Genetic transformation results from a complex interaction between Agrobacterium and host plant cells. However, we understand much less about the plant contribution to the transformation process. Plant species, and even varieties/ecotypes, differ markedly in their susceptibility to Agrobacterium. A genetic component underlies these differences, permitting scientists to identify specific host genes and proteins mediating transformation. In this chapter, I review what is known about the plant contribution to transformation, and the tools which scientists are using to reveal the mechanisms by which host genes and proteins function in various steps of the transformation process. However, our knowledge of the host contribution to the transformation process has lagged. It is clear that although Agrobacterium has an enormous host range encompassing species of numerous phylogenetic kingdoms, differences in susceptibility to Agrobacterium-mediated transformation abound among plant species. Physiological or environmental effects may account for some of these disparities, but a genetic basis also underlies host susceptibility or resistance. For example, a recent survey of approximately 40 Arabidopsis thaliana ecotypes indicated vastly disparate responses to root transformation (Nam et al. In addition, various plant tissues or organs can respond differently to infection by a particular Agrobacterium strain (Grevelding et al. The existence of a genetic basis underlying host susceptibility to Agrobacterium-mediated transformation has allowed us to conduct genetic screens for specific plant genes that contribute to the transformation process. These screens have resulted the identification of more than 125 Arabidopsis genes involved in transformation (Zhu et al. Cell and molecular biology methodologies have also been combined with bioinformatics approaches to investigate plant genes responding to Agrobacterium infection and which, thus, may play a role in transformation (Ditt et al. In this chapter, I shall review some of the methodologies that we and others have used to identify host genes that mediate plant genetic transformation by Agrobacterium. I shall also describe how we believe these genes function to help effect transformation. Finally, I shall illustrate how Agrobacterium-Mediated Plant Transformation Process 485 manipulation of some of these genes may be used to improve the transformation of recalcitrant plant species. Such differences may simply have reflected the particular Agrobacterium strain or assay condition used to determine susceptibility. Monocotyledonous plants were initially considered non-hosts for Agrobacterium, primarily because they could not be shown to support the growth of crown gall tumors. However, tumor production was eventually detected on the monocot species Asparagus officinalis and Dioscorea bulbifera (Bytebier et al. As mentioned above, the first extensive investigation of a genetic basis for plant susceptibility to Agrobacterium-mediated transformation was a study conducted by Nam et al. These authors determined root transformation-susceptibility of approximately 40 different ecotypes of Arabidopsis thaliana.

One interpretation of these results is that many of the proteins identified in their outer membrane preparation are possibly contaminants of the periplasm or inner membrane medicine werx trecator sc 250mg on-line. Thus medications like zoloft order trecator sc 250mg amex, we believe that the small number of protein species identified by our isolation method represent a more accurate account of the outer membrane protein composition of T treatment wasp stings cheap trecator sc 250 mg line. While lipoproteins are integral membrane proteins medications that cause weight gain buy 250mg trecator sc overnight delivery, their membrane association extends only to integration of the lipid moiety in the bilayer. By comparison, one type of membrane-spanning protein common to virtually all gram-negative outer membranes are porins, which form water-filled Emerging Infectious Diseases 14 Vol. Porin proteins, like almost all outer membrane proteins, span membranes in a beta-pleated sheet topology rather than in alpha helical hydrophobic regions, which are common to inner membranespanning proteins (30). Porin activity can be detected by several methods (29), including radioisotope efflux or substrate uptake in proteoliposomes, liposome swelling, and the black lipid bilayer assay, which measures the conductivity of ions through porin channels. In the black lipid bilayer assay, a set voltage is applied across an artificial lipid bilayer which, if a porin protein has been inserted, results in an increase in electrical conductance. The degree of conductance increase for many insertional events is used to calculate the average pore channel size. When the black lipid bilayer assay was used with Triton X-100 detergent solubilized proteins from our purified T. At the time, the two distinct conductance measurements suggested two different porin species, or alternatively, that the larger activity could be the result of dimeric aggregates of the smaller activity or the smaller activity could be a substate of the larger channel, possibly caused by the application of a voltage (31). This finding was of particular importance since several gram-negative bacterial porins play a role in pathogenesis by acting as adhesins (32,33) and as surface targets of bactericidal antibody (34-37). Pallidum Rare Outer Membrane Protein 1 (Tromp1): an Outer Membrane Porin Since most porin proteins have molecular masses of 28 to 48-kDa (29), our focus was directed toward isolating the 28- and 31-kDa proteins identified in purified T. Internal amino acid sequences from the native 31-kDa protein were used to clone the encoding structural gene, designated tromp1 (38). Antiserum generated to a recombinant Tromp1 fusion protein has shown that both 31-kDa proteins identified by two-dimensional blot analysis of outer membrane are Tromp1. Analysis of the deduced amino acid sequence showed an N-terminal hydrophobic region consistent with a signal peptide. Two potential leader peptidase I cleavage sites are noted, including threonine-histidine-alanine at residues 30 through 32 and alanine-alaninealanine at residues 38 through 40. Identification of the cleavage site by N-terminal amino acid sequence of the native protein has not been possible because of the limited amount of native protein recoverable. However, other data discussed later in this review suggest that alanine-alaninealanine is the correct cleavage site. The deduced Tromp1 amino acid sequence also supports the concept that Tromp1 topology is in accord with the structural paradigms of other gram-negative outer membrane proteins. Beta-moment analysis, which shows amphipathic sequence regions, has predicted that Tromp1 has 14 membrane-spanning amphipathic beta-sheet segments typical of gram-negative outer membrane proteins (29,30). The lethality for Escherichia coli transformants harboring the intact tromp1 structural gene, which was found by immunoblot analysis to be expressing Tromp1, is similar to that observed for many recombinant gram-negative porin proteins expressed in E. The tromp1 gene has recently been found to be part of a putative transport operon that includes an adenosine triphosphate binding protein and a hydrophobic membrane protein (Hardham et al. To determine if Tromp1 was a porin, native Tromp1 was purified from Triton X-100 solubilized T. The demonstration of porin activity, by the black lipid bilayer assay, has confirmed that Tromp1 is a membrane-spanning outer membrane protein of T. Antiserum against a Tromp1 fusion protein has in fact identified two higher molecular mass forms of native Tromp1 on immunoblots of T. A 98-kDa size is further found to be the only detectable form of native Tromp1 when T. These findings would appear to be consistent with the idea that native Tromp1 exists in the T. Expression of a Porin Active Recombinant Tromp1 (rTromp1) Porin proteins of gram-negative pathogens not only function as portals for nutrient acquisition across the outer membrane but also play a role in pathogenesis by acting as adhesins (32,33) and targets for bactericidal antibody (34-37). The membrane-spanning conformation of membrane porins is critical for their biologic function. Many surface-exposed epitopes on porins shown to be targets for bactericidal antibodies are conformational (34,36).

