Abstract
BACKGROUND As a complex molecule requiring post-translational processing, it has been difficult to produce the Der p 1 major allergen from the Dermatophagoides pteronyssinus house dust mite in a recombinant form. OBJECTIVE Here, we tested whether transgenic tobacco plants are suitable to express Der p 1, either as a wild-type molecule or as variants lacking N-glycosylation sites (Gly(-)) and/or cysteine protease activity (Enz(-)). Methods Using Agrobacterium tumefaciens-based transformation, pro Der p 1 molecules bearing mutations within either the N-glycosylation sites (N34Q, N150Q) and/or the cysteine protease-active site (C132V) were expressed in tobacco plants. After purification by ion exchange chromatography, allergens were characterized using immunoblotting, circular dichroism (CD), as well as basophil and T lymphocyte stimulation assays. RESULTS Four forms of recombinant Der p 1 (i.e. wild-type Gly(+)/Enz(+), as well as Gly(-)/Enz(+), Gly(+)/Enz(-) or Gly(-)/Enz(-) variants) were successfully expressed in tobacco leaves as pro Der p 1 molecules. Spontaneous cleavage of the pro-peptide was observed in tobacco leaf extracts for all forms of recombinant Der p 1 (r Der p 1). CD confirmed that all r Der p 1 molecules, with the exception of the Gly(-)/Enz(-) variant, exhibited secondary structures comparable to the natural protein. A cysteine protease activity was associated only with the Gly(+)/Enz(+) form. All these molecules exhibit a profile similar to natural Der p 1 with respect to IgE immunoreactivity, basophil activation and T cell recognition. CONCLUSION A tobacco plant expression system allows the production of various forms of mature Der p 1, which could be used for diagnostic or immunotherapeutic purposes.

Abstract
This review presents plant-specific characteristics of the Golgi apparatus and discusses their impact on retention of membrane proteins in the Golgi or the trans-Golgi network (TGN). The plant Golgi consists of distinct stacks of cisternae that actively move throughout the cytoplasm. The Golgi apparatus is a very dynamic compartment and the site for maturation of N-linked glycans. It is also a factory for complex carbohydrates that are part of the cell wall. The TGN is believed to be the site from where vacuolar proteins are sorted by receptors towards each type of vacuole. To maintain the structure and specific features of the Golgi, resident proteins ought to be maintained in the proper Golgi cisternae or in the TGN. Two families of membrane proteins will be taken as examples for Golgi/TGN retention: (i) the enzymes involved in N-glycosylation processes and (ii) a vacuolar sorting receptor. Although the number of available plant proteins localized in Golgi/TGN is low, the basis of retention appears to be shared over all kingdoms and may result from pure retention and recycling mechanisms. In this review, we will summarize the characteristics of a plant Golgi and will discuss especially their consequences on on the study of this highly dynamic structure. We then choose membrane proteins with a single transmembrane domain to illustrate the signals and mechanisms involved in plants to localize and maintain proteins in the Golgi and the TGN.

Abstract
Antibodies have long been recognized for their diagnostic and therapeutic potential. The rapidly increasing number of monoclonal antibodies approved for immunotherapy have paved the way to an even greater demand for antibody molecules. In order to satisfy this growing demand, alternative systems based on transgenic organisms are actively explored to increase the production capacity. In this paper, we will focus on transgenic plants as a promising large scale production and processing system.

Abstract
Characterization of a beta1,2-xylosyltransferase from Arabidopsis thaliana (AtXylT) was carried out by expression in Sf9 insect cells using a baculovirus vector system. Serial deletions at both the N- and C-terminal ends proved that integrity of a large domain located between amino acid 31 and the C-terminal lumenal region is required for AtXylT activity expression. The influence of N-glycosylation on AtXylT activity has been evaluated using either tunicamycin or mutagenesis of potential N-glycosylation sites. AtXylT is glycosylated on two of its three potential N-glycosylation sites (Asn51, Asn301, Asn478) and the occupancy of at least one of these two sites (Asn51 and Asn301) is necessary for AtXylT stability and activity. Contribution of the N-terminal part of AtXylT in targeting and intracellular distribution of this protein was studied by expression of variably truncated, GFP-tagged AtXylT forms in tobacco cells using confocal and electron microscopy. These studies have shown that the transmembrane domain of AtXylT and its short flanking amino acid sequences are sufficient to specifically localize a reporter protein to the medial Golgi cisternae in tobacco cells. This study is the first detailed characterization of a plant glycosyltransferase at the molecular level.

