Reconstitution of acetosyringone-mediated Agrobacterium tumefaciens virulence gene expression in the heterologous host Escherichia coli.
The ability to utilize Escherichia coli as a heterologous system in which to study the regulation of Agrobacterium tumefaciens virulence genes and the mechanism of transfer DNA (T-DNA) transfer would provide an important tool to our understanding and manipulation of these processes. We have previously reported that the rpoA gene encoding the alpha subunit of RNA polymerase is required for the e...
متن کاملA Preliminary Experiment on Agrobacterium tumefaciens-Mediated Transformation of the P5CS1 GENE in Tall Fescue
Abiotic stress conditions can be imposed on plants through either poor water quality or adverse climate condition. These types of stress affect plant growth and development throughout their life cycle. Plants that are tolerant to drought are therefore valuable, and turf grasses have the potential to grow tolerant. Turf grasses provide ground cover and offer multiple benefits, from their aesthet...
متن کاملPCR-mediated Expression of the Human GM-CSF Gene in Escherichia coli
Four exons of the human genomic GM-CSF gene were assembled together using gene splicing by overlap extension (SOE) method. The resulting nucleotide sequence was cloned in the pET23a(+) expression vector under the control of strong bacteriophage T7 transcription and translation signals. The construct obtained was Transferred into the E. coli strain, BL21(DE3) pLysS and IPTG was used for inducti...
متن کاملThe chromosomal response regulatory gene chvI of Agrobacterium tumefaciens complements an Escherichia coli phoB mutation and is required for virulence.
In an effort to identify the Agrobacterium tumefaciens phosphate regulatory gene(s), we isolated a clone from an A. tumefaciens cosmid library that restored regulated alkaline phosphatase activity to an Escherichia coli phoB mutant. The gene that complemented phoB was localized by subcloning and deletion analysis, and the DNA sequence was determined. An open reading frame, denoted chvI, was ide...
متن کاملAn Improved Binary Vector and Escherichia coli Strain for Agrobacterium tumefaciens-Mediated Plant Transformation
The plasmid vector pGreenII is widely used to produce plant transformants via a process that involves propagation in Escherichia coli However, we show here that pGreenII-based constructs can be unstable in E. coli as a consequence of them hampering cell division and promoting cell death. In addition, we describe a new version of pGreenII that does not cause these effects, thereby removing the s...
