Journal Article
Gender-specific function of melatonin receptor (MTRI) in gonads of red swamp crayfish, Procambarus clarkii
2025
Overview
Melatonin receptor (MTR) plays a crucial role in mediating melatonin signaling. Therefore, it is necessary to study functions and characteristics of MTR. In this study, full length cDNA of
MTRI
in
Procambarus clarkii
was cloned. The phylogenetic tree revealed that MTRI amino acid sequence of
P. clarkii
had the closest relationship with
Homarus americanus
. The temporal and spatial distribution expression results indicated that
MTRI
was highly expressed in gonadal tissues and eyestalk. RNA interference (RNAi) was used to identify the content of related hormones and the relative expression of genes in gonads of
P. clarkii
. The results showed that melatonin had an important effect on gonad of
P. clarkii
. Due to the specificity of the reproductive system in female and male crayfish, the siRNA interference efficiency was different, GIH, GTH, 5-HT and MT showed the opposite trend. Levels decreased in females but increased in males. However, the sex hormones E2 and T decreased, indicating that the silencing of MTRI will hinder gonadal development. This study provides a theoretical basis for further study of the role of melatonin in crustacean gonads.
