Castor seeds are energy reserves of superior quality whose molecular transformations play a vital role in seed development and germination.They are compartmentalized in specialized sub-cellular systems encapsulated by membranes.Membrane re-modeling is a fundamental phenomenon demanded to regulate the functional activities,mass exchange etc of its interior components.Therefore an understanding of molecular factors constituting the membrane would yield us a transparent picture of the seed molecular transformations triggered by cues.

Researchers from USA have isolated membranes from castor seed protein bodies thought to play a key role in protein utilization for seed development.They followed a differential extraction method for the selective isolation of vacuolar membrane and purified it with advanced centrifugation techniques.A protein fingerprint was generated ultimately which revealed unique proteins whose functional activities are yet to characterized.Lipids chemistry proved to be complex but showed typical members.

Characterization of novel proteins is an exciting field and this research paper lays an authentic platform to make in-depth studies.
