The complete chloroplast genome of an irreplaceable dietary and model crop, foxtail millet (Setaria italica)

The complete chloroplast genome sequence of foxtail millet (Setaria italica), an important food and fodder crop in the family Poaceae, is first reported in this study. The genome consists of 1 35 516 bp containing a pair of inverted repeats (IRs) of 21 804 bp separated by a large single copy ([SC) region and a small single-copy (SSC) region of 79 896 bp and 12 012 bp, respectively. Coding sequences constitute 58.8% of the genome harboring 111 unique genes, 71 of which are protein-coding genes, 4 are rRNA genes, and 36 are tRNA genes. Phylogenetic analysis indicated foxtail millet clustered with Panicum virgatum and Echinochloa crus-galli belonging to the tribe Paniceae of the subfamily Panicoideae. This newly determined chloroplast genome will provide valuable information for the future breeding programs of valuable cereal crops in the family Poaceae.
