Periodic Reporting for period 1 - EVOBOMICS (Evolution of the interaction between mitochondrial and nuclear genomes in bumblebees (Hymenoptera, Apidae, Bombus): the importance of numts and heteroplasmy)
Berichtszeitraum: 2021-10-04 bis 2023-10-03
Numts are non-functional copies of genes of mitochondrial origin present in the nuclear genome, and heteroplasmy is the presence of different mitochondrial genotypes in the same organism. Although they are completely distinct molecular phenomena, both can be at the same time obstacles and new tools for evolutionary studies. EVOBOMICS aims to investigate numts, heteroplasmy and genomes (nuclear and mitochondrial) at the same time and from an evolutionary perspective. Researchers will identify numts and heteroplasmy in bumblebees to understand their evolution and interaction.

My results indicate that numts and heteroplasmy are common phenomena in bees, both with significant implications for species identification, genetics, and evolution. In the current genomic era, isolating and understanding these phenomena remain major challenges.
When analysing my genomes, I often recover dozens to hundreds of mitochondrial contigs, each displaying unusual characteristics. I believe this diversity of mitochondrial genomes may act as a fail-safe mechanism to retain genetic variation, providing the basis for coadaptation across evolutionary time and space.
Based on my findings, I propose that heteroplasmy plays a key role in species distribution, diversification, and speciation. I am eager to continue advancing this innovative research in the next stages of my work.
