Normalized expression values are given for the F2 line and values for each mutant are expressed as ratios of signal intensity compared to normal plants. Genes were considered to be significantly differentially expressed when expression ratio values were lower than 0.5 or higher than 2.0. Values between the two thresholds are indicated in italics.
