| Abstract: | APG IV has a noticeable improvement from the morphological phylogeny which revealed Elaeocarpaceae belonging Oxalidales includes the COM clade with Celastrales and Malpighiales, while the status of COM clade is not well supported based on phylogenetic calculation results of multi-molecular fragments. In order to improve the bootstrap of COM clade, with Sloanea sinensis(genus Sloanea, family Elaeocarpaceae)as materials, we used Illumina Hiseq 2500 platform to sequence, and then assembled, annotated, and analyzed by bioinformatic methods. Analysis of chloroplast genome characteristics was used by MISA and IRscope. The phylogenetic tree of Fabids was reconstructed by using PhyloSuite. The results were as follows:(1)The complete chloroplast genome of Sloanea sinensis was 157 546 bp in length including two inverted repeats(IRs)of 25 984 bp, which were separated by LSC and SSC of 87 904 bp and 17 674 bp, respectively. The GC content was 37.0%.(2)The genome encoded 113 functional genes, including 79 protein-coding genes, 30 tRNA genes, and 4 rRNA genes. 81 SSR loci were detected in the S. sinensis genome, and most of SSR was composed of nucleobase A and T. Through IR expansion and contraction analysis, we found that there were obvious differences between Elaeocarpus japonicus and Sloanea sinensis in LSC/IRB and IRA/LSC boundaries.(3)The whole chloroplast genome phylogenetic studies showed Sloanea sinensis and Elaeocarpus japonicus were sister to Averrhoa carambola, Oxalis corymbosa and O. drummondii. Sloanea sinensis and Elaeocarpus japonicus representing Elaeocarpaceae belonged to Oxalidales, Fabids, and a strongly support for COM clade in Fabids group. Based on the chloroplast genome of genus Sloanea, the phylogenetic status of Elaeocarpaceae and the COM clade is confirmed. |
