Abstract
Lectins are proteins with a high degree of stereospecificity to recognize various sugar structures and form reversible linkages upon interaction with glyco-conjugate complexes. These are abundantly found in plants, animals and many other species and are known to agglutinate various blood groups of erythrocytes. Further, due to the unique carbohydrate recognition property, lectins have been extensively used in many biological functions that make use of protein-carbohydrate recognition like detection, isolation and characterization of glycoconjugates, histochemistry of cells and tissues, tumor cell recognition and many more. In this review, we have summarized the immunomodulatory effects of plant lectins and their effects against diseases, including antimicrobial action. We found that many plant lectins mediate its microbicidal activity by triggering host immune responses that result in the release of several cytokines followed by activation of effector mechanism. Moreover, certain lectins also enhance the phagocytic activity of macrophages during microbial infections. Lectins along with heat killed microbes can act as vaccine to provide long term protection from deadly microbes. Hence, lectin based therapy can be used as a better substitute to fight microbial diseases efficiently in future.

Abstract
An Apios americana lectin (AAL) and a lectin-like protein (AALP) were purified from tubers by chromatography on Butyl-Cellulofine, ovomucoid-Cellulofine, and DEAE-Cellulofine columns. AAL showed strong hemagglutinating activity toward chicken and goose erythrocytes, but AALP showed no such activity toward any of the erythrocytes tested. The hemagglutinating activity of AAL was not inhibited by mono- or disaccharides, but was inhibited by glycoproteins, such as asialofetuin and ovomucoid, suggesting that AAL is an oligosaccharide-specific lectin. The cDNAs of AAL and AALP consist of 1,093 and 1,104 nucleotides and encode proteins of 302 and 274 amino acid residues, respectively. Both amino acid sequences showed high similarity to known legume lectins, and those of their amino acids involved in carbohydrate and metal binding were conserved.

Abstract
A lectin was isolated from the roots of Sesbania aculeata. This is a glucose specific lectin having 39 kDa subunit molecular weight. The expression of this lectin was found to be developmentally regulated and observed to be the highest in the second week. The lectin was purified by affinity chromatography using Sephadex G-50 and found to have 28% homology with Arabidopsis thaliana lectin-like protein (accession No. CAA62665). The lectin binds with lipopolysaccharide isolated from different rhizobial strains indicating the plants interaction with multiple rhizobial species.

Abstract
Isolation and purification of a alpha-methyl-mannoside specific lectin (SL-I) of peanut was reported earlier [Singh and Das (1994) Glycoconj J 11:282-285]. Native SL-I is a glycoprotein having approximately 31 kDa subunit molecular mass and forms dimer. The gene encoding this lectin is identified from a 6-day old peanut root cDNA library by anti-SL-I antibody and N-terminal amino acid sequence homology to the native lectin. Nucleotide sequence derived amino acid sequence of the re-SL-I shows amino acid sequence homology with the N-terminal and tryptic digests' amino acid sequence of the native SL-I (nSL-I). Presence of a putative glycosylation (QNPS) site and a hydrophobic adenine-binding (VLVSYDANS) site is also identified in SL-I. Homology modeling of the lectin suggests it to be an archetype of legume lectins. It is expressed as a approximately 30 kDa apoprotein in E. coli and has the carbohydrate specificity and secondary structure identical to its natural counterpart. The lectin SL-I inhibits cytokinin 6-benzylaminopurine (BA)-induced "delayed leaf senescence" and "cotyledon expansion". Equilibrium dialysis revealed a single high-affinity binding site for adenine (7.6 x 10(-6 )M) and BA (1.09 x 10(-5 )M) in the SL-I dimer and thus suggesting that the cytokinin antagonist effect of SL-I is mediated by the direct interaction of SL-I with BA.

