results this study shows the prepared gene construct is inducible by glucose. gene expression of preproinsulin was observed in muscle tissue of rabbits. conclusions these finding indicated that research in diabetes mellitus gene therapy could be performed on larger animals. objectives the purpose of this study was to construct glucose inducible insulin gene plasmid and use it in the muscle tiss...

We describe a plant protoplast transformation method that provides transformants with a simple pattern of integration of a foreign gene. The approach is to deliver into plant protoplasts by direct gene transfer the Agrobacterium virulence genes virD1 and virD2 with or without virE2, together with a target plasmid containing a gene of interest flanked by Agrobacterium T-DNA border repeat sequenc...

Agrobacterium tumefaciens is established as a vector for gene transfer in many dicotyledonous plants but is not accepted as a vector in monocotyledonous plants, especially in the important Gramineae. The use of Agrobacterium to transfer genes into monocot species could simplify the transformation and improvement of important crop plants. In this report we describe the use of Agrobacterium to tr...

abstract lettuce (lactuca sativa l.) is a major leafy vegetable and belongs to the asteraceae family (compositae). the genetic manipulation of lettuce requires a reliable and efficient regeneration method. since lettuce is a suitable bioreactor for production of recombinant proteins especially edible vaccines. this study was conducted to identify an appropriate method for lettuce gene transform...

BACKGROUND Agrobacterium tumefaciens strain GV3101 (pMP90) is widely used in transient gene expression assays, including assays to study pathogen effectors and plant disease resistance mechanisms. However, inoculation of A. tumefaciens GV3101 into Nicotiana tabacum (tobacco) leaves prior to infiltration with pathogenic and non-host strains of Pseudomonas syringae results in suppression of macro...

Agrobacterium rhizogenes causes hairy root growth on a large number of plant species. It does so by transferring specific DNA fragments (T-DNA) from its root-inducing plasmid (pRi) into plant cells. Expression of T-DNA genes leads to abnormal root growth and production of specific metabolites (opines) which are taken up by the bacterium and used for its growth. Recent work has shown that severa...

Lagerstroemia indica is an important woody ornamental plant worldwide. However, the application of many technologies, such as transgenic breeding and genome editing, has been severely hampered due to lack efficient calli induction regeneration technology. Here, we discussed a reliable protocol using whole-leaf explants. This protocol’s effectiveness for systems in crape myrtle were up 70.33% 44...

Agrobacterium tumefaciens is capable to transfer genes across kingdoms. It can genetically transform not only plant cells, but also many other bacterial, algal, fungal, animal and human cells. This depends on the interactions among a variety of both Agrobacterium and host genes. Inside the host cell, RAD52 which is involved in DNA repair is a key gene determining integration of T-DNA by homolog...

Agrobacterium rhizogenes ATCC 15834 wild type strain was transformed with the binary vector pBI121 using the heat shock method. The transformed Agrobacterium was then tested for virulence through tobacco leaf explant transformation. Compared to the non-transformed Agrobacterium, the transformed Agrobacterium showed reduced virulence, producing signifi cantly lower number of hairy roots in tobac...
