Natural variation in OsMYB8 confers diurnal floret opening time divergence between indica and japonica subspecies
The inter-subspecific indica - japonica hybrid rice confer potential higher yield than the widely used indica - indica intra-subspecific hybrid rice....

Genetic dissection of heterosis of indica–japonica by introgression line, recombinant inbred line and their testcross populations
The successful implementation of heterosis in rice has significantly enhanced rice productivity, but the genetic basis of heterosis in rice remains...

Two complementary genes in a presence-absence variation contribute to indica-japonica reproductive isolation in rice
Understanding the evolutionary forces in speciation is a central goal in evolutionary biology. Asian cultivated rice has two subspecies, indica and japonica...

Dissecting a heterotic gene through GradedPool-Seq map** informs a rice-improvement strategy
Hybrid rice breeding for exploiting hybrid vigor, heterosis, has greatly increased grain yield. However, the heterosis-related genes associated with...

Genome-wide transcriptome profile of rice hybrids with and without Oryza rufipogon introgression reveals candidate genes for yield
In this study, we compared genome-wide transcriptome profile of two rice hybrids, one with (test hybrid IR79156A/IL50-13) and the other without...

Genome-wide dissection of heterosis for yield traits in two-line hybrid rice populations
Heterosis has been widely utilized in agriculture and is important for world food safety. Many genetic models have been proposed as mechanisms...

Overcoming inter-subspecific hybrid sterility in rice by develo** indica-compatible japonica lines
Rice ( Oryza sativa L.) is an important staple crop. The exploitation of the great heterosis that exists in the inter-subspecific crosses between the indica...

Exploitation of heterosis loci for yield and yield components in rice using chromosome segment substitution lines
We constructed 128 chromosome segment substitution lines (CSSLs), derived from a cross between indica rice ( Oryza sativa L.) 9311 and japonica rice...

Breeding and study of two new photoperiod- and thermo-sensitive genic male sterile lines of polyploid rice (Oryza sativa L.)
Male sterile lines play an important role in the utilization of heterosis. To explore and exploit the heterosis of polyploid hybrid rice, two...

Genomic structural variation-mediated allelic suppression causes hybrid male sterility in rice
Hybrids between divergent populations commonly show hybrid sterility; this reproductive barrier hinders hybrid breeding of the japonica and indica ...

Root Morphological Traits and Spatial Distribution under Different Nitrogen Treatments and Their Relationship with Grain Yield in Super Hybrid Rice
Succeeding in breeding super hybrid rice has been considered as a great progress in rice production in China. This on-farm study was conducted with...

Molecular evolution of rice S 5 n and functional comparison among different sequences
The wide compatibility gene, S 5 n , can overcome embryo sac sterility between indica and japonica subspecies of rice. Therefore, it is very...

Advances in the understanding of inter-subspecific hybrid sterility and wide-compatibility in rice
Hybrid sterility is a major form of postzygotic reproductive isolation and frequently occurs in hybrids between divergent populations, such as the indica...
-
Mining rice new germplasm containing S 5 n gene by functional molecular marker and sequencing
Inter-subspecific hybrids between indica and japonica varieties yield strong biological heterosis, but it is difficult to utilize the hybrids...

Identifying neutral allele Sb at pollen-sterility loci in cultivated rice with Oryza rufipogon origin
Pollen sterility is commonly found in the intra-specific hybrids of indica and japonica rice, which is one of the main constrains for the utilization...
-
Experimental validation of inter-subspecific genetic diversity in rice represented by the differences between the DNA sequences of ‘Nipponbare’ and ‘93-11’
The pedigrees of three sequenced rice cultivars were analyzed to show that a majority of the genetic composition of ‘Nipponbare’ originates from japonica...
