CAS Researchers Clone Heat Tolerance Gene from African Rice Variety
May 27, 2015| |
A team of scientists from the Chinese Academy of Sciences led by Lin Hongxuan successfully isolated and cloned heat tolerance genes from African rice strains, which could be used to develop rice varieties that can resist the effects of global warming.
According to Lin, temperatures over 35 degrees Celsius decreased the productivity of rice plants. Heat stress destroys rice proteins, causing the plants to wither. Under heat stress, the heat tolerance gene from African rice variety is activated, and gets rid of the toxic proteins that may cause death to the rice plant. The researchers have tested Asian rice varieties with the transplanted gene in field conditions. The results showed that the gene's dominant traits enabled the transformed plants to withstand heat stress. Furthermore, Lin said that the cloned gene may also be used to develop heat tolerant varieties of wheat and cruciferous vegetables such as Chinese cabbage.
