Genetically Modified Rice

چکیده
Plant breeding, the science of crop production, has traditionally developed new cultivars through selective breeding in the spirit of Gregor Mendel (1965) and his peas. Plant breeders hybridize plants that have been selected for some desired trait. By hybridizing desirable plants, desirable alleles—and combinations of alleles—are concentrated, thereby improving the fitness of the offspring. Plant breeders then test the new genotypes in different environments in order to compare the fitness of offspring against their parents in hope of improving the progeny’s performance across a greater range of environmental conditions.

Study and Comparison of Genetically and Non-Genetically Modified Rice from View Point of Possibility of Gene Transferring in Blood of Labouraty Animal
Introduction: Genetically modified plants species of plants are produced by the genetic engineering of agricultural science and the addition of specific genes in their genetic sequences with the aim of optimizing the product and creating desirable traits. This study examined the remains of Cry1A(b) and P35 genes in blood of rats fed with genetically modified rice. Methods: This study was exper...
متن کاملMonitoring of Genetically Modified Rice among Some Imported Rice Samples in Iran
Background: Genetically Modified (GM) foods are produced using genetic engineering. This survey attempted to identify the presence of GM rice varieties among some imported rice samples in Iran. Methods: From May to July 2016, a total of 50 samples of the imported rice to Iran were obtained, including 20 bulk rice samples from Bandar Abbas custom, Southern Iran and 30 retail rice samples from s...
متن کاملEffect of Genetically Modified Rice on Some Intestinal Microbial Flora in Rats
Background and purpose: Transgenic rice is a type of rice that its genetic sequence has been changed to improve its quantity and quality. Bt (Bacillus thuringiensis) transgenic rice expresses Cry1Ab protein and is named Tarom Molaii. There are no studies on the effect of this type of transgenic rice on gastrointestinal health in Iran, so, this study investigated the effect of Tarom Molaii tran...
متن کاملEffects of genetically modified T2A-1 rice on the GI health of rats after 90-day supplement
Bacillus thuringiensis insecticidal toxin (Bt) rice will be commercialized as a main food source. Traditional safety assessments on genetically modified products pay little attention on gastrointestinal (GI) health. More data about GI health of Bt rice must be provided to dispel public' doubts about the potential effects on human health. We constructed an improved safety assessment animal model...
متن کاملComparison of ileal digested production of parental rice and rice genetically modified with cowpeas trypsin inhibitor.
OBJECTIVE To compare the ileal digestibility of protein and amino acids in parental rice and rice genetically modified with sck gene. METHODS Six experimental swines were surgically fixed with a simple T-cannula at the terminal ileum and fed with parental rice and rice genetically modified with sck gene alternately. The ileum digesta were collected and analyzed for determination of apparent a...
متن کاملImmunotoxicological Evaluation of Genetically Modified Rice Expressing Cry1Ab/Ac Protein (TT51-1) by a 6-Month Feeding Study on Cynomolgus Monkeys
The present study was performed to evaluate the food safety of TT51-1, a new type of genetically modified rice that expresses the Cry1Ab/Ac protein (Bt toxin) and is highly resistant to most lepidopteran pests. Sixteen male and 16 female cynomolgus monkeys were randomly divided into four groups: conventional rice (non-genetically modified rice, non-GM rice), positive control, 17.5% genetically ...
