Abstract
In plants, sucrose is the major transport form for photoassimilated carbon and is both a source of carbon skeletons and energy for plant organs unable to perform photosynthesis (sink organs). As a molecule translocated over distance, sucrose has to pass through a number of membranes. Membrane transport of sucrose has therefore been considered for a long time as a major determinant of plant productivity. After several decades of physiological and biochemical experiments measuring the activity of sucrose carriers, unequivocal evidence came from the first identification of a cDNA coding a sucrose carrier (SoSUT1, Riesmeier et al. (1992) EMBO J. 11, 4705-4713). At present 20 different cDNAs encoding sucrose carriers have been identified in different plant species, in both dicots and monocots (one case). The total number is increasing rapidly and most importantly, it can be guessed from the results obtained for Arabidopsis, that in each species, sucrose transporters represent a gene family. The sequences are highly conserved and those carriers display the typical 12 transmembrane alpha-helices of members of the Major Facilitator superfamily. Yeast expression of those carriers indicate that they are all influx carriers, all cotransport sucrose and proton and that their affinity for sucrose is surprisingly similar (0.2-2 mM). All their characteristics are in agreement with those demonstrated at the physiological level in plants. These characteristics are discussed in relation to the function in plants and the few data available on the structure of those transporters in relation to their function are presented.

Abstract
The protein phosphatase inhibitor okadaic acid (OA) either provided directly to sugar beet (Beta vulgaris L.) leaf discs or infiltrated in the leaf blade rapidly inhibited sucrose uptake. Methyl okadaic acid, a biologically inactive analogue of OA, had only a marginal effect on uptake. OA inhibited proton-motive force-driven uptake of sucrose into plasma membrane vesicles, without affecting their proton permeability. OA did not significantly affect the amount of sucrose transporters present in the vesicles, as estimated by ELISA with specific antibodies. It is concluded that OA directly inhibits the activity of a H+-sucrose cotransporter of the plant plasma membrane, likely by maintaining it in a phosphorylated form.

Abstract
The activity and the expression of sucrose, hexose and amino acid transporters were studied with fresh, cut or aged tissues and plasma membrane vesicles (PMV) of mature sugar beet (Beta vulgaris L.) leaves. Cutting and ageing both induced an increase of the transcripts coding for sucrose transporters and hexose transporters. No significant effect could be detected on the amino acid transporter transcripts with the probe used (aap1). A polyclonal serum directed against the Arabidopsis thaliana sucrose transporter (AtSUC1) reacted with a 42 kDa band of the sugar beet PMV, confirming previous biochemical identification of this band as a sucrose transporter. ELISA assays run with microsomal fractions and PMV using the AtSUC1 sucrose transporter probe indicated that ageing, and to a lesser extent cutting, increased the amount of sucrose transporter present in the plasma membrane. However, while cutting strongly stimulated proton-motive force driven uptake of sucrose in PMV, ageing only resulted in a slight stimulation. These data give evidence for transcriptional, post-transcriptional and post-translational controls of the activity of the sucrose transporter by mechanical treatments. Proton-motive force driven uptake of 3-O-methylglucose and valine in PMV was strongly stimulated in PMV from aged tissues, although previous data had shown that cutting did not affect theses processes. Therefore, the plant cells possess various levels of control mechanisms that allow them to regulate fluxes of the main assimilates across the plasma membrane when their natural environment is directly or indirectly altered.

Abstract
The fluxes of carbohydrates across the plasma membranes of higher-plant cells are catalysed mainly by monosaccharide and disaccharide-H+ symporters. cDNAs encoding these different transporters have been cloned recently and the functions and properties of the encoded proteins have been studied extensively in heterologous expression systems. Several of the proteins have been identified biochemically in these expression systems and their location in plants has been shown immunohistochemically or with transgenic plants which were transformed with reporter genes, expressed under the control of the promoters of individual transporter genes. In this paper we summarize the current knowledge on the molecular biology and biochemistry of higher-plant sugar transport proteins.

