If you give you a bowl of blue rice, do you dare eat it? It sounds like fantasy things, it is possible in the near future become reality. Reporter on Nov. 18 from the Ocean University of China noted that a large sea Professor Xue-Cheng Zhang has successfully cloned phycocyanin gene, and into rice endosperm genome. Haida has also led the country with the Yuan Longping Hybrid Rice Research Center was officially signed to jointly develop a new type of rice with sea gene. It is learned that belong to cyanobacteria Spirulina, containing the rice gene Phycocyanin, started from seed will be blue, while the rice is also grown up from the ordinary white to blue, which means that people usually eat rice To become a "blue-meter."Professor cloned gene took six years18 pm, the reporter interviewed a large sea of Marine Life Sciences Professor, Xue-Cheng Zhang, Xue-Cheng Zhang this year has been 68 years of research in the life of the algae. "In 2002, when Yuan Longping commissioned his doctoral Bing-Ran to contact me, hope to develop genetic resources for algae to grow improved rice cultivation techniques, and I see the future as well, they agreed to cooperate. That year At first, I took my doctorate and graduate students beginning research in this area. "Xue-Cheng Zhang was able to own both the results and people's livelihood," the main battlefield, "inspired by the combination, but also understand the hardships involved in new areas, he was working 10 hours a day, sometimes even the food was no time to eat.Xue-Cheng Zhang of the road was not smooth in the middle walked a lot of detours, "This project studies the world, very few people, only themselves to open up, I was initially trying to Spirulina and other algae in the DNA 'broken ', then moved to Rice in the restructuring, the emergence of new traits in selected varieties of rice plants, experiment many times without success. "at the end of 2007, Xue-Cheng Zhang suddenly thought of using cloning meth ods," I would like cloned algae on useful function of human genes, and then moved into rice genes using cloned chloroplast DNA, so that you can increase the photosynthetic efficiency of rice and to improve the nutritional quality of rice. "In early October of this year, Xue-Cheng Zhang finally cloned the gene phycocyanin in Spirulina, then into rice endosperm, and patented technology.Yuan Longping jointly developed handIn Xuecheng phycocyanin gene cloning and successfully moved to after the rice endosperm, in October, he and Vice President of the sea more than appropriate law went to Changsha to visit the National Hybrid Rice Research Center, met with the "Father of Hybrid Rice", the Chinese Academy of Engineering, China National Hybrid Rice Research Centre Yuan Longping, agreed with the Chinese "father of hybrid rice" common development of new marine rice. Big Sea with China National Hybrid Rice Research Center was officially signed to jointly launch the "Import of marine b iological functions create new rice germplasm" research.Xue-Cheng Zhang said the solar energy utilization efficiency of Spirulina is 10% to 15%, up to 18%, much higher than normal plants, light use efficiency of rice less than 4%, the new rice photosynthesis will greatly increase. Reporters then contacted the Yuan Longping doctorate Bing-Ran, "We hope to bring more marine functional gene into rice, the per mu yield of hybrid rice has now reached 800 kg, reached its peak, output has been very difficult. And by transfer of light-harvesting Spirulina Phycocyanin genes related to broaden the absorption spectrum of rice could improve the photosynthetic efficiency of rice, will be able to achieve the objective of increasing production. "Bing-Ran said that currently they are being screened transgenic rice lines, but what the new rice can not determine when to launch, but also some technical problems yet to be defeated."Ocean of rice," is expected to drink the sea waterXue-Cheng Zha ng told reporters that if this new type of rice with sea gene to study successfully, and successfully moved into salt-tolerant gene, then in the near future, the rice is likely to use irrigation water. "Throughout the growth period of rice in the rice fields are required filled with water, a huge demand on water resources, but China is a dry country, which will contain the sea salt tolerance to transgenic rice, the train can use sea water irrigation of rice, will greatly reduce the water demand. "Xue-Cheng Zhang said China's annual rice cultivation are major water users, if we can use water for irrigation, then the fresh water savings and funding is very significant.Salt tolerant rice can not only save water, but also in the coastal beach, to promote cultivation of saline. "Tidal land and saline as well as the general means that low-yield crops, but if large area containing the new salt-tolerant gene in rice, then let the rice fragrance saline no longer a dream." Xue-Cheng Z hang told reporters that although the marine life in the The salt-tolerant rice gene immigration is still very difficult, but if this vision realized, will increase the development of cultivated land and a profound impact on food production.About SpirulinaSpirulina is a kind of lower plants, belonging to Cyanophyta Oscillatoria algae Division. They, like bacteria, cell nucleus is not true, so also known as cyanobacteria. The original cell structure of cyanobacteria, and very simple, first appeared on earth photosynthetic organisms, has been living on this planet 35 million years. It grows in water, its shape can be seen under the microscope for the spiral filaments, hence the name. Hundreds of years ago, some African tribes will be made from algae Spirulina eat cake. In recent decades, scientists have found that Spirulina was found in humans so far, the best natural food source of protein, and protein content as high as 60% to 70%, equivalent to 6 times the wheat, and the ab sorption rate of 95% or more. The unique phycocyanin, can increase lymphocyte activity and enhancing immunity."Blue rice" Benefits"Change is not just the color of rice, the new rice is not only color, flavor and the United States, but also will greatly increase the nutritional value, 'Food and Drug homology', 'eat their way to health,' and will be able to achieve our dinner table. "Xuecheng description, this" blue "makes the original paddy rice depends on the missing amino acids are effectively added. Lai has the amino acid for osteoporosis prevention and treatment, and strengthen the body's immunity. Phycocyanin also has to improve immunity, inhibition of tumor and anti-virus and other important physiological functions, which also contains the kind of hormone called calcitonin, can effectively promote the absorption of calcium.
