“…This transcriptome analysis found that the vitellogenin receptor (Vtgr) gene up-regulated significantly higher in the vitellogenic stage of the ovary’s development than in the non-vitellogenic stage, further evidence supporting this gene’s involvement in ovarian maturation. Earlier research, reporting a significantly higher expression level of Vtgr in broodstock at the late stage of ovarian development of P. monodon than in juveniles, revealed the involvement of this gene in oogenesis [ 32 ]. Another important gene in shrimp reproduction is progestin membrane receptor component 1 (Pgmrc1) which was recently reported to stimulate ovarian maturation.…”

The banana shrimp (Fenneropenaeus merguiensis) is one of the most commercially important penaeid species in the world. Its numbers are declining in the wild, leading to a loss of broodstock for farmers of the shrimp and a need for more successful breeding programs. However, the molecular mechanism of the genes involved in this shrimp’s ovarian maturation is still unclear. Consequently, we compared transcriptomic profiles of ovarian tissue from females in both the vitellogenic stage and the non-vitellogenic stage. Using RNA-Seq technology to prepare the transcriptome libraries, a total of 12,187,412 and 11,694,326 sequencing reads were acquired from the non-vitellogenic and vitellogenic stages respectively. The analysis of the differentially expressed genes identified 1,025 which were significantly differentially expressed between the two stages, of which 694 were up-regulated and 331 down-regulated. Four genes putatively involved in the ovarian maturation pathway were chosen for validation by quantitative real-time PCR (RT-qPCR). The data from this study provided information about gene expression in ovarian tissue of the banana shrimp which could be useful for a better understanding of the regulation of this species’ reproductive cycle.

“…Vitellogenesis is a critical part in the gonad maturity process. During the late vitellogenesis process, the vitellogenin receptor mediates the uptake of vitellogenin into the oocytes from the hemolymph when oocytes develop into OS3 in GS3 [ 57 – 59 ], resulting an increased expression of VgR among crustacean and insect species [ 60 – 62 ]. The VgR expression showed an earlier response to food supply than did the occurrence of GS3 gonads on Day 9 in Groups 9F and 18F ( Fig 7 ).…”

Effects of Elevated Temperature and Food Supply on the Termination of Over-Summering and Subsequent Development of the Calanoid Copepod Calanus sinicus: Morphology, Physiology and Gene Expression

The copepod Calanus sinicus Brodsky dominates the zooplankton in the Yellow Sea, China, and undergoes over-summering within the Yellow Sea Cold Water Mass (YSCWM). Termination of over-summering and subsequent development are regarded as key processes in population recruitment, and are probably linked to environmental variations in the YSCWM. In this study, we examined the effects of temperature (9 and 18°C) and food conditions (0.1 μg C mL-1 and unfed) on metabolic rates, morphological characteristics, and relative gene expressions of six genes involved in molting, gonad development, lipid catabolism, and stress tolerance processes of C. sinicus during termination of over-summering and subsequent development. Both elevated temperature and external food supply rapidly ended over-summering of C. sinicus, accompanied by up-regulation of the ecdysteroid receptor (EcR) gene expression and increased metabolic rates. These environmental conditions resulted in irreversible termination of over-summering and ensure the success of molting. During subsequent development, the lipid reserve in oil sacs could permit only early gonad development. The food supply might be a trigger to activate the final maturity of gonad by up-regulating expression of the vitellogenin receptor (VgR) gene. Thus, food played an indispensable role in population recruitment after termination of over-summering, whereas the elevated temperature accelerated these physiological processes. This study revealed the first dynamic profiles of physiological processes involved in over-summering termination and the subsequent development of C. sinicus using morphological, physiological and molecular methods simultaneously, confirmed the quiescent state of over-summering C5 copepodites, detected the effects of environmental changes on over-summering termination and subsequent development, and provided a foundation for future investigations of the mechanisms involved in over-summering in YSCWM.

Klinbunga et al (2015) identified SNPs in the vitellogenin receptor (PmVtgr) gene segment of 14-month-old P. monodon (N = 64) by SSCP analysis. Significant relationships between different SSCP patterns of PmVtgr and GSI and ovarian weight of P. monodon were found.…”
