Trehalose is a non-reducing disaccharide in which two glucose units are linked by an α, α-1, 1-glycosidic linkage. Trehalose is widely distributed in nature. In bacteria, fungi, insects and invertebrates, trehalose functions as a storage carbohydrate or a blood sugar. In addition, trehalose can protect cellular integrity against a variety of environmental stresses associated with desiccation, heat, and cold. Within the past 10 years, it has become clear that higher plants can also synthesis trehalose although the level is fairly low. Recent studies have suggested that trehalose biosynthesis is involved in the regulation of plant development, sugar metabolism and ABA signal transduction. In this study, to address the function of trehalose in plant cells, we have utilized a microarray to screen trehalose-induced genes in rice.
