THE TONOPLAST TRANSPORT SYSTEMS OF PLANT VACUOLES AND THEIR POTENTIAL APPLICATION IN BIOTECHNOLOGY

The pivotal role of plant vacuoles in plant survival was discussed in the review. Particularly, the providing of cellular turgor, accumulation of inorganic osmolytes and nutrients are the primary tasks of these cellular organelles. The main mechanisms of tonoplast transport systems were described. The known transport pathways of minerals, heavy metals, vitamins and other organic compounds were classified and outlined. The main systems of membrane vacuolar transport were reviewed. The outline of the physiological functions and features of vacuolar membrane transport proteins were performed. The physiological role of transport of minerals, nutrients and other compounds into vacuoles were discussed. This article reviews the main types of plant vacuoles and their functional role in plant cell. Current state and progress in vacuolar transport research was outlined. The examples of application for rinciples and mechanisms of vacuolar membrane transport in plant biotechnology were iven. The perspectives and approaches in plant and food biotechnology concerning transport and physiology of vacuoles are discussed
