THE ARTICLEScientists discover gene to waterproof riceScientists have found a gene that will allow rice to survive longer in rice paddies that are under water. Plants under water for longer than a week receive so little oxygen they die. The scientists hope their discovery will mean the crops will last longer in regions that are regularly flooded. Rice growers in parts of Asia lose an estimated $US one billion annually to floods. They hope a new, stronger type of rice will reduce the financial damage that occurs in typhoon and monsoon seasons. They also hope they will get bumper harvests. This is good news for the millions of people who suffer from food shortages because of heavy rains. Rice production must increase by 30 per cent over the next 20 years for a billion people to receive their staple diet. The research is from teams from the University of California and the International Rice Research Institute. Their findings have been published in the science journal Nature. Dr David Mackill, one of the researchers, said scientists had been trying for 50 years to develop a breed of rice that can live under water. He explained that: “Attempts to breed [underwater] tolerance into commercially [profitable] rice failed to generate successful varieties." Another team member, Dr Pamela Ronald, said she hoped that the research would lead to new rice varieties that would mean a better food supply for poor farmers and their families. The discovery is sure to add to the debate on the need for genetically modified rice. WARM-UPS1. STAPLE FOOD: Look at these staple foods from around the world. Talk with your partner(s) about them. Research the ones you don’t know:
2. CHAT: In pairs / groups, decide which of these topics or words from the article are most interesting and which are most boring.
Have a chat about the topics you liked. For more conversation, change topics and partners frequently. 3. VERSATILE: Rice is one of the most useful foods in the world. Which of these ways of eating rice from around the world sound delicious to you?
4. QUICK DEBATE: Students A believe the water-resistant rice is a great idea. Students B believe any kind of genetically modified food is dangerous. Debate this with your partners. Change partners often. 5. OPINIONS: In pairs / groups, write down the opinions of the following people or creatures on the new water-resistant rice. Change partners and exchange opinions. Talk about whether or not you agree with these opinions.
