Many countries have entered in trade and cultivation of transgenic plants. Some countries don’t enter in this area because of transgenic plants risk for the natural environment. However, most of countries have program on research and development about transgenic plants (even if there isn’t commerce of transgenic plants). In our country, numerous research centers and universities have researched on basic and applied science in the field of transgenic plants with different purposes. It is better to culture transgenic plants in transgenic plant greenhouse instead of conventional greenhouses to eliminate environmental concerns associated with transgenic plants producing research. Also, existences of these greenhouses are useful in commercialization, cultivation development and releasing studies of transgenic crops. Our country is very weak in transgenic greenhouse properties. Little scientific resources (or almost no) on this issue have been reported in published books and articles within the country; Thus, we aimed to in this paper to study the characteristics of transgenic greenhouses (especially in terms of structure and levels of biosafety).
