Nature Rev Microbiol: Hypovirulence: Mycoviruses at the fungal-plant interface

Nature Rev Microbiol: Hypovirulence: Mycoviruses at the fungal-plant interface | biotech-translations | Scoop.it

Whereas most mycoviruses lead 'secret lives', some reduce the ability of their fungal hosts to cause disease in plants. This property, known as hypovirulence, has attracted attention owing to the importance of fungal diseases in agriculture and the limited strategies that are available for the control of these diseases. Using one pathogen to control another is appealing, both intellectually and ecologically. The recent development of an infectious cDNA-based reverse genetics system for members of the Hypoviridae mycovirus family has enabled the analysis of basic aspects of this fascinating virus–fungus–plant interaction, including virus–host interactions, the mechanisms underlying fungal pathogenesis, fungal signalling pathways and the evolution of RNA silencing. Such systems also provide a means for engineering mycoviruses for enhanced biocontrol potential.

The last 20 years have provided a sophisticated understanding of how plants recognize relatively conserved microbial patterns to activate defence. This workshop will cover broad aspects of the plant-microbe interaction and train methods to study and visualise intracellular interactions during pathogenesis and defence.

Many plant species acquire a significant amount of their nutritional needs through symbiotic interactions with micro-organisms. The work in this laboratory focuses on two symbiotic interactions of legumes: the mycorrhizal association that aids in the uptake of nutrients from the soil and is particularly important for plant acquisition of phosphates and the rhizobial symbiosis that provides a source of nitrogen to the plant. In both cases the establishment of these interactions involves a molecular communication between the plant and the micro-organisms, with diffusible signals being released by both the mycorrhizal fungi and the rhizobial bacteria.

 

Our work is focused on understanding how legumes perceive these diffusible signals and transduce this information for the activation of developmental processes associated with accommodating these symbionts.
