Dominant resistance against plant viruses
To establish a successful infection plant viruses have to overcome a defense system composed of several layers. This review will overview the various strategies plants employ to combat viral infections with main emphasis on the current status of single dominant resistance (R) genes identified against plant viruses and the corresponding avirulence (Avr) genes identified so far. The most common m...
متن کاملSources of natural resistance to plant viruses: status and prospects.
SUMMARY Globally, virus diseases are common in agricultural crops and have a major agronomic impact. They are countered through the deployment of genetic resistance against the virus, or through the use of a range of farming practices based upon the propagation of virus-free plant material and the exclusion of the virus vectors from the growing crop. We review here the current status of our kno...
متن کاملStability of Transgenic Resistance Against Plant Viruses
Plant viruses constitute one of the main problems of the agricultural production worldwide (Kang et al., 2005). To date, there are not therapeutical measures available for the control of plant-virus diseases in the field and the main control strategy used in practice is based on prevention measures. Genetic resistance is by far the most effective way to control plant viruses. However, ‘traditio...
متن کاملStrategies to protect crop plants against viruses: pathogen-derived resistance blossoms.
Since 1986, the ability to confer resistance against an otherwise devastating virus by introducing a single pathogen-derived or virus-targeted sequence into the DNA of a potential host plant has had a marked influence on much of the research effort, focus, and short-term objectives of plant virologists throughout the world. The vast literature on coat protein-mediated protection, for example, a...
متن کاملMechanisms of Pathogen-Derived Resistance to Viruses in Transgenic Plants.
In 1985, Sanford and Johnston developed the simple and elegant concept of parasiteor pathogen-derived resistance (Sanford and Johnston, 1985). Subsequently, there have been numerous attempts to generate virus resistance in transgenic plants based on this concept through the expression of virusderived genes or genome fragments (Beachy, 1993; Wilson, 1993; Baulcombe, 1994b; Lomonossoff, 1995). Ma...
