Plastome evolution and the plastome phylogeny of the basal asterids.

Plastomes contain rich evolutionary and phylogenetic information. The recent advance of next generation sequencing (NGS) technologies make easy to decoding the whole plastome with a little amounts of materials. In order to resolve outstanding phylogenetic questions on the basal asterids, here we present 10 new plastome sequences by the NGS technologies. All dubious sequence areas were verified by PCR and subsequent Sanger sequencing. The new sequences represented the most of basal asterids including Hydrangeaceae, Cornaceae, Garryaceae, Icacinaceae, Eucommiaceae and Boraginaceae. A monotypic family Eucommiaceae contains several abnormal structural features of plastome compare to the normal plastomes. Three unique major inversions are located on the large single copy (LSC) region of Eucommiaceae plastome. All the three inversions are related to the trn genes. The inverted repeat (IR) regions of Eucommiaceae are expended deep into the small single copy (SSC) region. Furthermore, rps16 genesand two introns of clpP gene are lost in the Eucommiaceae plastome. AccD gene and rpl 23 gene are lost in the Brachybotrys (Boraginaceae) plastome. The phylogenetic distribution patterns of the two genes may help to understand the evolution of Boraginaceae. We also present the results of phylogenetic analyses of the asterids based on the whole plastomes so far fully sequenced.
