“…In vitro selection was quickly embraced by plant pathologists and plant breeders alike to select for resistance to plant pathogens producing toxins involved in pathogenesis (for reviews see Buiatti and Ingram 1991;Svabova and Lebeda 2005). There has also been an interest over the years in selecting for salt tolerance (e.g., Karadimova and Djambova 1993;Winicov 1996;Zhang et al 2001;Dziadczyk et al 2003;Queiros et al 2007;Hamrouni et al 2008;He et al 2009) and herbicide resistance (e.g., Kinoshita and Mori 1991;Pofelis et al 1992;Baillie et al 1993;Escorial et al 1996;Taregyan et al 2001;Yu et al 2004;Gurel et al 2008) using such culture systems.…”

Plant breeding has had a tremendous influence on crop improvement. However, due to dwindling germplasm resources, identification of variability for incorporation into new cultivars is becoming more difficult. Therefore, there has been recourse to alternative approaches including mutagenesis, tissue culture and genetic transformation to aid breeding programs. Furthermore, with the vast repertoire of genome-wide data from different expression profiling techniques such as microarrays, more subtle understanding of gene expression is being obtained and is further helping plant breeders to entertain a different selection approach based on expression quantitative traits to maximize combinations of genes capable of conferring high performance. In this chapter, we review some of the aspects of plant breeding and the influence functional genomics has on breeding programs. Some of the challenges to functional genomics and breeding come from establishment of high-throughput transformation systems to assess gene function, which is limiting functional characterization of numerous genes in their respective crops. Therefore, this chapter also focuses on the need to gain better understanding of the development of gene transfer systems for crop plants to make use of the array of available gene information data.
