Has an Inhibitory Effect on Ovarian Reproduction in .

is an exoribonuclease that degrades mRNA in the cytoplasm along the 5'-3' direction. A previous study indicated that it may be involved in the reproduction of . Quantitative real-time PCR was used to detect the spatiotemporal expression pattern of . At the tissue level, was significantly expressed in the ovary. During development, was significantly expressed at the CS stage of the embryo, on the 10th day post-larval and in the O2 stage of ovarian reproduction. The in situ hybridization results showed the location of in the ovary. The expression of was significantly increased after in vivo injection of dsRNA. This suggests that negatively regulates the expression of . Furthermore, we counted the number of at various stages of ovarian reproduction on different days after RNAi. The results showed that ovarian development was significantly accelerated. In general, the results of the present study indicate that has an inhibitory effect on the ovarian maturation of . The inhibitory effect might be through negative regulation of .
