 This study used genome-wide gene expression profiling to analyze the response of rice to drought stress at different development stages and tissues. The results showed that most of the differentially expressed genes were tissue or stage-specific with distinct function categories in each tissue. Additionally, several genes were regulated in a reciprocal way in two tissues at the same development stage. A CIS element containing a special CGCG box was identified to over present in the upstream of 55 common induced genes, which may be important for rice plants responding to drought environment. The study provides valuable information for the improvement of drought tolerance in rice by identifying differentially regulated genes and unique candidates CIS elements.
