Abstract

Cassia siamea is a rosewood species in Southwest China with high wood and medicinal value. To clarify genetic background of C. siamea, we sequenced chloroplast genome by Illumina Hiseq and PacBio Sequel. The whole genome was 148,437 bp in length, containing a large single copy region (77,723 bp), a small single copy region (18,462 bp) and a pair of inverted repeats regions (26,126 bp). The cp genome contained 102 genes (71 protein-coding genes, 27 tRNAs and 4 rRNAs). The phylogenetic analysis indicated that C. siamea is close to Senna tora within Cassiinae/Caesalpiniaceae. The complete chloroplast genome of C. siamea will provide useful resources for the development and utilization of this species and the phylogenetic study of Fabaceae.
