Abstract Pyrola atropurpurea Franch is an important annual herbaceous plant. Few genomic analyses have been conducted on this plant, and chloroplast genome research will enrich its genomics basis. This study is based on high-throughput sequencing technology and Bioinformatics methods to obtain the sequence, structure, and other characteristics of the P. atropurpurea chloroplast genome. The result showed that the chloroplast genome of P. atropurpurea has a double-stranded circular structure with a total length of 172,535 bp and a typical four-segment structure. The genome has annotated a total of 132 functional genes, including 43 tRNAs, 8 rRNAs, 76 protein-coding genes, and… More >

Abstract Lonicerae Flos (LF) derived from the dried flower buds or opening flowers of four Lonicera plants (Lonicera macranthoides, L. hypoglauca, L. confusa, and L. fulvotnetosa), is a popular traditional Chinese medicine. Because the four origin plants are very similar in morphology, it is difficult to control the quality of LF in actual production. Over the past decade, many reports have pointed out the differences among them, including the botanical characteristics and active ingredients. However, there is still a lack of rapid methods that can be applied to the identification of the four origins. In this study, comparative analysis of the… More >

Abstract Cerasus Campanulata is one of several species belonging to the Prunoideae focke, a subfamily of the flowering plant Rosaceae. We investigated the details of its chloroplast genome which may reveal its genus independent of morphological determination. Here, we determined the complete chloroplast (cp) genome sequence of C. campanulata and performed sequence analysis to reveal the presence of 18 forward repeats, 20 palindrome repeats, 2 complement repeats, 4 reverse repeats and 93 simple sequence repeats (SSRs). We additionally performed a comparative study of C. campanulata and seven other Prunoideae focke species. Then, maximum parsimony (MP) and maximum likelihood (ML) More >
