Complete plastome sequence of Jacaranda mimosifolia D. Don (Bignoniaceae): a beautiful landscaping tree species.

Jacaranda mimosifolia is a deciduous arbor with blue flowers native to Brazil, Bolivia, and Argentina in South America. After introduction from South America, it was widely cultivated as a garden ornamental plant in South China. The complete chloroplast (cp) genome sequence of this ornamental species is reported in this study, based on high-throughput sequencing (Illumina). The complete cp genome is 153,514 bp in length, containing a pair of inverted repeat regions (IRs) of 25,408 bp, a large single-copy (LSC) region of 84,755 bp, and a small single-copy (SSC) region of 17,943 bp. The cp genome contains 130 genes, consisting of 85 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The overall A/T content in the cp genome of J. mimosifolia is 61.70%. The phylogenetic analyses indicate that there is a close relationship between J. mimosifolia and Tecomaria capensis. The complete cp sequence of J. mimosifolia will provide a useful resource for the development and utilization of this species as well as for the phylogenetic studies in Bignoniaceae.

Complete plastome sequence of Elaeagnus glabra (Elaeagnaceae): an Asian endemic plant species.

Elaeagnus glabra is an evergreen vine or climbing shrub with 5 m height. It is widespread in southern China. It grows in the sunny forests or forest margins below 1000 m a.s.l. In this paper, we report and describe the complete plastome of E. glabra in order to provide useful genomic data for its systematic research. The complete plastome of E. glabra is 152,555 bp with a typical quadripartite structure of angiosperms. It contains two Inverted Repeats (IRs) of 25,918 bp, a large single-copy (LSC) of 82,408 bp, and a small single-copy (SSC) region of 18,311 bp. The complete plastome contains 129 genes, including 83 protein-coding genes, 38 tRNA genes, and eight rRNA genes. The overall A/T content in the chloroplast genome of E. glabra is 62.90%. The phylogenetic analysis indicated that E. glabra is close to E. loureirii within Elaeagnaceae. The complete plastome of E. glabra will provide useful resources for the development and utilization of this species and the phylogenetic study of Rosales.
