摘要： Jasmine [Jasminum sambac(L.) Aiton] is an important cultivated plant species that is valued for its ornamental, medicinal and edible values. However, the genomic information available for jasmine is limited. In this study, the complete chloroplast (cp) genomes of single-petal (SP) and double-petal (DP) cultivars of jasmine were investigated. An entire cp genome comparison, inverted repeat contraction and expansion were analyzed among several species, including the two jasmine cultivars, and phylogenetic analysis was performed. The results showed that the complete cp genomes were 163,315 bp (SP) and 163,281 bp (DP) long, respectively. Both genomes exhibited a single circular molecule with quadripartite structure consisting of a pair of inverted repeats separated by the large and small single-copy regions. Both SP and DP cultivars contained 114 unique genes. Sequence analysis identified 31 tandem repeats, 15 forward repeats, 14 palindrome repeats and five complement repeats in both cp genomes. A total of 118 and 117 simple sequence repeats (SSRs) were detected in the cp genomes of SP and DP cultivars, respectively. Phylogenetic analysis strongly supported that the SP cultivar was close to DP, andJ. sambacbelonged to the family Oleaceae, order Contortae. The complete cp genome sequences presented in this report may contribute to genetic and phylogenetic studies of this species.
