摘 要：正Plant cells possess multifunctional vacuolar compartments that are of central importance to plant development.Recent studies have demonstrated that the lytic and storage functions of vacuoles reside in separate vacuolar compartments.However,little is know about the origins of these compartments.In this study,we have examined the ultrastructure of high pressure frozen/freeze-substituted tobacco root tip cells from germinating seedlings.Our micrographs show that during germination,the changes in protein storage
