The amount of seeds they produced was close to normal. In addition, the researchers found that the plants could【S7】______on only thirty percent of the normal amount of【S8】______water. Yield loss was minor, they said.
The【S9】______appeared late last year in the Proceedings of the National Academy of Sciences. The University of California has applied for patent【S10】______for the technology. The researchers expect to move forward with field testing of the transgenic tobacco in late August. They hope for similar results with crops like tomatoes, rice, wheat and cotton.

答案
C
解析
