Nov 16, 2006 · In this review it will be shown how vacuolar transporters are an integrated part of a complex cellular network, enabling the plant to react properly to changing environmental conditions, store nutrients and energy in time of plentiful supply, and maintain optimal metabolic conditions in the cytosol.

As in animal and yeast cells, the vacuolar transport pathway in plants begins with the endoplasmic reticulum (ER) (Figure 1). A conventional route of vacuole transport consists of a vesicle transport pathway including endoplasmic reticulum output mediated …

Biochemical and electrophysiological studies on plant vacuolar transporters became feasible in the late 1970s and early 1980s, when methods to isolate large quantities of intact vacuoles and purified vacuolar membrane vesicles were established.

It is clear that vacuolar transporters are an integrated part of a complex cellular network that enables a plant to react properly to changing environmental conditions, to save nutrients and energy in times of plenty, and to maintain optimal metabolic conditions in the cytosol.

Jun 16, 2021 · Tonoplast proteins are involved in intracellular ion transport, pH regulation, and vacuole transport pathways. Studies on vacuole initiation have focused on the dynamics of the vacuole cavity and the transport and re-localization of vacuole-related proteins.

Jan 1, 2013 · In this review, we describe different transport mechanisms leading to vacuolar accumulation of substances. Then, we summarize vacuolar transport by categorizing substances into inorganic ions, primary metabolites, secondary metabolites, and xenobiotics, in addition to their physiological functions.

May 19, 2015 · Vacuolar sugar transporters helped to identify target mechanisms allowing to direct membrane proteins to the tonoplast. The ability of higher plants to store sugars is of crucial importance for plant development, adaption to endogenous or environmental cues and for the economic value of crop species.

Jan 9, 2019 · Glycerol 3-phosphate transporter types have now been identified as tonoplast-localized vacuolar Pi efflux transporters, integrating vacuolar Pi transport systems in plants. Phosphorus is an...

In this review, we provide an updated inventory of vacuolar transport mechanisms and a comprehensive summary of their physiological functions. Keywords: Channel; Ion; Primary metabolite; Secondary metabolite; Transporter; Vacuole; Vesicle transport; Xenobiotic.

Oct 2, 2020 · Here we analyse the molecular mechanisms connecting and modulating the transport processes at both the plasma and the vacuolar membranes of guard cells. II. III. IV. VI. The vacuole occupies the major part of the cellular volume, up to 90% in differentiated plant cells (Krüger & Schumacher, 2018).
