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.

答案
C
解析
