Abstract:
Wheatembryogenicnon-regenerativecellsholdgreatpotentialforplanttissuecultureandcropimprovement.Understandingtheircellularcomposition,specificallytheprofileoffreeaminoacids,iscrucialforoptimizingthetissuecultureconditionsandenhancingtheregenerationabilityofembryogeniccells.Inthisstudy,weperformedananalysisoffreeaminoacidsinwheatembryogenicnon-regenerativecellsanddiscusstheirbiologicalsignificance.
1.Introduction:
Wheatembryogenicnon-regenerativecellsarecapableofformingembryogeniccallusbutfailtoregenerateintoplantlets.Theunderlyingreasonsfortheinabilitytoregeneratearemultifaceted,andmetabolicalterationsaresuggestedtoplayacrucialrole.Aminoacidsarekeymetabolitesinvolvedinvariouscellularprocesses,includingproteinsynthesis,stressresponse,andhormonesignaling.Thus,analyzingthefreeaminoacidprofilecanprovideinsightsintothephysiologicalandmolecularmechanismsunderlyingtheregenerativeabilityofwheatembryogeniccells.
2.Methods:
2.1SamplePreparation:Wheatembryogenicnon-regenerativecellswereculturedonasuitablemedium,andafterreachingthedesiredgrowthstage,cellswereharvested,frozen,andlyophilized.Thelyophilizedcellswerepulverizedtoafinepowderforfurtheranalysis.
2.2AminoAcidExtraction:Thepulverizedcellswereextractedusinganappropriatesolvent,suchas80%coldmethanol,toobtainasamplecontainingfreeaminoacids.
