The whole chloroplast genome of Sphaerophysa salsula was sequenced and assembled based on Illumina high-throughput sequencing platform. The assembly result indicated that the whole chloroplast genome of S. salsula had a total length of 123 327 bp, with a loss of IR region. The chloroplast genome encoded a total of 108 genes, including 74 protein-coding genes, 4 rRNA genes and 30 tRNA genes. and 99 SSR loci were found, and among them the number of mononucleotide, dinucleotide and trinucleotide repeat motifs was 75, 17 and 7, respectively. The phylogenetic analysis results showed that S. salsula and Alhagi sparsifolia were sister species, which had the closest genetic relationship. The results would lay the foundation for the genetic diversity, population genetic structure and speciation mechanism of S. salsula in the future.

Key words: Sphaerophysa salsula, chloroplast genome, simple sequence repeats, codon preference, phylogeny
