iral rep gene, which leads to the synthesis of an essential protein for the replication of the virus. Consequently, without this protein, replication of the virus is compromised and the plants become resistant to the disease.
Safety and the way from research to seed market
Safety precautions for modern agricultural biotechnologies start at the very beginning of the research at the lab, and continue through the different phases of the development. Only when detailed scientific assessments determine it to be innocuous is the new development considered for commercial use. Prior to the submission for the commercial release, a comparison between the virus-resistant beans and its parental conventional/non-modified variety in all the ecosystems where the beans are cultivated in Brazil had been conducted by a consortium of 10 research centers over several years. Results showed that the transgenic beans do not differ in the environmental impact compared to its non-engineered parent beans. Additionally, the transgenic beans offer the advantage of reducing insecticides that have being used to kill the whiteflies that transmit the golden mosaic virus during the past decades. The new virus resistant beans are also considered as safe for consumption as the currently cultivated beans. On that ground, CTNBio, the multidisciplinary commission responsible for making science-based, technical assessments for the safety of genetically engineered products approved the beans for commercial release.
Approvals by CTNBio may be followed by an examination from the National Biosafety Council (CNBS) on the socio-economic convenience and opportunities of national interest.
There are in any case, further steps to be pursued on the way to market the seeds, such as the incorporation of the trait into cultivars suited to the different local conditions, the registration of the variety and production of the seeds. The following step is the law inspired by the UPOV Convention (International Union for the Protection of New Varieties of Plants), legis
