Diurnal and circadian gene expression profile of root throughout the entire growth of rice in the field


ABSTRACT: A continuous gene expression profiling of roots was performed at regular interval during a 48-hr period in 2 different growth stages to characterize the diurnal and circadian gene expression profile of rice growth under natural field conditions. Root was collected at 2-hr intervals during a 48-hr period at 2 different growth stages corresponding to early and late vegetative stages. 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]
