German scientists have recently been approved by the relevant government departments to begin trials of a new type of genetically modified potatoes. According to scientists, unlike other GM crops that have directly changed crop traits, new crops will rely on foreign genes to improve the "breathing" system for healthy growth. According to a press release issued by the German Max Planck Institute, the new genetically modified potatoes will be implanted with exotic genes obtained from leguminous plants such as kidney beans to produce a special protein in the potatoes. Scientists explained that both humans and animals have a respiratory system that can deliver oxygen to circulate, while plants rely on gas diffusion to deliver the gas in the body. The newly implanted genes will be responsible for the oxygen transfer and storage in the potatoes to achieve the purpose of improving the growth of the crops. Scientists said that trial planting new crops is not only hoping to obtain more healthy potatoes, but also hope to deep understand the interrelationship between oxygen supply and material exchange in plants through experiments to help improve agricultural production technology in the future.
