Recently, researchers at Nagoya University in Japan announced that they have discovered a new gene that can increase rice production by 50%. This gene can be passed on to the next generation through natural hybridization without involving the controversial issue of genetic modification.
According to reports, this gene named "WEP" was discovered by researchers at the Nagoya University Biological Function Development and Utilization Research Institute and is located in the eighth chromosome of the rice chromosome. Its function is to control the primary branch of rice (most The number of young ear branches that begin to grow out of the ear nodes, and generally speaking, the more rice branches, the more rice grains are formed. According to reports, the researchers crossed a rice variety called "ST-12" (the variety has three times more stems than ordinary rice) with the ordinary rice variety "Nipponbare" and analyzed the obtained hybrids. The rice gene eventually discovered this new gene. Further investigation revealed that at the stage of forming ears of "ST-12", the amount of WEP gene found in its plants was nearly ten times more than that of ordinary "Nipponbare", thus confirming that it had a great effect on the formation of a branch enhancement.
It is said that researchers at Nagoya University discovered a gene that can increase the number of rice grains in 2005. The researchers implanted this gene called "Gn1" together with the "WEP" gene discovered this time. The plants of "Nipponbare" found that the number of stems per branch increased more than three times, and the number of seeds per plant also increased by 51%.
At present, about 50% of the calories taken by humans worldwide come from rice, wheat and corn. Meat such as cows, pigs, and chickens needs to be fed with 11 times, 7 times, and 4 times the amount of meat to obtain the same amount of meat. Therefore, if you want to avoid a food crisis without reducing your living standards, you must It is necessary to increase the output of major crops such as rice, wheat and corn on a large scale. This discovery by Japanese researchers will provide a new way for humanity to solve the future food crisis.
