Molecular Structure and Phylogenetic Analyses of the Plastomes of Eight Sorbus Sensu Stricto Species.

ABSTRACT: Sorbus L. is a genus of controversy on its taxonomic concept due to great variations in morphological characteristics. Sorbus sensu stricto species, being monophyletic, are characterized as pinnate leaves. However, phylogenetic relationships of these species are somewhat fluid based on morphological characteristics and genetic markers. In this study, the chloroplast (cp) genomes of eight Sorbus s. str. species were characterized and compared with those of twelve released species in this genus. Our results indicated that the plastomes of the twenty Sorbus species had a conserved quadripartite structure, and 129 annotated genes had the same order and showed a good collinearity. Additionally, numerous SSRs were observed in the cp genome of each Sorbus specie
