Continuous gene expression profile of leaf at nighttime throughout the entire growth of rice in the field

ABSTRACT: A continuous gene expression profiling of leaves was performed during nighttime at regular interval from transplanting until harvesting to understand the changes of transcriptional program and physiological state throughout entire growth of the rice plant under natural field conditions. The uppermost fully-expanded leaf in the main stem corresponding to the 1st leaf until 83 days after transplanting (DAT) and the flag leaf from them on were sampled in two replicates at 12:00 midnight at 7- day intervals encompassing 17 different growth 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]

Comparison of gene expression profile of flag leaf from fertile and sterile lines of rice

Project description:To examine the role of formation of a strong sink during leaf senescence, we compared the expression profile of the flag leaf of three different sterile mutant lines with fertile plants. The fertile and sterile lines showed basically similar expression profiles of flag leaves sampled at the same time. However, the fertile lines showed more rapid and enhanced change in transcriptome as compared to the sterile lines indicating that leaf senescence initiated independent of sink formation and is accelerated by sink formation. Three independent mutant lines, namely, pair1, pair2, and mel1-1, and fertile plants (homozygous or heterozygous) derived from each segregating population were used for comparison. The flag leaves were sampled at initiation of heading, 1 week after heading (WAH), 2 WAH, and 3 WAH, with three biological replicates.
