"Salty" Rice Plant Boosts
Harvests British scientists are breeding a new
generation of rice plants that will be able to grow in soil containing salt
water. Their work may enable abandoned farms to become productive once
more. Tim Flowers and Tony Yeo, from Sussex University’s School
of Biological Sciences, have spent several years researching how crops, such as
rice, could be made to grow in water that has become salty. The
pair has recently begun a three-year programme, funded by the Biotechnology and
Biological Sciences Research Council, to establish which genes enable some
plants to survive salty conditions. The aim is to breed this capability into
crops, starting with rice. It is estimated that each year more
than 10m hectares (公顷) of agricultural land are lost becaus A. They are students at Sussex University. B. They are rice breeders. C. They are husband and wife. D. They are colleagues at an institution of higher learning.

[单项选择]"Salty" Rice Plant Boosts Harvests British scientists are breeding a new generation of rice plants that will be able to grow in soil containing salt water. Their work may enable abandoned farms to become productive once more.

The aim is to breed this capability into crops, starting with rice. It is estimated that each year more than 100 hectares (公顷) of agricultural land are lost because salt gets into the soil and stunts (妨碍生长) plants. The problem is caused by several factors.
