PMGA: A plant mitochondrial genome annotator

Abstract

Plant mitochondria are essential organelles of plant cells and play crucial roles in oxidative phosphorylation and diverse metabolic processes (Wang et al., 2024). Mitochondria have an endosymbiotic origin, likely from a proteobacterial lineage that branched off before the divergence of known alphaproteobacterial groups (Martijn et al., 2018), and contain their own genetic materials, known as plant mitochondrial genomes (PMGs). PMGs exhibit unique features that may result from mechanisms different from those of nuclei and plastids, such as DNA repair (Chevigny et al., 2020), mRNA splicing (Novikova and Belfort.