Abstract
The presence of an alpha4-fucosyltransferase in plants was first deduced from the characterization of Lewis-a glycoepitopes in some N-glycans. The first plant gene encoding an alpha4-fucosyltransferase was recently cloned in Beta vulgaris. In the present paper we provide evidence for the presence of an alpha4-fucosyltransferase in A. thaliana by measurement of this glycosyltransferase activity from a purified microsomal preparation and by immunolocalization of Le(a) epitopes on glycans N-linked to glycoproteins located to the Golgi apparatus and on the cell surface. The corresponding gene AtFT4 (AY026941) was characterized. A unique copy of this gene was found in A. thaliana genome, and a single AtFT4 transcript was revealed in leaves, in roots, and at a lower extent in flowers. The coding sequence of AtFT4 gene is interrupted by two introns spanning 465 bp and 84 bp, respectively. The putative 393-amino-acid protein (44 kDa, pI: 6.59) contains an N-terminal hydrophobic region and one potential N-glycosylation site, but AtFT4 has poor homology (less than 30%) to the other alpha3/4-fucosyltransferases except for motif II. When expressed in COS 7 cells the protein is able to transfer Fuc from GDP-Fuc to a type 1 acceptor substrate, but this transferase activity is detected only in the culture medium of transfected cells

Abstract
Concanavalin A (ConA), one of the most studied plant lectins, is formed in jack bean (Canavalia ensiformis) seeds. ConA is synthesized as an inactive glycoprotein precursor proConA. Different processing events such as endoproteolytic cleavages, ligation of peptides and deglycosylation of the precursor are required to generate the different polypeptides constitutive of mature ConA. Among these events, deglycosylation of the prolectin appears as a key step in the lectin activation. The detection of deglycosylated proConA in immature jack bean seeds indicates that endoproteolytic cleavages are not prerequisite for its deglycosylation. Both the structure of the lectin precursor N-glycans Man8-9GlcNAc2 and the capacity of Endo H to cleave these oligosaccharide from native proConA in vitro favoured Endo H-type glycosidases as candidates for proConA deglycosylation in planta. Evidence for pH-dependent changes in the prolectin folding were obtained from analysis of the N-glycan accessibility and activation of the deglycosylated lectin precursor in acidic conditions. These data are consistent with the observation that both deglycosylation and acidification of the pH are the minimum requirements to convert the inactive precursor into an active lectin.

Abstract
Plant-specific N-glycosylation can represent an important limitation for the use of recombinant glycoproteins of mammalian origin produced by transgenic plants. Comparison of plant and mammalian N-glycan biosynthesis indicates that beta1,4-galactosyltransferase is the most important enzyme that is missing for conversion of typical plant N-glycans into mammalian-like N-glycans. Here, the stable expression of human beta1,4-galactosyltransferase in tobacco plants is described. Proteins isolated from transgenic tobacco plants expressing the mammalian enzyme bear N-glycans, of which about 15% exhibit terminal beta1,4-galactose residues in addition to the specific plant N-glycan epitopes. The results indicate that the human enzyme is fully functional and localizes correctly in the Golgi apparatus. Despite the fact that through the modified glycosylation machinery numerous proteins have acquired unusual N-glycans with terminal beta1,4-galactose residues, no obvious changes in the physiology of the transgenic plants are observed, and the feature is inheritable. The crossing of a tobacco plant expressing human beta1,4-galactosyltransferase with a plant expressing the heavy and light chains of a mouse antibody results in the expression of a plantibody that exhibits partially galactosylated N-glycans (30%), which is approximately as abundant as when the same antibody is produced by hybridoma cells. These results are a major step in the in planta engineering of the N-glycosylation of recombinant antibodies.

Abstract
The number of therapeutic proteins successfully produced in plants is steadily increasing and is expected to grow even more rapidly in the future. Most therapeutic proteins are glycoproteins and N-glycosylation is often essential for their stability, folding and biological activity. Recombinant glycoproteins of mammalian origin expressed in transgenic plants largely retain their biological activity. However, plants are not ideal for production of pharmaceutical proteins because they produce molecules with glycans that are not compatible with therapeutic applications in humans. As a consequence, strategies to humanise plant N-glycans are now developed. Some of these strategies involve the retention of the recombinant glycoprotein in the endoplasmic reticulum while others are related to the inhibition of endogenous Golgi glycosyltransferases or addition of "new" glycosyltransferases. Data on both the N-glycosylation of therapeutic glycoproteins produced in transgenic plants and current strategies to humanise their N-glycosylation will be discussed in this review.

