The social amoebae.

نویسنده

  • J T BONNER
چکیده

Noted biologist and author John Tyler Bonner has experimented with cellular slime molds for more than sixty years, and he has done more than anyone else to raise these peculiar collections of amoebae from a minor biological curiosity to a major model organism--one that is widely studied for clues to the development and evolution of all living things. Now, five decades after he published his first pioneering book on cellular slime molds, Bonner steps back from the proliferating and increasingly specialized knowledge about the organism to provide a broad, nontechnical picture of its whole biology, including its evolution, sociobiology, ecology, behavior, and development. The Social Amoebae draws the big lessons from decades of research, and shows how slime molds fit into and illuminate biology as a whole.

بررسی فراوانی آمیب‌های آزادزی در چشمه های آب گرم بهسازی شده استان مازندران در سال 1393

Background: Free-living amoebae, which are called as amphizoic amoebae, could live in various environmental sources such as water, soil, dust and also human and animal tissues. According to possible contamination of hot springs to free living amoebae and developing related disease such as keratitis and encephalitis in people at risk and the lack of knowledge regarding their distribution in hot ...

Genome Analysis of Social Amoebae

Genomics is now an indispensible part of the biological sciences. Today a species description without genome information is incomplete. This chapter describes the current knowledge on the genome of the model species Dictyostelium discoideum. A comparison with other social amoebae genomes covering the whole breadth of this branch of evolution carves out driving forces of speciation and the commo...

Fine-scale spatial ecology drives kin selection relatedness among cooperating amoebae.

Cooperation among microbes is important for traits as diverse as antibiotic resistance, pathogen virulence, and sporulation. The evolutionary stability of cooperation against "cheater" mutants depends critically on the extent to which microbes interact with genetically similar individuals. The causes of this genetic social structure in natural microbial systems, however, are unknown. Here, we s...

An epithelial tissue in Dictyostelium challenges the traditional origin of metazoan multicellularity.

We hypothesize that aspects of animal multicellularity originated before the divergence of metazoans from fungi and social amoebae. Polarized epithelial tissues are a defining feature of metazoans and contribute to the diversity of animal body plans. The recent finding of a polarized epithelium in the non-metazoan social amoeba Dictyostelium discoideum demonstrates that epithelial tissue is not...

The effect of synchronous firing on the clustering dynamics of social amoebae

A discrete model for computer simulations of the clustering dynamics of social amoebae is presented. This model incorporates the wavelike propagation of extracellular signaling of 30–50-cyclic adenosine monophosphate (cAMP), the sporadic firing of cells at early stage of aggregation, the signal relaying as a response to stimulus, and the inertia and purposeful random walk of the cell movement. ...
