Genetic Manipulation for Improvement of Microbial Biocontrol Agents
1999During the last few years genetic modification of microorganisms to improve their biological control of plant pathogens has created some very interesting results, which indicates that molecular biology can be used not only to understand the mechanism behind biological control, but also to improve biocontrol ability.

Genetic Improvement of Entomopathogenic Nematodes for Insect Biocontrol
2002Entomopathogenic nematodes (families Heterorhabditidae and Steinernematidae) are the most important biological-control agents for soil-dwelling insect pests (Gaugler and Kaya, 1990). Several species of Heterorhabditids and Steinernematids are produced commercially and used as biotic insecticides.

Molecular Genetics of the Biocontrol Agents Trichoderma spp
1991ABSTRACT We have developed conditions for an efficient method of genetic transformation for the biocontrol agents Trichoderma spp, using polyethylene glycol (PEG) and CaCl 2 or high-voltage electroporation. Transformation was obtained with the plasmid pAN7–1 carrying a bacterial hygromycin resistance gene as a selectable marker under the control ...

Genetic Improvement of Biocontrol Agents for Sustainable Pest Management
2014Genetic improvement involves directed purposeful genetic alterations to enhance the efficacy of natural enemies for biological control. This may be achieved by conventional approaches as well as through recombinant DNA techniques. The conventional methods include strain selection, serial passage through hosts, mutation, conjugation, transduction ...

Investigating the potential of X shredding for mouse genetic biocontrol
2023AbstractCRISPR-Cas9 technology has facilitated development of strategies that can potentially provide more humane and effective methods to control invasive vertebrate species, such as mice. One promising strategy is X chromosome shredding which aims to bias offspring towards males, resulting in a gradual and unsustainable decline of females.

Current Opinion in Biotechnology, 2000
Root diseases caused by fungal pathogens can be suppressed by certain rhizobacteria that effectively colonize the roots and produce extracellular antifungal compounds. To be effective, biocontrol bacteria need to be present at sufficiently high cell densities.

Genetically Engineered Microbial Agents for Biocontrol of Plant Fungal Diseases
2005The objectives of the project were: a) to construct the site-specific integrative expression cassettes carrying: (i) the chiA gene for a 58-kDa endochitinase, (ii) the pyrrolnitrin biosynthesis operon, and (iii) the acdS gene encoding ACC deaminase; b) to employ these constructs to engineer stable recombinant strains with an expanded repertoire of ...

Re-evaluation of biosafety questions on genetically modified biocontrol bacteria
European Journal of Plant Pathology, 2018Microorganisms have the potential to promote plant health and can be used to increase agricultural production that depends less on chemical control. The implementation of EU Directive 2009/128/EC, also called the Sustainable Use Directive, has led to a renewed interest in microbial biocontrol of plant diseases.