Abstract
Using pulse-chase experiments combined with immunoprecipitation and N-glycan structural analysis, we showed that the retrieval mechanism of proteins from post-endoplasmic reticulum (post-ER) compartments is active in plant cells at levels similar to those described previously for animal cells. For instance, recycling from the Golgi apparatus back to the ER is sufficient to block the secretion of as much as 90% of an extracellular protein such as the cell wall invertase fused with an HDEL C-terminal tetrapeptide. Likewise, recycling can sustain fast retrograde transport of Golgi enzymes into the ER in the presence of brefeldin A. However, on the basis of our data, we propose that this retrieval mechanism in plants has little impact on the ER retention of a soluble ER protein such as calreticulin. Indeed, the latter is retained in the ER without any N-glycan-related evidence for a recycling through the Golgi apparatus. Taken together, these results indicate that calreticulin and perhaps other plant reticuloplasmins are possibly largely excluded from vesicles exported from the ER. Instead, they are probably retained in the ER by mechanisms that rely primarily on signals other than H/KDEL motifs.

Abstract
Synthesis of parasite specific IgE plays a critical role in the defence against helminth infections. We report here that IgE from serum from Schistosoma mansoni infected mice and Haemonchus contortus infected sheep recognizes complex-type N-glycans from Arabidopsis thaliana, which contain R-GlcNAcbeta1-->4(Fucalpha1-->3)GlcNAcbeta1-Asn (core alpha1-->3-Fuc) and Xylbeta1-->2Manbeta1-->4GlcNAcbeta1-R (core beta1-->2-Xyl) modifications, and honeybee phospholipase A2, which carries N-glycans that contain the core alpha1-->3-Fuc epitope. Evidence is presented that core alpha1-->3-fucosylated N-glycans bind a substantial part of the parasite specific IgE in serum of H. contortus infected sheep. These results suggest that the core alpha1-->3-Fuc antigen may contribute to induction of a Th2 response leading to the production of IgE. In addition we show here that N-glycans carrying core alpha1-->3-Fuc and beta1-->2-Xyl antigens are synthesized by many parasitic helminths and also by the free living nematode Caenorhabditis elegans. Since N-glycans containing the core alpha1-->3-Fuc have also been implicated in honeybee and plant induced allergies, this conserved glycan might represent an important common IgE epitope.

Abstract
The bean lectin phytohemagglutinin (PHA) was expressed in transgenic suspension-cultured BY-2 tobacco cells simultaneously with another recombinant vacuolar protein, the sweet potato sporamin. In contrast to previous observations in different transgenic plant systems when expressed in BY-2 tobacco cells, phytohemagglutinin is mostly but not exclusively targeted to the vacuole. Indeed, a small amount of recombinant phytohemagglutinin is secreted into the culture medium of tobacco cells. Furthermore part of this extracellular phytohemagglutinin has no lectin activity and presents an abnormal glycosylation consistent with higher accessibility of glycans N-linked to these extracellular phytohemagglutinin forms. Phytohemagglutinin secretion occurs regardless of recombinant protein expression level. Consequently, missorting in this case is due to an abnormal phytohemagglutinin conformation or oligomerization rather than to receptor saturation. The treatment of BY-2 cells with drugs, such as monensin and wortmannin, increases even more the transport of phytohemagglutinin to the cell surface through a general inhibition of the sorting mechanisms of vacuolar proteins. The sensitivity to wortmannin is similar for the sorting of phytohemagglutinin and endogenous tobacco chitinase and beta-1,3-glucanase, suggesting that phytohemagglutinin and COOH-terminal propeptide mediated vacuolar sorting share similar mechanisms. A characterization of glycans N-linked to extracellular phytohemagglutinin secreted by monensin- or wortmannin-treated transgenic tobacco cells illustrates that in contrast with monensin, wortmannin completely inhibits the sorting of vacuolar proteins without having any effect on the efficiency of Golgi processing enzymes.