Abstract
Ribosome-inactivating proteins having antitumor and immunomodulatory properties constitute the active principle of widely used mistletoe therapy in Europe. This is the first report of the four isoforms of Himalayan mistletoe ribosome-inactivating proteins (HmRips) from Viscum album parasitized on wild apple inhabiting NW Himalayas. HmRips were purified by affinity chromatography and four isoforms were separated by ion-exchange chromatography. HmRip 1, 2, 3, and 4 have isoelectric points of 6.6, 6.1, 5.2, and 4.7, respectively. Disulfide linked toxin and lectin subunits of HmRip 1 and 2 isoforms have molecular weights of 28 and 34kDa while those of HmRip 3 and 4 have 28 and 32kDa. The isoforms lacked blood group specificity and showed positive activity with seven mammalian erythrocyte types but did not show any activity with avian erythrocyte type. Lectin activity of HmRips remained unchanged for a wide range of temperatures (0-65 degrees C) and pH (3-9). Unlike other type II Rips, the HmRip 1, 2, and 4 showed unique affinity towards l-rhamnose, meso-inositol, and l-arabinose while HmRip 3 has specificity to gal/galNAc. Sugar binding studies with 22 sugars also suggested that the C-4 hydroxyl of galactose might be the critical site involved in sugar binding of HmRips. Type II Rips are known to be galactoside specific and do not have affinity for l-rhamnose and meso-inositol. However, HmRip 1, 2, and 4 having equal affinity for galactose and l-rhamnose do not strictly fit into any of the four structural classes of the lectins and represent a new class of type II Rips and plant lectins.

Abstract
A cDNA clone obtained from developing peanut (Arachis hypogaea) seedling roots, when expressed in Escherichia coli and insect cells (Sf9) gave a 29 kDa subunit protein. The native recombinant protein agglutinates neuraminidase treated human erythrocytes and the agglutination is inhibited by galactose. Nucleotide sequence and predicted amino acid sequence analyses indicate that it is different from peanut seed (PNA and SGL) and nodule (NGLa and NGLb) galactose-binding lectins.

Abstract
Dioclea lehmanni seeds are known to contain two lectins [G. Pérez, M. Hernández, E. Mora, Isolation and characterization of a lectin from the seeds of Dioclea lehmanni, Phytochemistry 29 (1990) 1745-1749]. Taking advantage of the strong bond shown by one of them (Dioclea lehmanni lectin I) to Sephacryl S-200, it has been purified and characterized as a Glc/Man lectin very similar to Concanavalin A. In order to compare the properties of the two lectins, we purified the second one (Dioclea lehmanni lectin II) to homogeneity by gel filtration and hydrophobic chromatography. Dioclea lehmanni lectin II is a dimeric protein (58.4 kDa) with identical subunits with M(r) = 29,000. Its molecular properties, carbohydrate specificity, human and animal erythroagglutination pattern, amino acid composition and N-terminal sequence (27 residues) were determined. These features clearly distinguish lectin II from lectin I; therefore a second novel lectin is present in the seeds of Dioclea lehmanni.

Abstract
Sugar specific binding of peanut root lectin (PRA II) to peanut specific bradyrhizobial lipopolysaccharides (LPS) was demonstrated by gel retardation assay and lectin based ELISA. Sephadex G-50 gel purified high molecular weight polysaccharides from NC 92 LPS bind PRA II most efficiently. Binding of NC 92 LPS only to PRA II and not to PNA, SBA and PSL by Western blot analysis suggests that this lectin-LPS interaction is tissue as well as species specific.

Abstract
The glucose-specific peanut root lectin, PRA II, is localized on the surface of 7-day-old peanut seedling root and in root cortical parenchymatous cells. The lectin is eluted from intact roots upon washing with buffer containing glucose. Rabbit erythrocytes bind to the root surface and the cortical cells; the binding is inhibited by antibodies raised against PRA II, peanut-specific Rhizobium cells and by glucose. Lipopolysaccharides isolated from host-specific Rhizobium strain inhibit the haemagglutinating activity of PRA II and are precipitated by the lectin. Our results suggest that PRA II might be involved in recognition of Rhizobium by peanut roots.

Abstract
The stem of the peanut plant contains two lectins, a methyl alpha-mannoside specific lectin (SL-I) and a lactose/cellobiose specific lectin (SL-II). These lectins are found to be developmentally regulated and maximum activities are observed in 3-4-weeks-old plants. The two lectins SL-I and SL-II have been purified from 3-week-old stem by affinity chromatography on Sephadex G-50 and guar gum matrices respectively. Both are glycosylated lectins and have the identical subunit molecular weight of 31 kDa.
