Dating Microbial Evolution with MCMCtree
2022This protocol explains how to use the program MCMCtree to estimate divergence times in microbial phylogenies. The main advantage of MCMCtree is the implementation of an approximation to the molecular data likelihood that dramatically speeds up computation during Bayesian MCMC sampling of divergence times and evolutionary rates. The approximation allows

Microbial evolution in laboratory environments
Research in Microbiology, 2004The classical model of evolutionary change in microbial populations is evaluated in terms of recent evidence obtained from genetic and molecular analysis of evolving laboratory populations in simple, defined homogeneous environments. Patterns of change are observed which cannot be predicted from the classical model.

Oxygen toxicity and microbial evolution
Biosystems, 1991It is postulated that the role of oxygen toxicity in the evolution of life strongly depends on the origin of molecular oxygen, due to the strong redox buffering capacity of Precambrian waters containing large amounts of ferrous and manganese cations. The critical selective pressure could be observed only after aerobic photosynthesis had been developed,

The Evolution of Microbial Phosphonate Degradative Pathways
Journal of Molecular Evolution, 2005Phosphonate utilization by microbes provides a potential source of phosphorus for their growth. Homologous genes for both C-P lyase and phosphonatase degradative pathways are distributed in distantly related bacterial species. The phn gene clusters for the C-P lyase pathway show great structural and compositional variation among organisms, but all ...

Darwin and microbial evolution
2010In the 200th year of Charles Darwin’s birth anniversary and 150th year of the publication of the ‘Origin of Species’, biologists are trying to re-evaluate the concept of the evolution as propounded by Darwin in the light of the knowledge gathered through recent developments in genomics and proteomics.

Microbial ecology and evolution
2014Abstract Many ecosystems are wholly microbial and the activities of microorganisms provide the biochemical foundation for plant and animal life. ‘Microbial ecology and evolution’ describes how plants depend upon the complex redox reactions of microbes that fertilize the soil by fixing nitrogen, converting nitrites to nitrates, enhancing ...

Microbial Symbiosis and Evolution
2012This chapter talks about the symbiosis of microbes and mitochondria. Mutations, including deletions of DNA, happen constantly, so the unused genes have long since disappeared from the genomes of mitochondria that inhabit our cells. In fact, mutations are still raining down on the genomes of our mitochondria, and these continue throughout our lives ...