We recently demonstrated the presence of a new asparagine-linked complex glycan on plant glycoproteins that harbors the Lewis a (Lea), or Galbeta(1-3)[Fucalpha(1-4)]GlcNAc, epitope, which in mammalian cells plays an important role in cell-to-cell recognition. Here we show that the monoclonal antibody JIM 84, which is widely used as a Golgi marker in light and electron microscopy of plant cells, is specific for the Lea antigen. This antigen is present on glycoproteins of a number of flowering and non-flowering plants, but is less apparent in the Cruciferae, the family that includes Arabidopsis. Lea-containing oligosaccharides are found in the Golgi apparatus, and our immunocytochemical experiments suggest that it is synthesized in the trans-most part of the Golgi apparatus. Lea epitopes are abundantly present on extracellular glycoproteins, either soluble or membrane bound, but are never observed on vacuolar glycoproteins. Double-labeling experiments suggest that vacuolar glycoproteins do not bypass the late Golgi compartments where Lea is built, and that the absence of the Lea epitope from vacuolar glycoproteins is probably the result of its degradation by glycosidases en route to or after arrival in the vacuole.

Abstract
In order to investigate sequences of tobacco N-acetylglucosaminyltransferase I (GnTI), involved in targeting to and retention in the plant Golgi apparatus the cytoplasmic transmembrane stem (CTS) region of the enzyme was cloned in frame with the cDNA of the green fluorescent protein (gfp) and subsequently transiently expressed in Nicotiana benthamiana plants using a tobacco mosaic virus (TMV) based expression vector. Confocal laser scanning microscopy showed small fluorescent vesicular bodies in CTS-gfp expressing cells, while gfp alone expressed in control plants was uniformly distributed in the cytoplasm. The CTS-gfp fusion protein colocalised with immunolabelling observed by an antibody specific for the Golgi located plant Lewis a epitope. Furthermore, treatment with brefeldin A, a Golgi specific drug, resulted in the formation of large fluorescent vesiculated areas. These results strongly suggest a Golgi location for CTS-gfp and as a consequence our findings reveal that the N-terminal 77 amino acids of tobacco GnTI are sufficient to target to and to retain a reporter protein in the plant Golgi apparatus and that TMV based vectors are suitable vehicles for rapid delivery of recombinant proteins to the secretory pathway.

Abstract
Protein transport along the secretory pathway is supported by a noria of vesicles that bud and fuse, load and unload their cargo from one compartment into the other. However, despite this constant flow-through of proteins and lipids the various compartments of the secretory pathway are able to maintain their own specific composition. Here, we discuss recent insights into mechanisms of protein retention and localization that are necessary for the maintenance of endoplasmic reticulum (ER)- and Golgi-associated typical functions such as protein folding and glycosylation in plant cells.

Abstract
Plant cells (Nicotiana tabacum) were genetically modified to produce an heterologous protein, the acidic invertase from carrot, and invertase production from suspension tobacco cells was investigated. Suspension cultures were grown in shake flasks and stirred bioreactor. Total invertase activity was growth related. A 75 d continuous culture in 10 l bioreactor was performed. Our study demonstrates the high potential of plant cell cultures for long term production of heterologous protein.

Abstract
N-glycosylation is a major modification of proteins in plant cells. This process starts in the endoplasmic reticulum by the co-translational transfer of a precursor oligosaccharide to specific asparagine residues of the nascent polypeptide chain. Processing of this oligosaccharide into high-mannose-type, paucimannosidic-type, hybrid-type or complex-type N-glycans occurs in the secretory pathway as the glycoprotein moves from the endoplasmic reticulum to its final destination. At the end of their maturation, some plant N-glycans have typical structures that differ from those found in their mammalian counterpart by the absence of sialic acid and the presence of beta(1,2)-xylose and alpha( 1,3)-fucose residues. Glycosidases and glycosyltransferases that respectively catalyse the stepwise trimming and addition of sugar residues are generally considered as working in a co-ordinated and highly ordered fashion to form mature N-glycans. On the basis of this assembly line concept, fast progress is currently made by using N-linked glycan structures as milestones of the intracellular transport of proteins along the plant secretory pathway. Further developments of this approach will need to more precisely define the topological distribution of glycosyltransferases within a plant Golgi stack. In contrast with their acknowledged role in the targeting of lysosomal hydrolases in mammalian cells, N-glycans have no specific function in the transport of glycoproteins into the plant vacuole. However, the presence of N-glycans, regardless of their structures, is necessary for an efficient secretion of plant glycoproteins. In the biotechnology field, transgenic plants are rapidly emerging as an important system for the production of recombinant glycoproteins intended for therapeutic purposes, which is a strong motivation to speed up research in plant glycobiology. In this regard, the potential and limits of plant cells as a factory for the production of mammalian glycoproteins will be illustrated.

