Abstract
Complete chloroplast (cp) genomes were reconstructed for seven Manglietia (Ma. aromatica, Ma. calcarea, Ma. conifera, Ma. duclouxii, Ma. glaucifolia, Ma. insignis and Ma. megaphylla) and one Michelia (Mi. alba) species using Illumina sequencing technology, with their genome sizes ranging from 159,973 to 160,106 bp. They all comprise a pair of inverted repeat (IR) regions, which were separated by a large single-copy (LSC) region and a small single-copy (SSC) region, and encode the same set of 132 genes, including 87 protein-coding genes (79 PCG species), 37 tRNA genes (30 tRNA species) and eight rRNA genes (four rRNA species). Sixteen gene species contain one or two introns. These cp genomes have almost identical A + T-biased nucleotide compositions. Phylogenetic analysis supported the current subfamily-level taxonomy of the family Magnoliaceae, but challenged the genus-level taxonomy of the subfamily Magnolioideae.
