Characteristics of the Complete Plastid Genome Sequences of the Monotypic Genus Dodecadenia (Family: Lauraceae) and Its Phylogenomic Implications

As one of a dozen monotypic genera in the family Lauraceae, systematic position Dodecadenia Nees remains controversial. Here, two complete plastomes grandiflora were sequenced. The plastid genomes, with length 152,659 bp and 152,773 bp, had similar quadripartite structure. Both consisted large single-copy (LSC) region 93,740 93,791 small (SSC) 18,805 18,846 pair inverted repeats (IR) regions 20,057 20,068 bp. A total 128 genes annotated for D. genomes (plastomes), which included 84 protein-coding (PCGs), 36 tRNA eight rRNA genes. Codon usage analysis showed bias toward A/U at third codon. 122 RNA editing events predicted, all codon conversions cytosine to thymine. There 30/36 oligonucleotide 89/94 simple sequence these grandiflora. Based on 71 plastomes, both Bayesian maximum likelihood phylogenetic analyses that are nested among species Litsea Lam. together auriculata Chien et Cheng suggested genus should be revised. In addition, highly variable loci trnG intron ycf3-trnS could used as excellent candidate markers population genetic
