Genetic Drift and Indel Mutation in the Evolution of Yeast Mitochondrial Genome Size
Mitochondrial genomes (mitogenomes) are remarkably diverse in genome size and organization, but the origins of dynamic mitogenome architectures are still poorly understood. For instance, the mutational burden hypothesis postulates that the drastic difference between large plant mitogenomes and streamlined animal mitogenomes can be driven by their different mutation rates. However, inconsistent ...

متن کاملThe selection-mutation-drift theory of synonymous codon usage.
It is argued that the bias in synonymous codon usage observed in unicellular organisms is due to a balance between the forces of selection and mutation in a finite population, with greater bias in highly expressed genes reflecting stronger selection for efficiency of translation. A population genetic model is developed taking into account population size and selective differences between synony...
متن کاملThe mitochondrial genome: mutation, selection and recombination.
Within an individual, mitochondria must function in a range of tissue specific environments that are largely governed by expression of a particular suite of nuclear genes. Furthermore, mitochondrial proteins form large complexes with nuclear-encoded proteins to form the electron-transport system. These dynamics between mitochondrial and nuclear genomes have important implications in studies of ...
متن کاملEvolution of genome size: multilevel selection, mutation bias or dynamical chaos?
In the past two years, new data on conceptual aspects of the evolution of eukaryotic genome size have appeared, including the adaptivity of genome enlargement, the mechanisms of genome size change and the relation of genome size to organismal complexity. New data on the hypotheses of "selfish DNA" and "mutational equilibrium" have been recently obtained. A relationship is emerging between the i...
