Using semi-quantitative RT-PCR, the differential expression profiles of eleven selected genes were confirmed in the ovaries of triploid and diploid. These genes fell in gene categories with a wide range of functions. The results indicated that triploidy affects the dynamic gene regulatory network in triploid ovary. This study established a firm basis for future investigation on characterization of crucial molecular events for normal ovarian development in shrimp.To further dissect exact gene functions for gonad development of shrimp, three differentially expressed genes between diploid and triploid ovary, PCNA (proliferating cell nuclear antigen), CAS/CSE1 (cellular apoptosis susceptibility protein/chromosome segregation 1) and SSRF (spermatogonial stem-cell renewal factor) were characterized on certain aspects.

利用抑制性消减杂交技术，建立了对虾二倍体和三倍体卵巢间的2个消减文库；在正向消减文库(以三倍体卵巢作为实验组，二倍体卵巢作为驱动组)中，鉴定到54个基因；在反向消减文库(以二倍体卵巢为实验组，三倍体卵巢为驱动组)中，鉴定到16个基因；选取11个差异表达的基因，利用半定量RT-PCR的方法对其在二倍体和三倍体卵巢间的表达进行了检测，均能很好地与消减结果相吻合；这些差异基因编码多种功能的蛋白，分析表明染色体的三倍化使三倍体卵巢中的基因调控网络受到了影响；为深入揭示维持卵巢正常发育的关键分子调控事件奠定了基础。
