bacterivores usually present and often abundant in terrestrial ecosystems (Raper, 1984). These organisms represent a normal component of the microflora in soils and apparently play a role in maintaining the natural balance that exists between bacteria and other microorganisms in the soil environment. Fo...
متن کاملDictyostelid Cellular Slime Molds from Hawai'i
Soil and litter samples, collected from Hawai'i on the islands of Hawai'i, O'ahu, and Kaua'i, were examined for occurrence and distribution of dictyostelid cellular slime molds. In total, 194 samples, from 20 different sites and representing several plant communities, were collected during June 1995 and processed in the laboratory soon thereafter. A total of 10 species and one variety was recov...
متن کاملChemoattractant-mediated changes in cytoskeletal actin of cellular slime moulds.
We report changes in actin associated with the Triton-insoluble cytoskeleton following chemotactic stimulation in five species of cellular slime mould, Dictyostelium discoideum, D. mucoroides, D. purpureum, D. lacteum and Polysphondylium violaceum. Stimulation of amoebae with the chemoattractant specific for each species elicits a rapid increase in cytoskeletal actin content with a peak at 5 s,...
متن کاملAre Slime Moulds Living Memristors?
In laboratory experiments we demonstrate that protoplasmic tubes of acellular slime mould Physarum polycephalum show current versus voltage profiles consistent with memristive systems. This result complements previous findings on memristive properties of other living systems (human skin and blood and leaves) and contributes to development of self-growing bioelectronic circuits.
متن کاملCell mixtures of different species and strains of cellular slime moulds.
INTRODUCTION T H E cellular slime moulds have, in their life history, a period of feeding of separate independent amoebae which subsequently stream together (by a process involving chemotaxis) to central collection points. Each of the resulting cell-masses differentiates into a fruiting body; in most species there is a delicate tapering celluose stalk which surrounds the large vacuolate stalk-c...
