[email protected] Abstract OPEN ACCESS Chloroplast genomes are a significant genomic resource in plant species and have been Citation: Wu Z, Gu C, Tembrock LR, Zhang D, Ge S used in many research areas. The complete genomic information from wild crop species (2017) Characterization of the whole chloroplast could supply a valuable genetic reservoir for breeding. Chikusichloa mutica is one of the genome of Chikusichloa mutica and its comparison most important wild distant relatives of cultivated rice. In this study, we sequenced and char- with other rice tribe (Oryzeae) species. PLoS ONE 12(5): e0177553. https://doi.org/10.1371/journal. acterized its complete chloroplast (cp) genome and compared it with other species in the pone.0177553 same tribe. The whole cp genome sequence is 136,603 bp in size and exhibits a typical Editor: Zhong-Jian Liu, The National Orchid quadripartite structure with large and small single-copy regions (LSC, 82,327 bp; SSC, Conservation Center of China; The Orchid 12,598 bp) separated by a pair of 20,839-bp inverted repeats (IRA, B).
