List of 2x-ESTs that show at least two-fold differential expression by microarray analysis. A total of 335 2x-ESTs were identified by microarray analysis that showed at least a two-fold difference in modulation as compared to leaf. These 2x-ESTs were compared to similar sequences in the Entrez database by blastx analysis and the strongest known homology was identified. This figure shows the upper quartile, for the full image please see Additional File 1. The 2x-ESTs induced at least two-fold were highlighted in red whereas 2x-ESTs repressed at least two-fold were highlighted in green. Microarray-determined fold-change is shown for each 2x-EST for green, pink, and red flesh as compared to leaf.
