Abstract Background The Sinodielsia clade of the subfamily Apioideae (Apiacieae) was established in 2008, and it is composed of 37 species from 17 genera. Its circumscription is still poorly delimited and unstable, and interspecific relationships in the clade lack comprehensive analysis. Chloroplast (cp.) genomes provide valuable and informative data sources for evolutionary biology and have been widely used in studies on plant phylogeny. To infer the phylogenetic history of the Sinodielsia clade, we assembled complete cp. genomes of 39 species and then performed phylogenetic analysis based on these cp. genome sequence data combined with 66 published cp. genomes from 16 genera relative to the Sinodielsia clade. Results These 39 newly assembled genomes had a typical quadripartite structure with two inverted repeat regions (IRs: 17,599–31,486 bp) separated by a large single-copy region (LSC: 82,048–94,046 bp) and a small single-copy region (SSC: 16,343–17,917 bp). The phylogenetic analysis showed that 19 species were clustered into the Sinodielsia clade, and they were divided into two subclades. Six mutation hotspot regions were detected from the whole cp. genomes among the Sinodielsia clade, namely, rbc L– acc D, ycf 4– cem A, pet A– psb J, ycf 1– ndh F, ndh F– rpl 32 and ycf 1, and it was found that ndh F– rpl 32 and ycf 1 were highly variable in the 105 sampled cp. genomes. Conclusion The Sinodielsia clade was subdivided into two subclades relevant to geographical distributions, except for cultivated and introduced species. Six mutation hotspot regions, especially ndh F– rpl 32 and ycf 1, could be used as potential DNA markers in the identification and phylogenetic analyses of the Sinodielsia clade and Apioideae. Our study provided new insights into the phylogeny of the Sinodielsia clade and valuable information on cp. genome evolution in Apioideae.
