Phylogeography of Asian wild rice, Oryza rufipogon: a genome-wide view.
Asian wild rice (Oryza rufipogon) that ranges widely across the eastern and southern part of Asia is recognized as the direct ancestor of cultivated Asian rice (O. sativa). Studies of the geographic structure of O. rufipogon, based on chloroplast and low-copy nuclear markers, reveal a possible phylogeographic signal of subdivision in O. rufipogon. However, this signal of geographic differentiat...
متن کاملIdentification of trait-improving quantitative trait loci alleles from a wild rice relative, Oryza rufipogon.
Wild species are valued as a unique source of genetic variation, but they have rarely been used for the genetic improvement of quantitative traits. To identify trait-improving quantitative trait loci (QTL) alleles from exotic species, an accession of Oryza rufipogon, a relative of cultivated rice, was chosen on the basis of a genetic diversity study. An interspecific BC2 testcross population (V...
متن کاملProximate nutritional composition and antioxidant properties of Oryza rufipogon, a wild rice collected from Malaysia compared to cultivated rice, MR219
Wild rice (Oryza rufipogon L) is known as an important germplasm that has specific desirable attributes and a high genetic diversity. The physicochemical and antioxidant properties of O. rufipogon Griff. (acc. IRGC105491), a wild rice collected from Malaysia that was used in a breeding program and a QTL mapping study, were assessed to determine the rice’s nutritional value compared with a commo...
متن کاملMorphological and Molecular Data Reveal Three Distinct Populations of Indian Wild Rice Oryza rufipogon Griff. Species Complex
Wild relatives of crops possess adaptive mutations for agronomically important traits, which could play significant role in crop improvement for sustainable agriculture. However, global climate change and human activities pose serious threats to the natural habitats leading to erosion of genetic diversity of wild rice populations. The purpose of this study was to explore and characterize India'...
متن کاملGenomic dissection of small RNAs in wild rice (Oryza rufipogon): lessons for rice domestication.
The lack of a MIRNA set and genome sequence of wild rice (Oryza rufipogon) has prevented us from determining the role of MIRNA genes in rice domestication. In this study, a genome, three small RNA populations and a degradome of O. rufipogon were sequenced by Illumina platform and the expression levels of microRNAs (miRNAs) were investigated by miRNA chips. A de novo O. rufipogon genome was asse...
