论文摘要：
Sophora japonica var. violacea is an important ornamental plant, but its wild populations are now in danger, and need urgent conservation. In the present study, we sequenced the complete chloroplast genome of S. japonica var. violacea and used these data to assess genomic resources. The S. japonica var. violacea chloroplast genome is 158,837 bp in length, and includes a pair
of inverted repeats of 25,398 bp that are separated by small and large single copy regions of 19,058 and 88,983 bp, respectively. The chloroplast genome of S. japonica var. violacea encodes 112 different genes, including 78 protein-coding genes, 30 transfer RNAs (tRNA) and 4 ribosomal RNAs (rRNA). We identified a total of 171 simple sequence repeat markers in the chloroplast genome. A phylogenetic tree constructed based on 78 protein-coding genes of 42 angiosperms showed that the position of S. japonica var. violacea is on the base of Papilionoideae. Overall, the results of this study will contribute to better support of the evolution, molecular biology and genetic improvement of S. japonica var. violacea.
