Abstract: To explore the current research progress of mitochondrial genomes of crops, this study concluded the present research status of 12 crop mitochondrial genomes published in NCBI from the aspects of gene composition, molecular structure and so on. Firstly, we summarized the differences of 12 crops in mitochondrial genome size, coding sequence ratio, intron and horizontal gene transfer among chloroplast, mitochondrion and nucleus. Secondly, we analyzed the hot issues of RNA editing, repeat sequence and recombination in the crop mitochondrial genomes. Finally, we discussed the analysis and progress of the association between crop mitochondrial genome and cytoplasmic male sterility (CMS).
