Background:

  • Mitochondrial function is regulated by nuclear gene expression and varies across tissues.
  • Mitochondrial proteins assemble with nuclear-encoded proteins in the electron-transport system.
  • The interplay between nuclear and mitochondrial genomes is crucial for understanding genetic variation and disease.

Purpose of the Study:

  • To investigate the coevolutionary dynamics between nuclear and mitochondrial genomes.
  • To understand how disrupting natural genome combinations impacts biological systems.

Main Methods:

  • Experimental disruption of naturally occurring nuclear and mitochondrial genome combinations.
  • Analysis of resulting genetic variation and phenotypic effects.
