Strategies for map-based cloning of disease resistance genes have been previously reviewed (e. g. Michelmore et al., 1993). In this chapter, we will discuss the recent progress and current limitations with particular emphasis on our efforts to clone and characterize genes for resistance to downy mildew in lettuce. The approaches discussed here are applicable to cloning the determinants of any trait for which only the genetics is known and the species has not been studied intensively at the molecular level.
