Gene expression profile of rice plants grown under natural field conditions based on microarray analysis of root samples at various growth stages encompassing the vegetative, reproductive and ripening stages. Samples were collected every 12:00 PM at weekly intervals during the 2008 cultivation season from 13 to 104 days after transplanting (DAT). A total of 14 samples (Sample list) 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.
