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

Abstract 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 evaluate...