Abstract
Purified plasma membranes from sugar beet leaves were solubilized by 1% 3-((3-cholamidopropyl)dimethylammonio)-1-propanesulfonate and loaded on a sepharose 6 B column substituted with sucrose. Elution with sucrose at pH 5.2 yielded a peak that represented 0.2% of the loaded protein. This peak did not appear when the samples were pretreated with either 0.5 mM N-ethylmaleimide (NEM) or 0.5 mM para-chloromercuribenzenesulfonic acid. It was also absent when palatinose, a sucrose analogue not recognized by the sucrose transporter, was used as the affinity ligand. The peak specifically eluted by sucrose from the sucrose-Sepharose column exhibited sucrose transport activity after reconstitution into proteoliposomes. This peak was further fractionated by ion-exchange chromatography on a Mono-Q column, and the different fractions obtained were differentially labeled by [3H]NEM in the presence of sugars recognized (sucrose, maltose) or not recognized (palatinose) by the sucrose transporter. The data allowed to identify two fractions that were enriched with two polypeptides (56 and 41 kDa) differentially labeled by NEM in the presence of sucrose.

Abstract
The heterotrophic tissues of the plant are dependent upon carbon and nitrogen import for normal growth and development. In general, oxidized forms of these essential elements are reductively assimilated in the leaf and, subsequently, sucrose and amino acids are transported to the heterotrophic cells in a process known as assimilate partitioning. In many plant species, a critical component of the assimilate partitioning pathway is the proton-sucrose symport. This active transport system couples sucrose translocation across the plasma membrane to the proton motive force generated by the H(+)-pumping ATPase. To date, the proton-sucrose symport is the only known system that can account for sucrose accumulation in the vascular tissue of the plant. This review focuses on recent advances describing the transport properties and bioenergetics of the proton-sucrose symport.

Abstract
The proteins from plasma membranes from sugar beet leaves were solubilized by 1% CHAPS and separated by size exclusion chromatography and by ion-exchange chromatography. The fractions enriched in sucrose transporter were monitored in three ways: differential labeling, ELISA, and reconstitution in proteoliposomes. When the plasma membranes were differentially labeled by N-ethylamaleimide in the presence of sucrose, a major peak of differential labeling was found at 120 kDa upon gel filtration. When this peak was recovered, denaturated by sodium dodecyl sulfate and reinjected on the gel filtration column, it yielded a peak of differential labeling at 42 kDa. When unlabeled membranes were used, the fractions eluted from the column were monitored by ELISA for their ability to recognize a serum directed against a 42 kDa previously identified as a putative sucrose carrier. The results paralleled those obtained by differential labeling, i.e. a major ELISA-reactive peak was found at 120 kDa upon gel filtration, and this peak yielded a peak most reactive at 40 kDa after denaturation. The 120 kDa peak prepared from unlabeled membranes was further separated on a Mono-Q column. The fractions were monitored by ELISA as described above, and reconstituted into proteoliposomes using asolectin. Active transport of sucrose, but not of valine could be observed with the reconstituted 120 kDa fraction. When the eluates from the Mono-Q column were reconstituted, the fractions exhibiting highest transport activity were enriched with a 42 kDa band. The data provide the first report concerning reconstitution of sucrose transport activity and confirm the involvement of a 42 kDa polypeptide in sucrose transport.

Abstract
The proteins of purified plasma membranes from sugar beet (Beta vulgaris L.) leaf were solubilized and separated on a size exclusion column. The fractions eluted from the column were monitored by ELISA with antibodies directed to a putative sucrose carrier protein. The peak most reactive in ELISA was approximately 120 kDa, and yielded a 40 kDa peak after denaturation by SDS. The 120-kDa peak was recovered and used for reconstitution experiments with asolectin. Upon imposition of an artificial pH gradient and electrical gradient, the obtained proteoliposomes exhibited active transport of sucrose, but not of valine. The active transport of sucrose was inhibited by N-ethylmaleimide and HgCl2.
