The complete chloroplast genome of Mimosa pigra L. (Fabaceae), a notorious invasive plant

Abstract

Mimosa pigra L., also called the giant sensitive tree, is native to tropical America and has invaded Africa, Asia, and Australia. Here, we report the complete chloroplast genome of M. pigra, which was 165,996 bp in length and composed of a large single-copy region (LSC; 93,299 bp), a small single-copy region (SSC; 17,989 bp) and two inverted repeat regions (IRs; 27,354 bp). The complete M. pigra chloroplast genome included 83 protein-coding genes, 37 tRNAs and 8 rRNAs. Phylogenetic analysis using the maximum likelihood method revealed the monophyly of M. pigra and related taxa of the subfamily Caesalpinioideae. In comparison, the members of Papilionoideae were paraphyletic.
