Microarray analysis of gene expression under different light conditions

ABSTRACT: The size of tomato fruits are largely dependent on growth conditions. To obtain insights on how light intensity contributes to translocation from a leaf and a fruit, we developed a plant irradiation system based on light-emitting diodes (LEDs) to a leaf. By using this system, we investigated the changes of transcript profiles of tomato leaves and fruits grown under different light conditions. 20 samples were analyzed (14 leaf samples and 6 pericarp samples); 2-3 biological replicates were used.

Gene-to-gene coexpression analysis provides fundamental information and is a promising approach for predicting unknown gene functions in plants. We investigated various associations in the gene expression of tomato (Solanum lycopersicum) to predict unknown gene functions in an unbiased manner. We obtained more than 300 microarrays from publicly available databases and our own hybridizations, and here, we present tomato coexpression networks and coexpression modules. The topological characteristi  ...[more]
