Sampling Daphnia's expressed genes: preservation, expansion and invention of crustacean genes with reference to insect genomes

Table 3

Response to metals	Up in males	Up in females	No change between sexes	Total
Responsive to cadmium and/or arsenic	45% (85/188)	42% (25/59)	49% (47/96)	46% (157/343)
No change in both metals	48% (95/197)	12% (13/112)	33% (44/135)	34% (152/444)
Total	47% (180/385)	22% (38/171)	39% (91/231)	39% (309/787)

The percentage of Daphnia pulex assembled EST sequences with no matches to insect proteins, partitioned by their differential expression patterns in experiments designed to detect transcriptional differences between the sexes (Eads et al. submitted) and genes responding to toxic metal exposure to cadmium and arsenic (Shaw et al. submitted, and in prep). A 5% false discovery rate is applied to all three experimental results. The number of orphan genes over the total number of genes within the partition is indicated in parentheses.
