In this study, we investigated the regulatory roles of the () gene in the reproductive process of female . Its total cDNA length was 1848 bp, encoding for 460 amino acids. It contained conserved domains typical of epoxide hydrolases, such as the Abhydrolase family domain, the EHN epoxide hydrolase superfamily domain, and the "WWG" and "HGWP" motifs. The qPCR results showed that the expression of was the highest in hepatopancreas. was expressed at all stages of the embryonic and larval stages. The expression of at different developmental periods of the ovary was positively correlated with ovarian maturation. In situ hybridization showed that it was mainly located in the cytoplasmic membrane and nucleus of oocytes. The RNA interference technique was used to study the role of in the process of ovarian maturation. The knockdown of with dsRNA in the experimental group resulted in a significant decrease in the percentage of ovaries exceeding stage O-III and the gonadal index compared with the control group. On day 14 (the second molt), the molt frequency was significantly higher in the control group than in the experimental group. The results showed that played an important role in ovarian maturation and molting.
在本研究中,我们调查了()基因在雌性(物种名称未给出)生殖过程中的调控作用。其cDNA全长1848 bp,编码460个氨基酸。它包含环氧化物水解酶典型的保守结构域,如Abhydrolase家族结构域、EHN环氧化物水解酶超家族结构域以及“WWG”和“HGWP”基序。qPCR结果表明,(基因名称未给出)在肝胰腺中的表达最高。(基因名称未给出)在胚胎和幼虫阶段的所有时期均有表达。卵巢不同发育时期(基因名称未给出)的表达与卵巢成熟呈正相关。原位杂交显示它主要位于卵母细胞的细胞质膜和细胞核中。采用RNA干扰技术研究(基因名称未给出)在卵巢成熟过程中的作用。与对照组相比,实验组用dsRNA敲低(基因名称未给出)后,超过O - III期的卵巢百分比和性腺指数显著降低。在第14天(第二次蜕皮),对照组的蜕皮频率显著高于实验组。结果表明,(基因名称未给出)在卵巢成熟和蜕皮中起重要作用。
