Molecular and Morphological Divergence of Australian Wild Rice

Plants, 2020
Two types of perennial wild rice, Australian Oryza rufipogon and a new taxon Jpn2 have been observed in Australia in addition to the annual species Oryza meridionalis. Jpn2 is distinct owing to its larger spikelet size but shares O.

Genotypic Variation in Spatial Distribution of Fe in Rice Grains in Relation to Phytic Acid Content and Ferritin Gene Expression

Rice Science, 2020
Rice varieties having high Fe concentration in the endospermic region can be used as a good source for Fe deficit population. In this study, 303 Oryza sativa varieties and 1 Oryza rufipogon accession were assessed for spatial Fe accumulation in grains by

Genetic Diversity and Structure of Oryza rufipogon Griff. Populations in the Philippines [PDF]

Philippine Journal of Science, 2020
ABSTRACT Oryza rufipogon Griff. or ‘Rufi’ is the wild progenitor of the cultivated rice, Oryza sativa L. In the Philippines, Rufi was previously known to be found only in Lake Apo, Bukidnon.

Association Mapping of Quantitative Trait Loci for Grain Size in Introgression Line Derived from Oryza Rufipogon

Rice Science, 2020
Grain size is one of the critical agronomic traits governing grain yield and quality in rice. However, the underlying genetic mechanisms that control grain size in rice are poorly understood.

Reticulate Evolution in AA-Genome Wild Rice in Australia

Frontiers in Plant Science, 2022
The wild rice gene pool, i.e., AA-genome, in Australia is geographically and genetically distinct from that in Asia. Two distinct taxa are found growing together in northern Australia, Oryza meridionalis (including annual and perennial forms) and an ...

Evolution of Plant Architecture in Oryza Driven by the PROG1 Locus

Frontiers in Plant Science, 2020
The genetic control of plant architecture in crops is critical for agriculture and understanding morphological evolution. This study showed that an open reading frame (ORF) of the rice domestication gene PROG1 appeared 3.4–3.9 million years ago (Mya ...

Pan-genome inversion index reveals evolutionary insights into the subpopulation structure of Asian rice

Nature Communications, 2023
Pan-genomes provide useful resources for evolutionary studies, functional genomics and breeding of cultivated plants. Here, the authors report a new rice pan-genome including 73 Asian rice and two wild relatives (Oryza rufipogon and O.

Genome-Wide Analysis of WRKY Genes and Their Response to Salt Stress in the Wild Progenitor of Asian Cultivated Rice, Oryza rufipogon

Frontiers in Genetics, 2020
The WRKY gene family is widespread in plants, which plays key roles in plant development and stress response. Although WRKY transcription factors have been widely characterized in many plants, a genome-wide analysis of the WRKY gene family is lacking in ...

Characterization of Oryza rufipogon–Derived Resistance to Tungro Disease in Rice [PDF]

Plant Disease, 2007
Rice tungro disease (RTD) is caused by the interaction between Rice tungro spherical virus (RTSV) and Rice tungro bacilliform virus (RTBV), both of which are transmitted by green leafhoppers (GLH). In order to define the resistance against RTD in rice cv. Matatag 9 which was developed by interspecific hybridization between RTD-susceptible cv. IR64 and

Table_5_Phenotypic Variation and the Impact of Admixture in the Oryza rufipogon Species Complex (ORSC).xlsx

, 2022
Crop wild relatives represent valuable reservoirs of variation for breeding, but their populations are threatened in natural habitats, are sparsely represented in genebanks, and most are poorly characterized.
