SUMMARY:Contribution of mitonuclear genomes to evolutionary processes - Fl

DESCRIPTION:Mitochondria play a fundamental role in biology as energy-prod
 ucing organelles with their own DNA (mtDNA)\, which must closely interact 
 and coevolve with the nuclear genome. This talk explores how these mitonuc
 lear interactions drive evolutionary processes\, influencing organismal fi
 tness\, adaptation\, and survival. Focusing on evidence from Drosophila\, 
 we reveal how mtDNA accumulates mutations beneficial to females but detrim
 ental to males\, demonstrating critical evolutionary trade-offs and sex-sp
 ecific selective pressures. Additionally\, we examine how mitonuclear gene
 tic interactions shape nutritional preferences and metabolic adaptations\,
  influencing key life-history traits. These insights extend to understandi
 ng organismal responses to environmental challenges\, such as dietary shif
 ts and temperature fluctuations\, highlighting how mitonuclear compatibili
 ty can buffer or exacerbate physiological stress. Ultimately\, exploring t
 hese complex genetic interactions sheds light on broader evolutionary patt
 erns\, ecological resilience\, and the dynamic interplay between organisms
  and their changing environments.
