Comparative genomic and phylogenetic analyses of the mitogenome of Graptopetalum Paraguayense (N. E. Br.) Walth. 1938.

ABSTRACT: Graptopetalum paraguayense is a perennial succulent plant with ornamental, ecological, and medicinal value. Here, we present the first complete mitogenome of G. paraguayense, assembled as a circular molecule of 242,059 bp with a GC content of 43.65%. The genome contains 50 genes, including 31 protein-coding genes (PCGs), 13 tRNAs, 3 rRNAs, and 3 pseudogenes. A total of 599 RNA editing sites were identified, with a predominant effect of altering amino acid hydrophobicity (47.41% were hydrophilic-to-hydrophobic conversions). Codon usage bias analysis revealed a preference for GCU (Ala), CGA (Arg), and UUA (Leu), with the stop codon UAA exhibiting the highest RSCU value (1.94). A total of 122 repetitive sequences were identified, comprising 59 simple sequence repeats (SSRs), 1 tandem repeat,
