| description | How to use environmentally friendly technology to enhance rice field and grain quality is a challenge for the scientific community. Here, we showed that the application of molecular hydrogen in the form of hydrogen nanobubble water could increase the length, width, and thickness of brown/rough rice and white rice, as well as 1000-grain weight, compared to the irrigation with ditch water. The above results were well matched with the transcriptional profiles of representative genes related to high yield, including up-regulation of <i>heterotrimeric G protein β-subunit gene</i> (<i>RGB1</i>) for cellular proliferation, <i>Grain size 5</i> (<i>GS5</i>) for grain width, <i>Small grain 1</i> (<i>SMG1</i>) for grain length and width, <i>Grain weight 8</i> (<i>GW8</i>) for grain width and weight, and down-regulation of negatively correlated gene <i>Grain size 3</i> (<i>GS3</i>) for grain length. Meanwhile, although total starch content in white rice is not altered by HNW, the content of amylose was decreased by 31.6%, which was parallel to the changes in the transcripts of the amylose metabolism genes. In particular, cadmium accumulation in white rice was significantly reduced, reaching 52% of the control group. This phenomenon was correlated well with the differential expression of transporter genes responsible for Cd entering plants, including down-regulated <i>Natural resistance-associated macrophage protein</i> (<i>Nramp5</i>), <i>Heavy metal transporting ATPase</i> (<i>HMA2</i> and <i>HMA3</i>), and <i>Iron-regulated transporters</i> (<i>IRT1</i>), and for decreasing Cd accumulation in grain, including down-regulated <i>Low cadmium</i> (<i>LCD</i>). This study clearly showed that the application of molecular hydrogen might be used as an effective approach to increase field and grain quality of rice. |
