To investigate the tomato transcriptome dynamics of fruit set, RNA were isolated from flower buds (Bud) and flowers at anthesis (Ant) and post-anthesis (Pos) stages. For each stage, cDNA libraries were generated from three biological replicates and subjected to Illumina mRNA-Seq technology sequencing. Then, after mapping reads to the tomato genome sequence, we obtained a table of raw counts with 34675 rows (genes) and 9 columns (3 stages and 3 replicates per stage). These technical procedures are described in Maza et al. (2013 (link)). In this paper, for sake of simplicity, the matrix (34675 × 9) containing raw counts is denoted by X.
