Identification of <i>C</i>. <i>elegans</i> serotonin receptor homologues in <i>Globodera</i> spp.

Globodera pallida and G. rostochiensis homologues of the five C. elegans genes encoding serotonin receptors were identified by reciprocal best BLAST hit analysis of the G. pallida [4] and G. rostochiensis [3] predicted gene complements.* All are G-protein coupled receptors with the exception of MOD-1 which is a serotonin-gated chloride channel. The likely gpa-ser-1 orthologue is incomplete in the genome assembly and encompassed by two adjacent gene models; this was confirmed by analysis of a transcriptome assembly produced using existing J2 RNAseq data [4]. # The complete sequence for gpa-ser-5 was not present in the genome assembly, but was identified from the transcriptome assembly.