The considerable overlap between actions of individual cytokines and interleukins is summarized in Table 1 treatment molluscum contagiosum effective trecator sc 250 mg. Cytokines that induce chemotaxis of leucocytes are referred to symptoms 28 weeks pregnant trecator sc 250mg discount as chemokines medicine ethics discount trecator sc 250mg line, a name derived from chemo + kine medicine allergic reaction purchase trecator sc 250 mg, i. Some cytokines and interleukins have been redefined as chemokines as their function becomes clearer. Chemokines are structurally similar proteins of small molecule size (8­10 kDa), which are able to diffuse from the site of production to form a local concentration gradient along which granulocytes and lymphocytes can migrate towards the stimulus. There are two types of movement: migration of leucocytes to sites of inflammation and that of differentiating cells moving to a specific activation site (see section 1. There is little free IgD or IgE in serum or normal body fluids, since both act as surface receptors on mature B cells or mast cells respectively. Once V, D and J region rearrangement has taken place, further variation is introduced when antibodies are made, by the introduction of point mutations in the V region genes. Somatic hypermutation helps to increase the possible number of combinations and accounts for the enormous diversity of antibody specificities (1014), which by far exceeds the number of different B cells in the body (1010). Molecules for lysis and killing the other major sets of effector molecules are the cytolytic molecules, though less is known about their diversity or mechanisms of action. These cell types also secrete granzymes, enzymes that induce apoptosis in target cells (Table 1. The duplication of the functions of this essential phylogenetically ancient protein during evolution underlines the continued development of mammalian immunity to keep up with microbial invaders. There are other structurally similar cytokine receptors, leading to the classification of these receptors into five families of similar types of receptors, many of which have similar or identical functions, providing a safety net (redundancy) for their functions, which are crucial for both the innate and adaptive immune systems. Chemokine receptors from a family of G protein coupled receptors ­ meaning that they are transmembrane and able to Chapter 1: Basic Components: Structure and Function / 15 activate internal signalling pathways. There are also FcRn involved in the transfer of IgG across the placenta and these receptors are also involved in IgG recirculation and catabolism. IgE receptors are found on mast cells, basophils and eosinophils for triggering degranulation of these cells. IgA receptors ensure the transport of polymeric IgA across the mucosal cells and other, possibly important, functions are slowly being defined. Complement receptors for fragments of C3 produced during complement activation also provide a mechanism for phagocytosis and are found on macrophages and neutrophils. Adhesion molecules are grouped into two major families: (i) integrins and (ii) selectins (Table 1. The migration of leucocytes to sites of inflammation is dependent on three key sequential steps mediated by adhesion molecules. Depending on the structure of the subunit, integrins are subdivided into five families (1 to 5 integrins). Examples in other systems include 3 to 5 integrins mediate cell adhesion to extracellular matrix proteins such as fibronectin and vitronectin in the skin and laminin receptor in muscle. The selectin family is composed of three glycoproteins designated by the prefixes E (endothelial), L (leucocyte) and P (platelet) to denote the cells on which they were first described. Selectins bind avidly to carbohydrate molecules on leucocytes and endothelial cells and regulate the homing of the cells to sites of inflammation (see sections 1. To reach the site of invasion and destroy the pathogens, the components of the immune systems have to know where to go and to how to breach the normal barriers, such as the endothelial cells of the vascular system. Humoral factors (such as antibodies and complement) are carried in the blood and enter tissues following an increase in permeability associated with inflammation. Immune cells (innate and antigen specific) are actively attracted to a site of inflammation and enter the tissues via specific sites using active processes of adhesion. Non-specific immunity is older, in evolutionary terms, than antibody production and antigen-specific T cells. The major cells involved in the innate system are phagocytic cells (macrophages and polymorphonuclear leucocytes), which remove antigens including bacteria, and dendritic cells which are the first cells to react to invaders.
