Cultivation of salt tolerant and drought tolerant crops by transgenic methods

Tianjin Science and technology support program project "plant bioengineering breeding of salt tolerant and drought tolerant diesel oil in North China" chaired by experts from Tianjin Agricultural College, through research, plant diesel oil can be extracted and refined This kind of diesel oil not only has the characteristics of low cost, small pollution, high safety and regeneration, but also has a better combustion performance than No.0 refined diesel oil, and the use of plant diesel oil does not need to be modified The research has reached the leading level in China The reporter learned that at present, the diesel oil production is obtained through the refining method of petrochemical industry, which seriously pollutes and damages the environment, and is non renewable resources Biodiesel is a kind of renewable diesel fuel, which can replace petrochemical diesel oil by transesterification process It uses oil crops, wild oil plants, engineering microalgae and other aquatic plant oil, animal oil and catering waste oil as raw materials The cost of biodiesel extracted by plant processing technology is about one-third less than that of refined diesel, which can control the environmental pollution to the minimum and is also a renewable resource The blending of vegetable diesel and petrochemical diesel in a certain proportion can reduce fuel consumption, improve power performance and reduce exhaust pollution In addition, vegetable diesel also has good low-temperature engine starting performance It can start the engine at - 20 ℃ without additives In Tianjin plant diesel breeding project, HS transcription factor gene was introduced into diesel plants such as sunflower, soybean and Xanthoceras for the first time through transgenic method, and a batch of test tube seedlings and potted seedlings were cultivated Two types of sunflower and soybean mutants with significantly enhanced salt and drought tolerance were obtained, which laid a foundation for the cultivation of diesel plants in saline alkali soil Experts believe that the research results of the project have the triple effects of ecology, energy and economy It will play a positive role in improving farmers' income and alleviating the energy crisis through the effective utilization of saline alkali land and dry wasteland.
