Gene's past could improve the future of rice
Date:1/23/2009

tics, genes responsible for those traits disappeared.

"Humans knew that if the seeds stayed on the plant, or it had a higher yield, they could save some of the seeds to plant next year," Jackson said. "That was unintentional breeding."

Those favorable genes are still around in wild rice species because they were valuable for plants in other climates or situations, he said.

Jackson was involved with earlier research that looked at cell structure in rice and also is studying the gene responsible for flowering in rice plants. Once those genes are better understood, scientists can match the best genes for particular climates to give growers better yields.

One example can be found in a variety of rice that has genes making it drought-resistant. Scientists could breed those genes into domesticated rice in Africa where water shortages can devastate crops.
