The chloroplast genomes of Sanicula (Apiaceae): plastome structure, comparative analyses, and phylogenetic relationships
<p><em>Sanicula</em> (Apiaceae subfamily Saniculoideae) is a taxonomically difficult genus of medicinal value. Its distribution center is in China, where there are 18 species (11 of which are endemic). To provide plastid genome resources, whole chloroplast genomes of five <em>Sanicula</em> species (<em>S. flavovirens</em>, <em>S. giraldii</em>, <em>S. lamelligera</em>, <em>S. odorata</em>, and <em>S. rubriflora</em>) were sequenced and compared to the previously published <em>S. orthacantha</em> plastome. These genomes exhibit a typical quadripartite structure. All contain 129 different genes, including 84 protein-coding, 37 tRNA, and 8 rRNA genes. Loci <em>rpl2</em>, <em>matK</em>, <em>psbA</em>, and <em>ycf1</em> are the most variable. Results of maximum likelihood analysis of 90 whole plastome sequences from Apioideae and Saniculoideae and the outgroup <em>Hydrocotyle</em> (Araliaceae) reveal sectional relationships in <em>Sanicula</em> different from the traditional classification system, support the monophyly of Apioideae and its sister group relationship to Saniculoideae, and show concordant topologies to nrDNA ITS and other plastome-based phylogenies. <em>Sanicula orthacantha</em> and <em>S. chinensis</em> form a clade sister group to <em>S. lamelligera</em> and <em>S. odorata</em>, consecutively. These four species comprise a clade sister group to the clade of <em>S. rubriflora</em> and <em>S. flavovirens</em>, with this entire group sister to <em>S. giraldii</em>. The plastid genome resources provided herein will be important for future systematic, evolutionary, phylogenomic, and population-level studies of <em>Sanicula</em>.</p>
