The Complete Chloroplast Genome Sequence of Laportea bulbifera (Sieb. et Zucc.) Wedd. and Comparative Analysis with Its Congeneric Species

( ) is an important medicinal plant of Chinese ethnic minorities, with high economic and medicinal value. However, the medicinal materials of the genus are prone to be misidentified due to the similar morphological characteristics of the original plants. Thus, it is crucial to discover their molecular marker points and to precisely identify these species for their exploitation and conservation. Here, this study reports detailed information on the complete chloroplast (cp) of The result indicates that the cp genome of of 150,005 bp contains 126 genes, among them, 37 tRNA genes and 81 protein-coding genes. The analysis of repetition demonstrated that palindromic repeats are more frequent. In the meantime, 39 SSRs were also identified, the majority of which were mononucleotides Adenine-Thymine (A-T). Furthermore, we compared with eight published plastomes, to explore highly polymorphic molecular markers. The analysis identified four hypervariable regions, including 16, 1, C-GCA and G-GCC. According to the phylogenetic analysis, was most closely related to ( ), and the molecular clock analysis speculated that the species originated from 1.8216 Mya. Overall, this study provides a more comprehensive analysis of the evolution of from the perspective of phylogenetic and intrageneric molecular variation in the genus , which is useful for providing a scientific basis for further identification, taxonomic, and evolutionary studies of the genus.
