Ramie (Boehmeria nivea L. Gaud) is a traditional fiber crop and important medicinal plant belonging to the family Urticaceae. In this study, we determine the complete chloroplast genome sequence of B. nivea. The assembled chloroplast genome is 156065 bp in length and shares the conserved quadripartite structure as other cp genomes in Boehmeria. The genome contains 131 genes, including 84 protein genes, 8 rRNA genes, 37 tRNA genes and 2 pseudo genes. There are 17 duplicated genes in the IR region. The overall GC content of B. nivea is 36.33%, with the highest GC content of 42.72% in IR region. A total of 67 simple sequence repeats are identified in the cp genome of B. nivea. Phylogenetic analysis demonstrated that B. nivea clustered together with B. tomentosa, further forming a monophyletic group with the species of Debregeasia and Pipturus. This work provides basic genetic resources for developing robust markers and investigating the population genetics diversities for B. nivea.
