Gonadal transcriptome analysis reveals MAG participates in ovarian suppression of intersex red claw crayfish (Cherax quadricarinatus).

ABSTRACT:

Background

The red claw crayfish (Cherax quadricarinatus) is a commercially and ecologically significant species that displays a unique intersex model with an ovotestis gonad and was identified to have functional testes and a vestigial ovary, which was inhibited by insulin-like androgenic gland hormone (IAG), but the underlying molecular mechanisms are still unclear.

Results

In this study, the structure and transcriptomic profiles of ovotestis and female and male gonad was analysis and compared, 406 differentially expressed genes were identified, among which membrane-anchored AG-specific factor (MAG) exhibited significantly greater expression in ovotestis gonads than in male or female gonads. The localization of MAG in type I or II cells of androgenic gland revealed its pote
