The emphasis is placed on roles of vacuoles played in the temporary storage of saccharides and organic acids, in the accumulation of water soluble products of secondary metabolism and in the intracellular digestion of protein.
Gas vesicles, also known as gas vacuoles, are nanocompartments which are freely permeable to gas, and occur mainly in Cyanobacteria, but are also found in other bacteria species and some archaea. Gas vesicles allow the bacteria to control their buoyancy. They are formed when small biconical structures grow to form spindles. The vesicle walls are composed of a hydrophobic gas vesicl… WebMar 29, 2024 · Within the physiologically relevant pH range (5.5–7.5), the buffering capacity of the cell sap varies between 6 and 15 mmol Eq(H +)/L cell sap/pH unit (Figure S2(b)). …

Error bars show sd of n = 3 biological replicates. (E) Vacuolar pH in root epidermal cells is not changed upon AVP1 overexpression. Vacuolar pH was measured in roots of 6-d-old plants. Error bars represent sd of n = 3 biological replicates.
WebAfter chelation, trace metals in roots may be stored in the vacuole and/or cell wall or exported to the shoot via the xylem. The vacuole is generally considered to be the main storage site for trace metals in plant cells and vacuolar compartmentalization of trace metals is also a part of the tolerance mechanism (Guo et al., 2012).
