Plant translational genomics: from model species to crops

Abstract

Plant genomic research now faces the ultimate challenge to develop applications in crop plants which implies the translation of gene functions from a model to a crop which is the field of ‘Plant translational genomics’. In this paper we discuss the perspectives of the candidate gene approach (CGA) as a tool for translational genomics in the ‘whole genome’ era. Factors to be considered for a successful application of the CGA in crops such as the type of crop, the complexity of the trait and the type of genes involved are discussed. Several crop traits that require improvement such as tolerance to stress, pod shatter in Brassicaceae and Fusarium resistance, are evaluated with regard to the potential of a CGA as a tool for crop improvement
