Analysis of the Genome Structure and Phylogenetic Relationship Between Sarcandra glabra and Sarcandra glabra subsp.brachystachys
The whole chloroplast genomes of Sarcandra glabra and Sarcandra glabra subsp.brachys-tachys were assembled using Illumina whole genome sequencing data,and the total GC content of both was 39％.The total chloroplast genome size of Sarcandra glabra was 158 881 bp,including a large single copy region(LSC)of 88 169 bp,a small single copy region(SSC)of 18 446 bp and a pair of reverse repeat regions(IRs)of 26 133 bp.The total chloroplast genome size of Sarcandra glabra subsp.brachystachys was 158 826 bp,including 88 104 bp LSC,18 440 bp SSC and 26 141 bp IRs.128 genes,including 84 CDS,8 rRNA genes and 36 tRNA genes,were annotated by both plants.Phylo-genetic tree showed that chloroplast genome of Sarcandra glabra was clustered with two Sarcandra glabra genome sequences downloaded by NCBI,and the support rate was 100％,and then the Sar-candra glabra subsp.brachystachys together into a sister group,and the Sarcandra and Chloranthus were sister groups each other.
