The complete mitochondrial genome of upland rice (Oryza sativa) in southwest of China

Abstract

We sequenced complete mitochondrial genome of upland rice Oryza sativa (Liliopsida: Poales: Poaceae) with length of 444,883 bp. The genome has similar codon usage and gene organization to those of mitogenome reported for other Poales. It includes 55 protein-coding genes, 6 ribosomal RNA genes, and 26 transfer RNA genes. The overall base composition is A (27.94%), T (28.46%), G (21.86%), C (21.74%), so the relatively balanced base content was detected. Phylogenetic analyses showed that O. sativa is closely related to Oryza rufipogon that is also a member of the same genus, which is a widely accepted view.
