Differential expression of X-box binding protein 1 during ovarian development and association between its SNP and growth-related parameters of the giant tiger shrimp Penaeus monodon

To assess the possible biological roles of X-box binding protein 1 in reproduction and growth of P. monodon, the PmXbp1 cDNA sequence was characterized. Expression patterns of PmXbp1 during ovarian development in wild P. monodon broodstock were examined. Effects of eyestalk ablation (wild broodstock) and serotonin induction (domesticated broodstock) on expression levels of ovarian PmXbp1 were examined. In addition, analysis of relationships between SNP detected by SSCP and DNA sequencing and expression levels of PmXbp1, and growth traits in juvenile shrimp was examined.
