AI Article Synopsis
- - The study investigates the genetic differences related to spawning abilities in Pacific white shrimp (Penaeus vannamei) by analyzing structural variations (SVs) in shrimp with high and low fertility.
- - Researchers identified 2,323 SV events in high fertility (HF) shrimp and 1,859 in low fertility (LF) shrimp, linking these variations to specific genes that play a role in reproduction.
- - The findings suggest that certain genes, such as Cttn and Lhcgr, may be key to enhancing fertility in shrimp, providing a foundation for future research and targeted breeding strategies.
Article Abstract
Background: The genetic basis underlying spawning abilities in the Pacific white shrimp, Penaeus vannamei, remains largely unexplored. To investigate genetic variations potentially related to reproductive performance, a systematic bioinformatic analysis was conducted to identify structural variations (SVs) with different polymorphic spectra in P. vannamei with high fertility (HF) and low fertility (LF).
Results: A total of 2,323 and 1,859 SV events were identified exclusively in the HF and LF groups, respectively. These SVs were mapped to 277 genes in the HF group and 231 genes in the LF group. Gene Ontology (GO) enrichment analysis based on SNPs (single nucleotide polymorphism) and SVs revealed several neural-related processes, suggesting the importance of neural regulation in reproduction. Notably, we identified a set of promising genes, including Cttn, Spast, Ppp4c, Spire1, Lhcgr, and Ftz-f1, which may enhance fertility in shrimp.
Conclusion: In conclusion, this study is the first to establish a link between SVs and reproductive traits in P. vannamei. The promising genes discovered have the potential to serve as crucial markers for enhancing reproductive traits through targeted genotyping.
