Abstract

Genetic engineering of crop plants with enhanced disease resistance has offered considerable promise and experimental power, however, with varying degrees of success. Traditional breeding has been very successful, though not in all cases. While the technology for gene manipulation in virtually any crop plant has been available for several years, field success has been hampered by our overall lack of understanding of the essential determinants mediating disease. Two key questions regarding molecular breeding will be addressed: (i) what genes or conceptual approaches can be used that have a realistic chance to be effective? and (ii) can we extrapolate useful information from model plants? Arabidopsis has served as an invaluable model system in many aspects of plant biology, including plant pathology and plant stress physiology, with many insights viewed to be directly applicable to crop plants. In addition, Arabidopsis has several experimental advantages: the genome has been sequenced, microarray chips are available, and there are a multitude of well characterised mutants. In addition, reverse genetics will continue as a powerful tool to examine gene function in Arabidopsis. The pros and cons of Arabidopsis application will be discussed.
