Chloroplast genomes are a significant genomic resource in plant species and have been used in many research areas. The complete genomic information from wild crop species could supply a valuable genetic reservoir for breeding. Chikusichloa mutica is one of the most important wild distant relatives of cultivated rice. In this study, we sequenced and characterized its complete chloroplast (cp) genome and compared it with other species in the same tribe. The whole cp genome sequence is 136,603 bp in size and exhibits a typical quadripartite structure with large and small single-copy regions (LSC, 82,327 bp; SSC, 12,598 bp) separated by a pair of 20,839-bp inverted repeats (IR A, B ). A total of 110 unique genes are annotated, including 76 protein-coding genes, 4 ribosomal RNA genes and 30 tRNA genes. The genome structure, gene order, GC content, and other features are similar to those of other angiosperm cp genomes. When comparing the cp genomes between Oryzinae and Zizaniinae subtribes, the main differences were found between the junction regions and distribution of simple sequence repeats (SSRs). In comparing the two Chikusichloa species, the genomes were only 40 bp different in length and 108 polymorphic sites, including 83 single nucleotide substitutions (SNPs) and 25 insertion-deletions (Indels), were found between the whole cp genomes. The complete cp genome of C. mutica will be an important genetic tool for future breeding programs and understanding the evolution of wild rice relatives.

In addition to these species, many wild relatives in the Oryzeae tribe possess enormously useful genetic resources for improving rice breeding through increasing yields [9] and providing tolerance from environmental stress [10].…”

“…It should be noted that Z. latifolia is prevalent throughout China, except in Xinjiang and Tibet, and grows in lakes, ponds, rivers, marshes, and the wetlands [ 6 , 7 ]. It is particularly abundant in the middle and lower Yangtze River basin and Huai River basin [ 5 , 25 , 26 ]. A Z. latifolia survey of 10 lakes of the Eastern China plain over 5 consecutive years revealed growth over a 488-km 2 area, with the generation of ca.…”

“…Z. aquatica and Z. palustris are annual species, whereas Z. texana and Z. latifolia are perennial species [ 3 , 4 ]. The genetic diversity of the North American Zizania species is higher than that of Z. latifolia [ 5 ]. The reasons for the low genetic diversity of the latter include restricted gene flow among populations, self-fertilization as a mode of reproduction, and genetic drift within populations [ 6 ].…”

Zizania latifolia (tribe Oryzeae Dum., subfamily Oryzoideae Care, family Gramineae) is native to East Asian countries. The seeds of Z. latifolia (Chinese wild rice) have been consumed as a cereal in China for >3000 years. Z. latifolia forms swollen culms when infected with Ustilago esculenta, which is the second most-cultivated aquatic vegetable in China. The current review summarizes the nutrients and bioactive compounds of Z. latifolia, and health benefits of its seeds. The seeds of Z. latifolia contain proteins, minerals, vitamins, and bioactive compounds, the activities of which—for example, antioxidant activity—have been characterized. Various health benefits are associated with their consumption, such as alleviation of insulin resistance and lipotoxicity, and protection against cardiovascular disease. Chinese wild rice may be used to prevent and treat metabolic disease, such as diabetes, obesity, and cardiovascular diseases. Various compounds were isolated from the swollen culm, and aerial parts of Z. latifolia. The former suppresses osteoclast formation, inhibits growth of rat glioma cells, and may act as antioxidants and immunomodulators in drugs or foods. The latter exerts anti-fatigue, anti-inflammatory, and anti-allergic effects. Thus, Z. latifolia may be used to produce nutraceuticals and functional foods.

“…Now, in Oryzinae, numerous plastid genomes have been completely sequenced [17,18], however, the finished plastomes from subtribe of Zizaniinae are limited. Zizania is a small genus only comprised of four species including Z. palustris, Z. aquatica, and Z. texana native to North America, and one species Z. latifolia widely distributed in Eastern Asia [19]. As the only species native to Asia, Z. latifolia, named Manchurian wild rice, is used as a food plant with both the stem and grain being consumed in several Asian countries.…”

Plastids, originated from cyanobacteria through endosymbiosis, contain their own DNA genome (plastome), and are uniparentally inherited in most of plant species. In this study, we reported the complete plastome sequence of Manchurian wild rice (Zizania latifolia) obtained by traditional Sanger sequencing and compared it with the previously published plastome of North America wild rice (Z. aquatica) from the same genus. The plastome of Z. latifolia has a total sequence length of 136,461 bp exhibiting a typical circular structure including a pair of 20,878 bp inverted repeats (IRa, b) separated by a large single-copy region (LSC) of 82,115 bp and a small single-copy region (SSC) of 12,590 bp, and it is only 97 bp longer than North America wild rice. The gene content, order, and orientation are similar to all other grass species. Four junctions in two plastome structures are exactly the same between the Zizania species. From complete genome comparisons, 744 (568, 46 and 130 for LSC, IR and SSC) substitutions are found between the two Zizania plastomes including 267 from coding regions and 477 from non-coding regions. Insertions/deletions (Indels) are mainly found in non-coding regions (136) except the only one repeat indel from coding regions in rpoC2 gene. The most informative biomarkers (rps16-trnQ, ndhF and matK) are also the most divergent between the two Zizania species. The completed plastome and comparative analyses from these two Zizania species would be as important resource for further systematic or population genetic studies in the Zizaniinae subtribe, marker assisted breeding, and plastomic transformation.
