Known transcripts differentially expressed in response to overexpression of otd, grouped according to functional classes. Bars represent the fold change between differentially expressed transcripts in heat-shocked wild-type embryos and heat-shocked otd embryos. Positive values indicate that the relative expression level of a gene is increased (upregulated) following otd overexpression and negative values indicate a decrease (downregulated). Absolute average difference (Avg Diff) values are given for the otd overexpression condition as follows: white bars, Avg Diff < 100; gray bars, Avg Diff from 100-1,000; black bars, Avg Diff > 1,000.
