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.
