摘要： Rice is the staple food for most of the Chinese people. However, rice is a big water consumer as rice production uses 70% of the fresh water used in agriculture, which, in turn, consumes 80% of the total fresh water resources of China (Padolina, 1996). Because of water shortages, the likelihood of drought damage has become more and more serious. The annual economic loss from water shortages alone reaches more than US$25 billion in China (Deng, 1999). Developing drought tolerant (DT) or water saving rice cultivars is considered to be one of the most effective and economic approaches to ensuring China's food security (Luo and Zhang, 2001). Nevertheless, the drought tolerance of rice is extremely complex and little is known about its genetic mechanisms (Blum, 1999). To better understand the DT of plants and improving the DT of rice, several efforts have been made and some progress achieved in recent years under support mainly from The Rockefeller Foundation.
