Global expression analysis of rice transcriptome datasets. A) Expression of the 57,302 probesets defined as the genome were classified as always expressed, never expressed, showing specific expression or non-specific expression based on MAS5.0 normalised microarray data. A probeset was considered to be expressed if it was called present in >/= 2 replicates in at least one sample. B) The proportion of rice transcripts that have Arabidopsis orthologues (determined by Inparanoid database v7.0) is indicated by the darker shade of colour for each subset. Significant (z-score, p < 0.01) enrichment/depletion of orthologues in each sub-set compared to the genome proportion is denoted with a red/blue ^, respectively. B) Analysis of FUNcational CATalogue (FUNCAT) was carried out on each set of genes. Subsets that were enriched or depleted in that FUNCAT compared to the genome are indicated by the red or blue asterisk respectively.
