Genetic engineering for fungal and bacterial diseases.
Significant new advances at the molecular level in the field of plant-pathogen interactions form the basis for novel transgenic approaches to crop protection. The cloning of disease resistance genes and the dissection of the signal transduction components of the hypersensitive response and systemic acquired resistance pathways have greatly increased the diversity of options available for transg...
متن کاملBacterial Nanofluidic Structures for Medicine and Engineering Bacterial nanotubes Bacterial Nanofluidic Structures for Medicine and Engineering
2010 Wil re microscopic, single-celled organisms that utilize a variety of nanofluidic structures. One of the best known and widely used nanofluidic structures that are derived from bacteria is the a-hemolysin pore. This pore, which self-assembles in lipid bilayers, has been used for a wide variety of sensing applications, most notably, DNA sensing. Synthetic pores drilled in a wide variety of ...
متن کاملEcological fitness, genomic islands and bacterial pathogenicity
The compositions of bacterial genomes can be changed rapidly and dramatically through a variety of processes including horizontal gene transfer. This form of change is key to bacterial evolution, as it leads to ‘evolution in quantum leaps’. Horizontal gene transfer entails the incorporation of genetic elements transferred from another organism—perhaps in an earlier generation—directly into the ...
متن کاملGenetic Programming without Fitness
This paper provides a short, informal illustration of a selection scheme based on the key idea of competition, particularly suited for genetic programming, which provides a way to do without the explicit deenition of a tness function. In many tasks, competition between two individuals on one problem instance chosen according to some probability can be a valid alternative to deening an appropria...
متن کاملGenetic analysis of a plasmid-encoded, host genotype-specific enhancement of bacterial fitness.
In the absence of antibiotics, carriage of pACYC184 reduces the competitive fitness of an Escherichia coli B genotype that was not previously selected for plasmid carriage, relative to that of an isogenic plasmid-free competitor. However, a host genotype propagated with the plasmid for 500 generations evolved an unexpected competitive advantage from plasmid carriage, relative to its own isogeni...
