Evolution of New Traits in Microbes

3
Microorganisms evolve rapidly due to their large population sizes and short generation times, often exhibiting measurable changes within days under laboratory conditions. Natural selection acts on standing genetic variation, enabling the retention and amplification of beneficial traits that confer fitness advantages in changing environments.Adaptive Pigment Regulation in RhodobacterIn Rhodobacter, a genus of purple non-sulfur bacteria, light-harvesting pigments such as bacteriochlorophyll and...

Evolution of Microbial Genome

2
Microbial genome evolution is a highly dynamic process shaped by continual gene gain and loss across species and strains. This genomic flexibility allows microorganisms to adapt rapidly to environmental pressures and interactions with other organisms. Central to understanding this diversity is the distinction between the core and pan genomes.The core genome comprises the genes shared by all sampled strains of a species, representing essential functions needed for fundamental cellular processes.

Gene Evolution - Fast or Slow?

8.3K
The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
In contrast, regions which code...

Genome Size and the Evolution of New Genes

9.4K
While every living organism has a genome of some kind (be it RNA, or DNA), there is considerable variation in the sizes of these blueprints. One major factor that impacts genome size is whether the organism is prokaryotic or eukaryotic. In prokaryotes, the genome contains little to no non-coding sequence, such that genes are tightly clustered in groups or operons sequentially along the chromosome. Conversely, the genes in eukaryotes are punctuated by long stretches of non-coding sequence.

Area of Science:

  • Evolutionary biology
  • Developmental biology
  • Genetics

Background:

  • DNA is not the sole determinant of phenotypes.
  • Phenotype construction involves intricate DNA-environment-organism interactions.
  • Understanding these interactions is crucial for evolutionary biology.

Purpose of the Study:

  • To review the process of phenotype construction.
  • To examine interactions between DNA, organism, and environment across evolutionary timescales.
  • To integrate recent findings on phenotypic variation and evolution.

Main Methods:

  • Literature review integrating recent results and examples.
  • Analysis of phenotype construction at individual and population levels.
  • Examination of genetic and environmental influences on variation and inheritance.

Main Results:

  • DNA acts as a template and is involved in feedback loops during phenotype construction.
  • Phenotypic variation arises from joint stochastic, environmental, genetic, and parental sources.
  • Genotype and environment exhibit distinct properties in variation, transmission, and feedback across generations.

Conclusions:

  • Phenotype construction is a dynamic process influenced by multiple interacting factors.
  • Evolutionary processes are shaped by the interplay of DNA, organism, and environment.
  • This review adds depth to the standard evolutionary synthesis by emphasizing these interactions.
