Worldwide, grain consumption is increased and grain prices are rising. This has led to a steady increase in the production of highly productive and more aff ordable genetically modifi ed (GM) crops. However, GM crops are highly concerned about potential environmental risks due to the introduction of external genes and genetic modifi cation. Therefore, it is essential to evaluate the environmental risk of genetically modifi ed organisms that can prove the safety of these GM crops. In this research, we analyzed the potential for weediness, unintended gene transfer, and viability in the natural environment for risk assessment of GM rice. To analyze the potential for weediness of GM rice, viviparous germination, shattering, and germination rate were measured. To analyze the potential release of the introduced gene into the environment by unintended gene transfer, the expression of the introduced gene through protein immune response and PCR was analyzed. The seed ger�mination rate of GM rice was measured from low temperature and frozen soil to analyze their survival ability in the natural environment. There was no signifi cant difference between GM rice and parent in all test items. Therefore, the weediness of GM rice did not occur. The items of the GMO risk assessment constructed in this research can be used as important basic material not only for rice but also for GM crops of various varieties.

Silicon and phosphorus are elements that are beneficial for plant growth. Despite the abundant availability of silicate and phosphate in the Earth’s crust, crop nutritional requirements for silicon and phosphorus are normally met through the application of fertilizer. However, fertilizers are one of the major causes of heavy metal pollution. In our study, we aimed to assess silicate and phosphate solubilization by the bacteria Enterobacter ludwigii GAK2, in the presence and absence of phosphate [Ca3(PO4)2] or silicate (Mg2O8Si3), to counteract cadmium stress in rice (Oryza sativa L). Our results showed that the GAK2-treated rice plants, grown in soil amended with phosphate [Ca3(PO4)2] or silicate (Mg2O8Si3), had significantly reduced cadmium content, and enhanced plant growth promoting characteristics including fresh shoot and root weight, plant height, and chlorophyll content. These plants showed significant downregulation of the cadmium transporter gene, OsHMA2, and upregulation of the silicon carrier gene, OsLsi1. Moreover, jasmonic acid levels were significantly reduced in the GAK2-inoculated plants, and this was further supported by the downregulation of the jasmonic acid related gene, OsJAZ1. These results indicate that Enterobacter ludwigii GAK2 can be used as a silicon and phosphorus bio-fertilizer, which solubilizes insoluble silicate and phosphate, and mitigates heavy metal toxicity in crops.
