Sex Change in Clownfish: Molecular Insights from Transcriptome Analysis

Abstract: Sequential hermaphroditism is a unique reproductive strategy among teleosts that is displayed mainly in fish species living in the coral reef environment. The reproductive biology of hermaphrodites has long been intriguing; however, very little is known about the molecular pathways underlying their sex change. Here, we provide the first de novo transcriptome analyses of a hermaphrodite teleost´s undergoing sex change in its natural environment. Our study has examined relative gene expression across multiple gr… Show more

“…Particularly interesting is that environmental triggers of HSPs extend beyond temperature. Some members of the HSP family show differential expression during socially induced sex change in the two‐banded anemonefish ( Amphiprion bicinctus ) (Casas et al ., ), and HSP10 is associated with female to male sex reversal (the trigger of sex reversal is not yet known) in the rice field eel ( Monopterus albus ), where it plays a role in inhibiting apoptosis in male germ cells (He et al ., ). Given HSPs demonstrated roles in sex determination across ESD taxa, and responsiveness to diverse environmental stimuli, they are promising candidates for further study (Fig.…”

“…In sum, the clownfishes of the genus Amphiprion present a wonderful opportunity to investigate the proximate and ultimate causes of coloration in coral reef fishes. This opportunity is enhanced by the recent development of transcriptomic (Amphiprion bicinctus, Casas et al, 2016) and genomic (Amphiprion frenatus, Marcionetti et al, 2018; Amphiprion ocellaris, Tan et al, 2018) resources for the genus. Here, we used a combination of RNA sequencing, transcriptome annotation, differential gene expression analyses and gene ontology enrichment analyses to (i) generate a de novo transcriptome for A. percula, (ii) identify over-represented genes associated with orange, white, and black epidermal tissues, and (iii) identify potential functions of those genes in A. percula.…”
