Analysis of the Expressed Opinions on Gene Flow from Transgenic Plants and Its Effects on the Environment

World’s population is significantly increasing and food needed is decreasing. However, today the progress in the science especially plant biotechnology helps to improve food resources. Therefore, high yield and more stable cultivars are screened. At the moment due to the significant progress in plant biotechnology, limitation regarding genetic manipulations and gene transfer are being disappeared and researchers are capable to do breeding on importanttraits. In spite of advantages obtained by plant biotechnology some concerns still exist such as transfer of foreign genes from transgenic plants to herbs or other special from the same genes. The highest environmental concern regarding the gene flow from transgenics is related to transfer of genes into wild population of plants and its impact on environment. The effect of gene flow on the environment is its introgression into the genome of wild species. In order to block the negative environmental effects of gene flow on weeds and landraces, using gene flow barriers and mitigation of gene flow are very important. Molecular methods for controlling the gene flowbetween crops and weeds are based on maternal inheritance, male sterility and seed sterility. The distance adjustment of cultivation between transgenic and non- transgenic plants in a region could be a suitable strategy to decrease gene flow via pollen. According to these cases and the presence of transgenic crops on the market using this type of product which hascommercial any adverse effect has been not reported. According to the available resources and acreage, these productions annually increase that is embracing the use of these products.
