The Complete Mitochondrial Genome Sequence Variation and Phylogenetic Analysis of Mulberry

Abstract Mulberry is admired for its landscaping and possesses high development prospects and scientific research value. Mitochondria are the plants' powerhouse that produces energy to carry out life processes. In this study, the mt genome of Morus L(M. atropurpurea and M. multicaulis)were annotated and assembled. The circular mt genome of M. multicaulis has a length of 361,546bp, contains 54 genes, including 31 protein-coding genes, 20 tRNA genes, and 3 rRNA genes and composition of A(27.38%), T (27.20%), C (22.63%) and G (22.79%). The sequence repeats, RNA editing gene and migration from cp to mt and was observed in M. multicaulis mt genome. Phylogenetic analysis based on the complete mt genomes of Morus and other 28 species reflects an exact evolutionary and taxonomic status. Furthermore, we investigation on mt genome size, organization, and plastomes at the global level and pi analysis of Morus genome was investigated and compared to other land plants. The results indicate that the exist mt genome's variation in plants. We reported the mt genome assembly and annotation of a halophytic model plant, M. multicaulis, and subsequent analysis, which provided us with a comprehensive understanding of the Morus mt genome.
