ABSTRACT: Fungal diseases like early blight, late blight, fusarium wilt cause 30-40 per cent loss in fruit production. Form past decade many transgenic plants had been developed using genes encoding chitinases and glucanases with the objective of imparting fungal disease resistance. Since the genes encoding chitinase and glucanase act synergistically. The study was performed to construct plant transformation vector pRAGS carrying both ech42 and bgn under single T-DNA region. Initially, HindIII site at 5' end of earlier cloned bgn (T. harzianum) was removed using primers during reamplification of the gene. The amplicons were cloned into pTZ57R/T containing T overhangs at Eco321 site and transferred to E. coli DH5a and further to plant transformation vector pBI121 which was named as pRA121. In order to clone another gene (ech42) into pRA121, expression cassette from iHP vector was transferred to pRA121 and named as pRAG121. Further in order to gain XhoI site for cloning ech42 gene into pRAG121, ech42 (pSUM1) was cloned into pYES2/CT, named as pSAG1, ech42 from pSAG1 cloned with KpnI and XhoI in pRAG121 and named as pRAGS121. The vector constructed in the present study can be used to transform important crop plants to have enhanced resistance to fungal diseases.

Eggplant is a fruit vegetable of family Solanaceae, and eggplant fruits are of different shape and sizes that render them as an ideal system for metabolic engineering. Here, we have developed an agroinfiltration protocol for the transient expression of a gene in the eggplant fruit using GUS bearing; pCAMBIA1304 vector. Thereafter, to prove the effectiveness of the developed protocol, we have used the eggplant hydroxycinnamoyl CoA-quinate transferase (SmHQT), which is the central enzyme studied to increase the chlorogenic acid content, in a gene construct with the specific promoter in a plant transformation vector (pBIN19). Also, in our cassette, we also co-expressed the P19 protein of Tomato bushy stunt virus (native promoter) to overexpress the protein. Overall, using the protocol, the chlorogenic content was increased by more than two folds in the transgenic tissues.

The VirEl protein plays a key role in the transport of VirE2 protein from the bacterium to the plant cell during crown gall tumor induction by Agrobacterium. The virEl gene of A. tutnefaciens pTiA6 was cloned into the plant transformation vector pTd33 yielding pTd93virEl that was introduced into A. tuniefaciens EHA101 and used for tobacco transformation. The presence of the foreign DNA in the putative transgenic plants was confirmed by PCR analysis. Nine of the 41 transformed plants formed only small tumors following infection with the wild-type A. vitis octopine strain AB3. This property was inherited into the T1 generation. The expression of virEl gene in TI plants was demonstrated by Northern blot analysis.

ABSTRACT The production of a recombinant human IgG1 in transgenic tobacco was examined to determine whether a plant-derived antibody could recruit immune system effector function against a bacterial pathogen. A plant transformation vector was engineered to contain genes for a human kappa light chain and a human gamma-1 heavy chain with VH and VL sequences from a previously identified human IgG2 monoclonal antibody (MAb) that specifically binds to and opsonizes Pseudomonas aeruginosa serotype O6ad. Unique NcoI and NotI restriction sites were incorporated to flank these variable sequences, resulting in a plant transformation vector that could be engineered for expression of any other human IgG1 antibody, requiring only the substitution of other VH and VL antigen-binding coding sequences. The plant-produced IgG1 was determined to have high-mannose glycan content and to be capable of mediating opsonophagocytosis of P. aeruginosa serotype O6ad in vitro using human complement and human polymorphonuclear leukocytes. Thus, MAbs produced in plants from this vector could provide human IgG1 MAbs for targeting other pathogens that require the recruitment of immune system effector functions.
