“…latifolia Turcz., which belongs to the tribe Oryzeae within Gramineae, is a perennial aquatic plant grown in lakes, pond, or wetlands, and it is cultivated mainly in regions of southeastern Asia, including Russia, Korea, Japan, and China. 28) In China, culms and rhizomes are used as a tonic to treat anemia and fever in addition to heart, kidney, and liver disorders. 29) Although various reports have been carried out on the nutritional aspects of the grain, little attention has been given to the biological efficacy of the aerial part of this plant.…”

Methanol extract of Zizania latifolia was partitioned with EtOAc, n-BuOH, and H2O. From the EtOAc layers, a new flavonolignan along with a known flavone and three known flavonolignans, tricin (1), salcolin A (2), salcolin B (3), and salcolin C (4), were isolated through repeated silica gel and ODS column chromatography. The chemical structure of the new flavonolignan was determined to be tricin-4′-O-[erythro-β-guaiacyl-(7″-O-methyl)-glyceryl] ether and was named salcolin D (5) based on physicochemical and spectroscopic data, including FT-NMR and ESI-MS. All compounds were isolated for the first time from this plant. Compounds 2–5, tricin derivatives, all exhibited higher anti-inflammatory and anti-allergy activities than tricin. In particular, salcolin D (5) was shown to have the strongest inhibitory activity against LPS-induced NO production in RAW 264.7 cells as well as β-hexosaminidase release in IgE-sensitized RBL-2H3 cells. These results suggest that the presence of tricin derivatives conveys allergy and inflammation treatment ability to Z. latifolia.

“…Z. latifolia is a pioneer weed species for dyke consolidation because of its high clonal reproduction; it also has a high nutrient uptake capacity which is used to purify wastewater. Its seeds or young shoots are popular foods or vegetables in China (Guo et al, 2007). Moreover, some eminent traits in Z. latifolia are used for rice breeding owing to its close relationship to rice (Oryza sativa L.) (Chen Y. et al, 2006).…”

Landscape-Scale Genetic Structure of Wild Rice Zizania latifolia: The Roles of Rivers, Mountains and Fragmentation

et al. 2017

Wild rice (Zizania latifolia) is an important genetic resource and it has important ecological functions in aquatic ecosystems as well. Here, we used landscape genetics to investigate how the landscape features, including rivers, mountains and habitat fragmentation, affect the genetic connectivity or create dispersal barriers for Z. latifolia. In this report, seventeen populations from the Sanjiang Plain and its surrounding areas were genotyped by ten microsatellite markers. A high genetic differentiation and genetic discontinuity were found among populations within each river investigated, suggesting that the rivers be not acting as corridors for dispersal. Meanwhile, genetic discontinuity was detected from different sides of the Lesser Khingan and its branch, the Qinghei Mountains, demonstrating that gene flow was blocked by the complex topography of mountains. The results that historical gene flow was much higher than the contemporary gene flow might infer that recent habitat fragmentation resulted in decreased gene flow. For all sampled Z. latifolia populations, the result of low level of genetic variation (n a = 2.3, H E = 0.328) and high genetic divergence (F ST = 0.405, D est = 0.414 and Ø pt = 0.424) was consistent with the decreased gene flow, an inbreeding system and repeated genetic bottlenecks. A conservation strategy for protecting as many populations as possible to maximize genomic representation of the species is proposed. In addition, dredging the watercourses should be carried out to improve habitat stability and to facilitate connectivity among populations.

“…Both Z. palustris and Z. aquatica have served as a traditional food staple for Native Americans for centuries [9] and as a specialty commercial crop more recently (Hayes et al, 1989;Oelke, 1993). Z. latifolia was once an important grain in ancient China and has been cultivated as an aquatic vegetable because the young shoots become swollen, soft, and edible after being infected by the fungus Ustilago esculenta P. Henn (Thrower and Chan, 1980;Zhai et al, 2001;Guo et al, 2007).…”

Zizania latifolia (Griseb.) Turcz. ex Stapf was once utilized as an important grain in ancient China and has been cultivated as an aquatic vegetable. Here, we report the complete Z. latifolia chloroplast genome sequence obtained through de novo assembly of Illumina paired-end reads generated by directly purified chloroplast (cp) DNA genome sequencing. The Z. latifolia cp genome is 136,501 bp in length, comprising a pair of 20,878-bp inverted repeat regions (IR) separated by small and large single copy regions (SSC and LSC) of 12,590 and 82,155 bp, respectively. The Z. latifolia cp genome encodes 110 unique genes (77 protein-coding genes, 29 tRNA genes, and 4 rRNA genes), of which 15 encompass introns. Sequence analysis identified a total of 39 direct/inverted repeats and 63 simple sequence repeats (SSR) with an average rate of 0.46 SSRs/kb. Our results revealed that the Z. latifolia cp genome is AT-rich (61.02%) and gene codon usage may be largely affected by a low GC content and codon usage bias for A, T-ending codons. We predicted 33 RNA editing sites in the chloroplast of Z. latifolia, all for C-to-U transitions. Comparative analyses with other available Oryzeae plastid genomes showed that the coding and IR sequences were more conserved than the single-copy and non-coding regions, suggesting that the indels should be cautiously employed in phylogenetic studies. Phylogenetic analysis of 52 complete grass chloroplast genomes including the reported Z. latifolia cp genome in this study yielded an identical tree topology as previous plastid-based trees, providing strong support for a sister relationship between Bambusoideae+Pooideae and Ehrhartoideae in the BEP (Bambusoideae, Ehrhartoideae, Pooideae) clade of the grass family.
