Traits improvement of wild rice O. rufipogon via multiplex genome editing

Journal of Integrative Plant Biology
Multiplex genome editing of seven genes for the rapid improvement of target traits in wild rice Oryza rufipogon produced lines with enhanced agronomic traits, including erect plant architecture, shortened awns, yellowish hull color, reduced seed shattering, white-colored pericarps, and other improvements.

The 172-kb genomic DNA region of the O. rufipogon yld1.1 locus: comparative sequence analysis with O. sativa ssp. japonica and O. sativa ssp. indica

Functional & Integrative Genomics, 2008
Common wild rice (Oryza rufipogon) plays an important role by contributing to modern rice breeding. In this paper, we report the sequence and analysis of a 172-kb genomic DNA region of wild rice around the RM5 locus, which is associated with the yield QTL yld1.1.

Large-scale DNA polymorphism study of Oryza sativa and O. rufipogon reveals the origin and divergence of Asian rice

Theoretical and Applied Genetics, 2007
Polymorphism over approximately 26 kb of DNA sequence spanning 22 loci and one region distributed on chromosomes 1, 2, 3 and 4 was studied in 30 accessions of cultivated rice, Oryza sativa, and its wild relatives. Phylogenetic analysis using all the DNA sequences suggested that O. sativa ssp. indica and ssp.

Genetic structure of three Oryza AA genome species (O. rufipogon, O. nivara and O. sativa) as assessed by SSR analysis on the Vientiane Plain of Laos

Conservation Genetics, 2006
Microsatellite (SSR) markers can reveal a high level of polymorphic loci, and are increasingly being used in population genetic structure studies. On the Vientiane plain of Laos all components of the rice crop complex exist, wild annual (O. nivara), wild perennial (O. rufipogon) and weedy relatives of rice as well as rice itself.

Genetic architecture of ecological divergence between two wild rice species (Oryza rufipogon and O. nivara)

2023
Ecological divergence due to habitat difference plays a prominent role in the formation of new species but the genetic architecture during ecological speciation and the mechanism underlying phenotypic divergence remain less understood. Two wild rice species (O. rufipogon and O. nivara) are a progenitor-derivative species pair with ecological divergence

Identification of a Drought Tolerant Introgression Line Derived from Dongxiang Common Wild Rice (O. rufipogon Griff.)

Plant Molecular Biology, 2006
Construction of introgression lines using cultivated rice as recipient and wild rice is a novel approach to explore primitive and broad genetic resources in rice breeding. We recently generated a set of 159 introgression lines via a backcrossing program using an elite Indica cultivar rice Guichao 2 (O. sativa L. ssp.

Molecular marker-assisted selection for yield-enhancing genes in the progeny of “9311×O. rufipogon” using SSR

Euphytica, 2004
Oryza rufipogon (IRGC105491) is a wild relative of cultivated rice, it contains two favorable yield-enhancing genes (yld1.1 and yld2.1) on chromosomes 1 and 2, respectively, which are capable of improving the yield of hybrid rice by 18 and 17%, respectively.

Clonal performance of perennial Oryza sativa/O. rufipogon selections and their combining ability with O. sativa cultivars for survival, stolon production and yield

Field Crops Research, 2007
Abstract In Southeast Asia, upland rice (Oryza sativa) is an annual crop typically grown for subsistence on hilly lands that are at risk for soil erosion. If perennial cultivars of upland rice were developed, they would provide farmers with an inexpensive tool to produce a preferred food while conserving soil. O.

Fine mapping of a yield-enhancing QTL cluster associated with transgressive variation in an Oryza sativa × O. rufipogon cross

Theoretical and Applied Genetics, 2007
A high-resolution physical map targeting a cluster of yield-related QTLs on the long arm of rice chromosome 9 has been constructed across a 37.4 kb region containing seven predicted genes. Using a series of BC3F4 nearly isogenic lines (NILs) derived from a cross between the Korean japonica cultivar Hwaseongbyeo and Oryza rufipogon (IRGC 105491), a ...

Ecological divergence in the presence of gene flow in two closely related Oryza species (Oryza rufipogon and O. nivara)

Molecular Ecology, 2010
Ecological divergence plays a prominent role in the process of speciation, but how divergence occurs in the face of gene flow is still less clear, and remains controversial among evolutionists. Here we investigated the nucleotide diversity, divergence and gene flow between Oryza nivara and O.
