The genetically modified RF3 canola strain is a canola strain obtained by conventional breeding crosses with the male sterile oilseed rapeseed strain MS8 and non-transgenic rapeseed.
Canola is one of the most important vegetable oilseed crops. To avoid the herbicide challenge, the RF3 line containing the bar gene and the barstar gene were designed, which act as sources of glufosinate resistance and restore fertility in hybrid lines.
To evaluate the food safety of the transgenic RF3 canola strain, 2.5%, 5%, and 10% genetically modified RF3 canola and its non-GMO isogenic line were formulated as a feed regimen for rats. Subsequently, general growth and toxicological parameters, as well as the effects on the gut microbiota of the rats, were evaluated. At the end of the period, several significant differences were observed among the rats in body weight, feed intake, relative organ weight, hematology, and serum biochemistry. In conclusion, based on this 90-day feeding test and gut microbiota analysis, the genetically modified RF3 canola strain is considered as safe and healthy as non-GMO canola.
In the test, analysis, measurement and evaluation studies carried out in our organization, national and international standards and applicable legal regulations are complied with and reliable and impartial results are obtained. These studies are based on the latest technological equipment, trained and experienced staff and modern methods. Among the numerous tests carried out in this context, RF3 canola type determination and quantity analysis services are also available.
