Comparison of the complete genomes of two Echinochloa species: barnyard grass and jungle rice

Abstract

We sequenced and compared the complete chloroplast (cp) genomes of the two Echinochloa species; E. crus-galli (KT983256) and E. colona (KT983255). The size of complete chloroplast genomes of the two species are 139,851 and 139,592 base pairs in length, respectively. They include a pair of inverted repeats (22,640 and 22,618 bp) separated by the small (12,518 and 12,519 bp) and large (82,053 and 81,837 bp) single copy regions. Both chloroplast genomes include a total of 136 genes. Phylogenetic analysis revealed that E. colona was diverged between 2.65 and 3.18 million years ago (Mya) from the E. oryzicola and E. crus-galli.
