Fold ratios are indicated for genes showing quantitative changes in expression. For genes with detected expression only in DpDf or wild-type plants, the direction of the change is indicated. A gene was defined as turned on when its transcript was absent in a wild-type tissue and present in an aneuploid tissue. Similarly, a gene was defined as turned off when its transcript was present in a wild-type tissue and absent in an aneuploid tissue.
Statistically insignificant changes in gene expression (t test, P > 0.5) are indicated in italics.
NE, Not expressed. Expression of the gene is not detected in both DpDf and wild-type plants in a particular tissue.
