Table 2. Number of predicted IRs and iGluRs in transcriptomes from four species of decapod crustaceans.
| Species | iGluRs | IRs | |||
|---|---|---|---|---|---|
| Co-receptor | Tuning IRs | ||||
| Conserved | Species-Specific | Total | |||
| Panulirus argus | 10 | 4 | 85 | 169 | 254 |
| Homarus americanus | 11 | 4 | 128 | 53 | 181 |
| Procambarus clarkii | 9 | 4 | 73 | 19 | 92 |

Conservative estimate of number of IRs and iGluRs expressed in the transcriptomes of the four decapod crustaceans. iGluRs include NMDA and non-NMDA receptor sequences. Co-receptor IRs are IR25a, IR8a, IR76b, and IR93a. Conserved tuning IRs are variant tuning IR sequences that have homologues in other species. Most sequences accounted here have both domain regions representative of iGluRs and IRs. Some incomplete sequences that are homologous to conserved IRs in another species are also included (S10–S12 Files).
* indicates transcriptome generated from LF and dactyls only, while transcriptomes from the other species also include reads from brain tissue.
