What will change is the methodology by which we select and incorporate exotic germplasm regardless of the end purpose. Transgenic cultivars have been the most visible products of biotechnology but emerging technologies are providing new tools that will allow us to better exploit intraspecific diversity. Germplasm collections are more than gene banks; they are also genotype banks. Preservation of desirable gene combinations that have evolved over centuries of natural selection is important. Microarrays will allow us to identify and assess the importance of these genetic interactions as they relate to plant response to pathogen infection. Accurate phenotypic classification of plant reactions to pathogens may become the most limiting factor in the genetics of host plant resistance. |
