Pyramiding three bacterial blight resistance genes (xa5, xa13 and Xa21) using marker-assisted selection into indica rice cultivar PR106
TLDR
Genes in combinations were found to provide high levels of resistance to the predominant Xoo isolates from the Punjab and six races of Xoo from the Philippines, and Xa21 was the most effective, followed by xa5. Expand
Doubling genome size without polyploidization: dynamics of retrotransposition-driven genomic expansions in Oryza australiensis, a wild relative of rice.
TLDR
This study shows that Oryza australiensis, a wild relative of the Asian cultivated rice O. sativa, has undergone recent bursts of three LTR-retrotransposon families, leading to a rapid twofold increase of its size. Expand
Phylogenetic relationships among Oryza species revealed by AFLP markers
TLDR
AFLP is reliable molecular technique and provides one of the most informative approaches to ascertain genetic relationships in Oryza, which may also be true for other related species/organisms. Expand
Identification and mapping of the QTL for aluminum tolerance introgressed from the new source, ORYZA RUFIPOGON Griff., into indica rice (Oryza sativa L.)
TLDR
The results indicate the possibilities to use marker-assisted selection and pyramiding QTLs for enhancing Al tolerance in rice and the evolutionary genetics of plant adaptation to acid-soil conditions across cereal species. Expand
Genomic paleontology provides evidence for two distinct origins of Asian rice (Oryza sativa L.)
TLDR
Experimental data provide additional evidence for the proposal that Indica and Japonica rice arose from two independent domestication events in Asia. Expand
Alien introgression in rice
TLDR
The rapid recovery of recurrent phenotypes in BC2 and BC3 generations from wide crosses is an indication of limited recombination and cytogenetic and molecular investigations are required to determine precisely the mechanism of introgression of small chromosome segments from distant genomes in the face of limited homoeologous chromosome pairing. Expand
Functional characteristics of an endophyte community colonizing rice roots as revealed by metagenomic analysis.
TLDR
The first metagenomic approach to analyze an endophytic bacterial community resident inside roots of rice, one of the most important staple foods, suggests a high potential of the endophyte community for plant-growth promotion, improvement of plant stress resistance, biocontrol against pathogens, and bioremediation, regardless of their culturability.

Assessment of Genetic Diversity of Philippine Rice Cultivars Carrying Good Quality Traits using SSR Markers
TLDR
The study revealed that SSR markers facilitated the classification of these quality rice cultivars according to their subspecies, and exhibited a higher genetic diversity and therefore very useful for rice breeding programs, especially for genetic mapping studies and eventually for application of marker-assisted selection (MAS) in the programs. Expand
High-resolution mapping of two rice brown planthopper resistance genes, Bph20(t) and Bph21(t), originating from Oryza minuta
TLDR
This is the first report of BPH resistance genes from the wild species O. minuta and these two new genes and markers reported here will be useful to rice breeding programs interested in new sources of B PH resistance. Expand
Genetic diversity and phylogenetic relationship as revealed by inter simple sequence repeat (ISSR) polymorphism in the genus Oryza
TLDR
ISSR analysis suggests that the genus Oryza may have evolved following a polyphyletic pathway, and is useful in the fingerprinting of cultivated and wild species germplasm, and in understanding the evolutionary relationships of Oryzo. Expand
