A complete sequence of mitochondrial genome of Neolamarckia cadamba and its use for systematic analysis.

Neolamarckia cadamba is an important tropical and subtropical tree for timber industry in southern China and is also a medicinal plant because of the secondary product cadambine. N. cadamba belongs to Rubiaceae family and its taxonomic relationships with other species are not fully evaluated based on genome sequences.

Comparison of mitochondrial genome and development of specific PCR primers for identifying two scuticociliates, Pseudocohnilembus persalinus and Uronema marinum.

Background: Pseudocohnilembus persalinus and Uronema marinum (Ciliophora, Scuticociliatia), as parasitic scuticociliatid ciliates, were isolated from Scophthalmus maximus and Takifugu rubripes, respectively, in our previous studies. These ciliates are morphologically very similar; hence, it is difficult to identify specific scuticociliate species using traditional classification methods for performing taxonomic research and disease control studies.

Methods: We annotated the mitochondrial genomes of these two scuticociliates on the basis of previous sequencing, including analyses of nucleotide composition, codon usage, Ka/Ks, and p-distance.

Complete chloroplast genome sequence of and comparative analysis with other Zingiberaceae plants.

Objective: (AV) is an herb whose dried fruit has been extensively used in modern medicine to treat digestive system diseases such as dysentery, vomiting and abdominal pain. This paper aims to supplement chloroplast (cp) genomic resources and to be used in phylogenetic studies and identification of AV related plants.

Methods: High-throughput sequencing technology was used to determine the complete sequence of the AV cp genome, and the sequence was then compared with three related species.
