Title:FunctionalStudyofPteninJuvenileHormoneRegulatedReproductioninLocusts

Introduction:

Ininsects,juvenilehormone(JH)playsavitalroleinregulatingvariousphysiologicalprocesses,includingdevelopment,metamorphosis,andreproduction.TheAfricanmigratorylocust,Locustamigratoria,isamodelspeciesforstudyingtheJH-regulatedreproductiveprocessduetoitseasilyidentifiablereproductivephasesandwell-definedhormonalregulation.

Phosphataseandtensinhomolog(Pten)isknownforitsimportantrolesinregulatingvariouscellularprocesses,includingcellproliferation,survival,anddifferentiation.However,itsfunctioninJH-regulatedreproductioninlocustsremainstobeelucidated.

Objectives:

Theobjectivesofthisstudyareasfollows:

1.ToinvestigatetheexpressionpatternofPtenduringthereproductivephaseinthefemaleAfricanmigratorylocust.

2.TodeterminetheeffectofknockdownoroverexpressionofPtenontheJH-mediatedreproductiveprocessinthefemaleAfricanmigratorylocust.

3.ToinvestigatetheunderlyingmechanismsofPteninregulatingtheJH-mediatedreproductiveprocessinthefemaleAfricanmigratorylocust.

Methods:

1.RNAinterference(RNAi)willbeusedtoknockdownPtenexpressioninthefemaleAfricanmigratorylocust.Thereproductiveparameters,includingovariandevelopment,oocytematuration,andeggproduction,willbemonitoredandcomparedwiththecontrolgroup.

2.RecombinantbaculoviruswillbeusedtooverexpressPteninthefemaleAfricanmigratorylocust.Thereproductiveparameters,includingovariandevelopment,oocytematuration,andeggproduction,willbemonitoredandcomparedwiththecontrolgroup.

3.TheexpressionpatternsofPtenandJH-relatedgenes,includingJHbiosynthesisgenesandJHresponsegenes,willbemeasuredusingquantitativereal-timePCR.
