The development and commercialization of transgenic rice with novel traits in China may offer more opportunities for promoting rice productivity. Owing to the significance of rice as a major food crop in China, the enhancement of rice production is important for national food security. If left unaddressed, the po-tential biosafety concerns over the extensive release and commercial cultivation of transgenic rice may ham-per the development and application of this technology in rice improvement. Biosafety issues include: (1) ef-fects of toxic transgenes on non-target organisms; (2) transgene escape to crops or wild relatives through gene flow and its potential ecological consequences; (3) interactions and influences of transgenes and trans-genic plants on biodiversity, ecosystem functions, and soil microbes; and (4) the development of resistance to insect- or disease-resistant transgenes in target organisms. In order to safely and sustainably utilize transgenic biotechnology in rice, it is very important to assess biosafety consequences, including environmental risks, from transgenic rice. This paper presents a rational analysis of potential environmental biosafety problems based on the principles of risk assessment, provided that transgenic rice will be released for commercializa-tion. We hope these analyses will provide useful information for the decision-making on commercialization of transgenic rice and serve as a framework for the assessment of relevant environmental biosafety risks.
