Researchers at the National University of Singapore have successfully modified the genes used to make ethylene gas in plants. Ethylene gas has the effect of promoting plant maturation. Ng Eng, an associate professor of biology at the National University of Singapore, said that after the gene is modified, the fruit will produce 90% less ethylene than it normally does. Scientists are currently conducting research on best-selling fruit bananas that will bring in $1.5 billion in annual profits. Engel said: Bananas are too easy to rot. Fruit makers are now using expensive refrigerated systems when transporting bananas, otherwise bananas will not be delivered to their destinations. By modifying the gene, one can stop the fruit from producing ethylene gas. In this way, we can transport bananas without refrigeration equipment, so that bananas can be delivered to the market without deterioration. Engel said that in addition to extending fruit ripening time, scientists can accurately control the ripeness and decay of fruit. He said: In the few days before these bananas were sold, people could treat them with ethylene gas. After processing, these bananas will mature normally. However, researchers from the National University of Singapore stated that they currently only successfully applied the genetic modification system to Arabidopsis plants. It takes about two years to apply this technology to bananas.
