It's not the first time that experts have claimed techniques could develop fruit with unusual features: scientists have already been looking at changing the color1 of kiwi fruit and bettering the taste of strawberries. But researchers inBrazilandIrelandsay such methods could also offer practical advantages, with hot tomatoes offering a new way of harvesting the pungent chemicals found in peppers known as capsaicinoids, which make food taste “hot”. “Capsaicinoids are valuable. They are used as painkillers and there are some researches showing that they promote weight loss,” said Agustin Zsogon from a Brazilian university, a co-author of a new article arguing for the benefits of engineering hot tomatoes. Writing in the journal Trends in Plant Science, the researchers say peppers are difficult crops to grow and low productive. Worse still, it is tricky to keep the pungency of the fruits table. By contrast, tomato production is high and the plant is well-studied. “You could produce the capsaicinoids in a more cost-effective manner,” said Zsogon. Tomatoes and peppers developed from a common ancestor, but separated about 19 million years ago. “All these genes to produce capsaicinoids exist in the tomato, they are just not active,” said Zsogon. “Using gene-editing technology, it is likely to switch these genes back on in tomatoes, making the fruit more special”, he said. 8. Why are the tomatoes made hot by the researchers? A. To test the gene-editing technology B. To improve the amount of the tomatoes C. To explore ways to harvest more capsaicinoids. D. To make the tomatoes more delicious. 9. For what purpose can capsaicinoids be used according to the text? 本文来源：https://www.wddqw.com/doc/868bccbe52e79b89680203d8ce2f0066f4336475.html