Abstract
In plants, N-linked glycans are processed in the Golgi apparatus to complex-type N-glycans of limited size containing a beta(1,2)-xylose and/or an alpha(1,3)-fucose residue. Larger mono- and bi-antennary N-linked complex glycans have not often been described. This study has re-examined the structure of such plant N-linked glycans, and, through both immunological and structural data, it is shown that the antennae are composed of Lewis a (Le(a)) antigens, comprising the carbohydrate sequence Gal beta 1-3[Fuc alpha 1-4]GlcNAc. Furthermore, a fucosyltransferase activity involved in the biosynthesis of this antigen was detected in sycamore cells. This is the first characterization in plants of a Lewis antigen that is usually found on cell-surface glycoconjugates in mammals and involved in recognition and adhesion processes. Le(a)-containing N-linked glycans are widely distributed in plants and highly expressed at the cell surface, which may suggest a putative function in cell/cell communication.

Abstract
Proteins are co-translationally transferred into the endoplasmic reticulum (ER) and then either retained or transported to different intracellular compartments or to the extracellular space. Various molecular signals necessary for retention in the ER or targeting to different compartments have been identified. In particular, the HDEL and KDEL signals used for retention of proteins in yeast and animal ER have also been described at the C-terminal end of soluble ER processing enzymes in plants. The fusion of a KDEL extension to vacuolar proteins is sufficient for their retention in the ER of transgenic plant cells. However, recent results obtained using the same strategy indicate that HDEL does not contain sufficient information for full retention of phaseolin expressed in tobacco. In the present study, an HDEL C-terminal extension was fused to the vacuolar or extracellular (delta pro) forms of sporamin. The resulting SpoHDEL or delta proHDEL, as well as Spo and delta pro, were expressed at high levels in transgenic tobacco cells (Nicotiana tabacum cv BY2). The intracellular location of these different forms of recombinant sporamin was studied by subcellular fractionation. The results clearly indicate that addition of an HDEL extension to either Spo or delta pro induces accumulation of these sporamin forms in a compartment that co-purifies with the ER markers NADH cytochrome C reductase, binding protein (BiP) and calnexin. In addition, a significant SpoHDEL or delta proHDEL fraction that escapes the ER retention machinery is transported to the vacuole. From these results, it may be proposed that, in addition to its function as an ER retention signal, HDEL could also act in quality control by targeting chaperones or chaperone-bound proteins that escape the ER to the plant lysosomal compartment for degradation.

Abstract
Three laccase-encoding cDNAs were cloned from a tobacco stem cDNA library. One of them contains a full length sequence coding for a cationic laccase. The predicted polypeptide sequence shows 48% identity with sycamore laccase. Amino acid comparisons with other laccases and ascorbate oxidases have shown that this new plant laccase sequence also contains four potential copper binding regions which are highly conserved among the blue copper oxidases.

Abstract
Antisera raised against the plant glycoproteins beta-fructosidase and horseradish peroxidase can be fractionated on an affinity column of honeybee venom phospholipase A2 to produce serum fractions that are specific for either the alpha 1-->3 fucose or beta 1-->2 xylose epitopes commonly found on the Asn-linked glycans of plant glycoproteins. This affinity purification strategy relies on the absence of beta 1-->2 xylose from the glycan of the venom protein. Such antibody preparations can be used for the detection of these sugar epitopes on glycoproteins.

Abstract
Antibodies specific for xylose-containing plant complex N-linked glycans are used for indirect immunolocalization of xylosyltransferase in sycamore cells. The use of high pressure freezing and freeze substitution for sample preparation resulted in very good morphological preservation of the different Golgi cisternae. Xylosyltransferase shows a diffuse distribution all over the Golgi stacks and xylosylation appears to be an early processing event that is initiated in the cis Golgi compartment.
