In order to analyze the basic characteristics and phylogeny of the chloroplast genome of Setaria verticillata,in this study the chloroplast genome of Setaria verticillata was sequenced,with the sequencing results assembled,annotated and characteristics analysed.In addition,15 species of grasses with known chloroplast genomes were used to construct phylogenetic trees with Arabidopsis thaliana as exotaxa.The results showed that the total length of chloroplast genome was 138 946 bp,the total GC content was 38.5％,and a total of 131 genes were annotated,including 83 CDS genes,40 tRNA genes and 8 rRNA genes.Codons tend to use codons ending in A/T.60 simple repeat sequences(SSRS)were detected in Setaria verticillata,and A-T repeats were more frequent.Phylogenetic analysis showed that Setaria verticillata was most closely related to Cenchrus echinatus.
