[00:07.05]The American company Monsanto has announced what it calls a major development in efforts to identify all of the genes 2 found in rice.
[00:18.49]It says scientists working in the United States have produced the first plans for a genetic 3 map of the rice plant.
[00:28.24]Monsanto says it will share its information freely with other researchers around the world.
[00:35.89]The company says it hopes the findings will lead to increased production of the food crop.
[00:43.18]Monsanto Company researchers made the announcement in Beijing, China.
[00:48.80]China is the largest producer of rice in the world.
[00:53.26]Rice is the world's most popular food grain.
[00:58.04]Last year, almost 600,000,000 tons of rice were grown around the world.
[01:04.81]However, Monsanto notes that current rice production levels will not meet the needs of a growing world population twenty-five years from now.
[01:16.54]The work on the rice plant gene 1 map was done mainly in the laboratories of Leroy Hood 4 at the University of Washington in Seattle.
[01:27.98]Mister Hood and his team used a method known as gene sequencing to make a map of the genetic material.
[01:37.57]The map is said to be about 85% complete.
[01:43.00]Monsanto provided financial support for the work.
[01:47.62]The company says it will provide all of the information to the International Rice Genome Sequencing Project.
[01:56.45]This project includes ten research teams around the world working to produce the complete genetic map of rice.
[02:06.41]The company's announcement means a complete map of the genetic material of rice could be finished within three years.
[02:16.54]Mister Hood says his results show the work of genes in creating rice plants.
[02:23.52]He says scientists will have more than enough information to create a rice plant after they examine his work.
[02:33.57]Mister Hood says scientists could use the information to produce more rice and more nutritious 5 rice.
[02:43.42]And they could use the information to protect rice crops against insects and a lack of water.
[02:51.57]This could help feed more people.
[02:54.73]He also says the findings might lead to similar genetic mapping of other major crops, such as corn and wheat.
[03:04.37]Chinese scientists praised Monsanto for sharing the information.
[03:10.33]They said it will help them carry out their own research.
