Interpretive Summary: In sorghum and other cereal species, there is an impending need for a clear understanding of the organization of the nuclear genome, but also the other genomes that reside in mitochondria and chloroplasts. To this end, we have sequenced DNA and assembled the genomes of mitochondria and chloroplasts from a large number of sorghums to better understand the evolution of these unique genomes. These assembled genomes represent tools to better understand the functioning of these organelles that are the seat of respiration and photosynthesis within all plant species.

Technical Abstract: Mitochondria are organelles within eukaryotic cells that are central to the metabolic processes of cellular respiration and ATP production. However, the evolution of mitochondrial genomes (mitogenomes) in plants is virtually unknown compared to animal mitogenomes or plant plastids, due to complex structural variation and long stretches of repetitive DNA making accurate genome assembly more challenging. Comparing the structural and sequence differences of organellar genomes within and between sorghum species is an essential step in understanding evolutionary processes such as organellar sequence transfer to the nuclear genome as well as improving agronomic traits in sorghum related to cellular metabolism.
