A Computational Model of Symbiotic Composition in Evolutionary Transitions [PDF]

open access: yes, 2002
Several of the major transitions in evolutionary history, such as the symbiogenic origin of eukaryotes from prokaryotes, share the feature that existing entities became the components of composite entities at a higher level of organisation.

On the model of symbiotic stars [PDF]

open access: yesInternational Astronomical Union Colloquium, 1982
AbstractWe discuss conditions necessary for appearance and discovery of the symbiotic star phenomenon within the model of a binary consisting of a red (super)giant 3 Mʘ not filling the Roche lobe and of an accreting hot degenerate CO-dwarf 0.8 Mʘ. Within this model “classical” symbiotic stars may exist only within a narrow region of mass accretion ...

Symbiotic stars [PDF]

open access: yesNature, 1981
AbstractI review our current knowledge of symbiotic stars. A great many papers have graced the literature in the fifty years of their study, and many data are available on the spectral variations at optical wavelengths these stars undergo. I do not give extensive references to those data, for previous reviews have done so quite adequately.

A comon genomic framework for a diverse assembly of plasmids in the symbiotic nitrogen fixing bacteria [PDF]

open access: yes, 2008
This work centres on the genomic comparisons of two closely-related nitrogen-fixing symbiotic bacteria, Rhizobium leguminosarum biovar viciae 3841 and Rhizobium etli CFN42.

Symbiotic cardiac pacemaker [PDF]

open access: yesNature Communications, 2019
AbstractSelf-powered implantable medical electronic devices that harvest biomechanical energy from cardiac motion, respiratory movement and blood flow are part of a paradigm shift that is on the horizon. Here, we demonstrate a fully implanted symbiotic pacemaker based on an implantable triboelectric nanogenerator, which achieves energy harvesting and ...

The genetics of symbiotic nitrogen fixation: Comparative genomics of 14 rhizobia strains by resolution of protein clusters [PDF]

open access: yes, 2012
The symbiotic relationship between legumes and nitrogen fixing bacteria is critical for agriculture, as it may have profound impacts on lowering costs for farmers, on land sustainability, on soil quality, and on mitigation of greenhouse gas emissions ...

An improved method for Agrobacterium rhizogenes-mediated transformation of tomato suitable for the study of arbuscular mycorrhizal symbiosis

open access: yesPlant Methods, 2018
Background Solanum lycopersicum, an economically important crop grown worldwide, has been used as a model for the study of arbuscular mycorrhizal (AM) symbiosis in non-legume plants for several years and several cDNA array hybridization studies have ...

A Novel Symbiotic Beverage Based on Sea Buckthorn, Soy Milk and Inulin: Production, Characterization, Probiotic Viability, and Sensory Acceptance

open access: yesMicroorganisms, 2023
Nowadays, vegan consumers demand that food products have more and more properties that contribute to the prevention of some diseases, such as lower fat content, increased mineral content (calcium, iron, magnesium, and phosphorus), pleasant flavor, and ...

Lyophilized Symbiotic Mitigates Mucositis Induced by 5-Fluorouracil

open access: yesFrontiers in Pharmacology, 2021
Mucositis is an adverse effect of cancer chemotherapies using 5-Fluorouracil (5-FU). It is characterized by mucosal inflammation, pain, diarrhea, and weight loss.
