Leaf gene expression profile of rice during sunrise


ABSTRACT: A continuous gene expression profiling of leaves was performed at regular interval during the sunrise period to understand the changes of transcriptional program in the rice plant grown under natural field conditions in response to solar radiation. At 79 days after transplanting, leaf samples corresponding to the uppermost fully expanded leaves were collected at 10-min intervals in two replicates from 3:50 AM until 6:00 AM. All samples were obtained from rice plants grown in the field during the 2008 cultivation season.

Similarity of gene expression across a wide range of biological conditions can be efficiently used in characterization of gene function. We have constructed a rice gene coexpression database, RiceFREND (http://ricefrend.dna.affrc.go.jp/), to identify gene modules with similar expression profiles and provide a platform for more accurate prediction of gene functions. Coexpression analysis of 27 201 genes was performed against 815 microarray data derived from expression profiling of various organs  ...[more]
