Systemic gene silencing in Arabidopsis, and relevance to plant biology. Gene silencing is a highly conserved process in plants and animals. It is of fundamental importance to gene regulation, virus defence, genome response to environment, and genome evolution. Remarkably, when gene silencing is triggered in plants it can spread throughout the organism.

Gene silencing is a highly conserved process in plants and animals. It is of fundamental importance to gene regulation, virus defence, genome response to environment, and genome evolution. Remarkably, when gene silencing is triggered in plants it can spread throughout the organism. The aim of this project is to define the mechanism of intercellular movement of gene silencing in plants, and its relevance to plant growth and defence against pathogens. Expected outcomes include increased understanding of intercellular genetic signalling in plants and its role in plant growth and disease resistance. The findings may also shed new light on mechanisms of gene silencing in animals.Read moreRead less
Mediator: a new concept for controlled gene expression in plant biotechnology. The Mediator protein complex is a new control point for the activation of all genes in higher organisms and the purpose of this project is to understand how three Mediator subunits regulate disease resistance in plants. The outcomes provide a new concept to direct natural gene expression towards robust crop plants able to cope with climatic variations.
