Construction of introgression lines of Oryza rufipogon and evaluation of important agronomic traits
Theoretical and Applied Genetics, 2018Cultivated rice (Oryza sativa) originated from common wild rice (Oryza rufipogon) and inherited its advantages. However, during the rice domestication process, some valuable features of wild rice, such as tolerance to biotic and abiotic stress, were lost.

Genetic diversity in the northernmost Oryza rufipogon populations estimated by SSR markers
Theoretical and Applied Genetics, 2003To estimate genetic diversity of the residual northern populations of Oryza rufipogon, a total of 232 individuals from six populations were analyzed using microsatellites (SSRs). The O. rufipogon populations with different status included three from Dongxiang (Jiangxi Province) and three from Chaling (Hunan Province) in China.

Nucleotide polymorphism in the Adh1 locus region of the wild rice Oryza rufipogon
Theoretical and Applied Genetics, 2004Nucleotide variation in the alcohol dehydrogenase (Adh1) locus region of the wild rice Oryza rufipogon and its related species was analysed to clarify the maintenance mechanism of DNA variation in Oryza species. The estimated nucleotide diversity in the Adh1 locus region of O.

Genetic architecture of ecological divergence between Oryza rufipogon and Oryza nivara
Molecular EcologyAbstractEcological 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 ancestors of rice (Oryza rufipogon and Oryza nivara) are a progenitor‐derivative species pair with ...

Plant regeneration from protoplasts of wild rice (Oryza rufipogon Griff.)
Plant Cell Reports, 1991Embryogenic callus initiated from basal segments of micropropagated shoots of Oryza rufipogon were used to initiate cell suspension cultures. After approximately 3 months these cultures were capable of yielding large numbers of protoplasts which underwent sustained division in agarose-solidified medium at a frequency comparable to that observed with ...

Identification of SUB1A alleles from wild rice Oryza rufipogon Griff.
Genetic Resources and Crop Evolution, 2011Submergence stress is a major constraint to rice production in South and Southeast Asia. Most rice (Oryza sativa L.) cultivars die within a week of complete submergence, while a small number of accessions are submergence-tolerant for up to 2 weeks or more.

Intra-Population Genetic Structure of Oryza rufipogon Griff. in Yunnan, China
Journal of Plant Research, 2001Griff., allozyme analysis was conducted using 22 loci on a typical population from Yunnan Province, China. Non-random distribution of genotypes and/or genetic variability was found among three subpopulations, and the result was further demonstrated by considerable genetic differentiation observed (FST=0.206) within the population.
