Effects of Cd uptake, translocation and redistribution in different hybrid rice varieties on grain Cd concentration

Ecotoxicology and Environmental Safety, 2022
In order to identify the key transport process that determines the Cd concentration in brown rice, this study used 21 hybrid rice varieties as experimental materials and conducted field experiments in Qiyang (cadmium-contaminated site) and Yongding (low ...

Resequencing of 1,143 indica rice accessions reveals important genetic variations and different heterosis patterns

Nature Communications, 2020
Hybrid rice cultivars are widely planted around the world. Here, the authors resequence 1,143 indica accessions, focusing on the parents of superior hybrid rice lines in China, and reveal genetic loci that are associated with heterosis via measuring ...

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.

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.

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
