Fine mapping of GS2, a dominant gene for big grain rice

Crop Journal, 2013
Grain shape as a major determinant of rice yield and quality is widely believed to be controlled by quantitative trait loci (QTL). We have identified a novel gene “GS2” to largely regulate grain length and width in rice.

Spike-Stalk Injection Method Causes Extensive Phenotypic and Genotypic Variations for Rice Germplasm

Frontiers in Plant Science, 2020
Genetic diversities or favorable genes within distantly related species are the important resources for crop genetic improvement and germplasm innovation.

Overexpression of OsLCT2, a Low-Affinity Cation Transporter Gene, Reduces Cadmium Accumulation in Shoots and Grains of Rice

Rice, 2021
Cadmium (Cd)-contaminated rice is a serious issue affecting food safety. Understanding the molecular regulatory mechanisms of Cd accumulation in rice grains is crucial to minimizing Cd concentrations in grains.

OsLAP6/OsPKS1, an orthologue of Arabidopsis PKSA/LAP6, is critical for proper pollen exine formation

Rice, 2017
Background Male fertility is crucial for rice yield, and the improvement of rice yield requires hybrid production that depends on male sterile lines.

Hybrid Vigour and Hybrid Mimics in Japonica Rice

Agronomy, 2022
In crop improvement programs, hybrid vigour (heterosis) is an important breeding strategy but the molecular mechanisms of hybrid vigour are still unclear. Grain yield declines after F1 generation due to phenotypic segregation. We found that, at the early seedling stage in hybrids derived from the temperate japonica rice varieties ‘Doongara’ and ‘Reiziq’

Identification of a New Wide-Compatibility Locus in Inter-Subspecific Hybrids of Rice (Oryza sativa L.)

Agronomy, 2022
As a special class of rice germplasm, wide-compatibility varieties (WCVs) guarantee the fertility of hybrids when there is cross-fertilization between two subspecies.

Is one‐line hybrid rice coming? [PDF]

Journal of Integrative Plant Biology, 2019
Hybrid rice proved to be high‐yielding and is of great importance to food safety worldwide. By using gene editing techniques, we generated one‐line hybrid rice by preventing meiosis from occurring, which can largely contribute to maintaining the hybrid dominance.

Effect of elevated CO2 and high temperature on seed-set and grain quality of rice [PDF]

, 2012
Hybrid vigour may help overcome the negative effects of climate change in rice. A popular rice hybrid (IR75217H), a heat-tolerant check (N22), and a mega-variety (IR64) were tested for tolerance of seed-set and grain quality to high-temperature stress at

A method for mechanized hybrid rice seed production using female sterile rice

Rice, 2019
Background The breeding and large-scale adoption of hybrid rice is an important achievement in modern agriculture. Mechanized seed production is urgently needed for widespread adoption of hybrid rice because it can compensate for the shortage of manual ...
