The complete mitochondrial genome sequence of Sua-type cytoplasmic male sterility of tobacco (Nicotiana tabacum)

AbstractTo uncover the cytoplasmic male sterility (CMS)-associated mitochondrial genes of tobacco (Nicotiana tabacum), we determined the complete nucleotide sequence of Sua-CMS mitochondrial genome. The Sua-CMS mtDNA sequence is 522,731 bp in length and contains 34 protein-coding genes, 25 transfer RNA (tRNA) genes, and three ribosomal RNA (rRNA) genes. The nucleotide sequence data of 34 protein-coding genes of 14 mitochondrial genomes were used for constructing the phylogenetic tree. The results showed that Nicotiana tabacum Sua-CMS exhibits most close relationship with other solanaceae species.
