The African migratory locust, Locusta migratoria, is a model species for studying the JH-regulated reproductive process due to its easily identifiable reproductive phases and well-defined hormonal regulation.Phosphatase and tensin homolog (Pten) is known for its important roles in regulating various cellular processes, including cell proliferation, survival, and differentiation. However, its function in JH-regulated reproduction in locusts remains to be elucidated.Objectives:The objectives of this study are as follows:1. To investigate the expression pattern of Pten during the reproductive phase in the female African migratory locust.2. To determine the effect of knockdown or overexpression of Pten on the JH-mediated reproductive process in the female African migratory locust.3. To investigate the underlying mechanisms of Pten in regulating the JH-mediated reproductive process in the female African migratory locust.Methods:1. RNA interference (RNAi) will be used to knockdown Pten expression in the female African migratory locust. The reproductive parameters, including ovarian development, oocyte maturation, and egg production, will be monitored and compared with the control group.2. Recombinant baculovirus will be used to overexpress Pten in the female African migratory locust. The reproductive 精品文档---下载后可任意编辑parameters, including ovarian development, oocyte maturation, and egg production, will be monitored and compared with the control group.3. The expression patterns of Pten and JH-related genes, including JH biosynthesis genes and JH response genes, will be measured using quantitative real-time PCR.4. Western blotting analysis will be used to investigate the signaling pathways involved in the Pten-regulated JH-mediated reproductive process.Expected Outcomes:1. The expression pattern of Pten during the reproductive phase in the female African migratory locust will be identified.2. The knockdown or overexpression of Pten will affect the reproductive parameters, indicating the involvement of Pten in the JH-regulated reproductive process.3. The underlying mechanisms of Pten in regulating the JH-mediated reproductive process in the female African migratory locust will be elucidated.Conclusion:This study will provide a better understanding of the roles of Pten in the JH-mediated reproductive process in the female African migratory locust and may provide insights into insect reproductive regulation in general.
