| Popis: | The complete mitogenome of Saccharum spp. hybrid 15a-53 was determined in this study, which contains two distinct circular chromosomes, Chromosome 1 and 2. The length of Chromosome 1 is 300,848 bp with the GC content of 43.93%, while Chromosome 2 is 144,713 bp in length with the GC content of 43.57%. In Chromosome 1, 7.14% of the genome (21,468 nucleotides) is coding DNA and 92.86% (279,380 nucleotides) are intergenic region, while in Chromosome 2, 8.20% of genome (11,865 nucleotides) are coding DNA and 91.80% (132,848 nucleotides) are intergenic region. Chromosome 1 contains 20 protein-coding genes (three atp genes, three ccm genes, two cox genes, one mat gene, one mtt gene, six nad genes, and four rps genes), and 21 non-coding genes (15 tRNA and six rRNAs), while in Chromosome 2, there are 13 protein-coding genes (four nad genes, three rps genes, two atp genes, one ccm gene, one cob gene, one cox gene, and one rpl gene) and five tRNA genes. Maximum Likelihood phylogenetic analysis indicated that 15a-53 is close to S. spp. hybrid ROC22, S. spp. hybrid FN15 and S. officinarum Khon Kaen 3. The complete mitochondrial genome herein will provide useful sequence information for phylogenetic and evolutionary studies for Saccharum and Poaceae. |
