Gene expression profile of rice plants grown under natural field conditions based on microarray analysis of root samples. Root samples were collected in a 48-hr period at 2-hr intervals at 2 different growth stages during the 2008 cultivation season. A total of 50 samples (Sample list) were used for hybridization using the Agilent one-color (Cy3) microarray-based gene analysis system. The expression profile for each gene is shown as raw data representing Cy3 signal intensity and normalized data (log2). Search options include keyword search for individual RAP locus ID and accession number, or chromosome search to get a list of all genes for each chromosome.
