Abstract
Vetiver grass (Chrysopogon zizanioides), is a perennial and tussock C4 grass from the genus Chrysopogon of Poaceae, which has been widely used as a natural and inexpensive resource for multifarious environmental applications. The complete mitogenome of C. zizanioides was 551,622 bp in length, containing 40 protein-coding genes (PCGs), 19 transfer RNA genes (tRNAs), and six ribosomal RNA genes (rRNAs). All PCGs started with ATG and stopped with TNN (TAA, TAG, and TGA). The overall nucleotide composition is: 28.2% A, 28.2% T, 21.7% G, and 21.9% C, with a biased A + T content of 56.4%. Phylogenetic analysis using 14 PCGs of 22 species showed that C. zizanioides display a close relationship with Saccharum officinarum (LC107874) and Sorghum bicolor (DQ984518) in Poaceae.
