The complete chloroplast genome sequence of Japanese Millet Echinochloa esculenta (A. braun) H. scholz (Poaceae)

Abstract

Japanese Millet, Echinochloa esculenta is a weed-suppressing cover crop that was grown once as a staple food crop in Japanese regions when rice cultivation failed. Here, we report the complete chloroplast (cp) genome sequence of E. esculenta for the first time to understand the diversification of this species in the family Poaceae. The size of the circular chloroplast genome is 139,851 bp in length with 38.6% overall GC content which exhibits a typical quadripartite structure, containing pair of inverted repeats of 22,748 bp, flanked by large single copy and small single copy regions of 81,837 bp and 12,518 bp, respectively. The cp genome encodes 111 unique genes, 76 of which are protein-coding genes, four rRNA genes, 30 tRNA genes, and 18 duplicated genes in the inverted repeat region. The phylogenetic analysis indicated that the E. esculenta is closely related with the wild relative barnyard grass (E. crus-galli).
