Genomics Approaches for Crop Improvement against Abiotic Stress

Figure 1

Functional, structural, and comparative genomics approaches are highly interrelated. For example, microarrays can be used either to anchor markers to genome maps or to analyze gene expression; functional markers indicate both phenotypes and genetic locations; QTL-seq utilizes a reference genome sequence to isolate QTLs based on phenotypic variation. As more structural genomics information becomes available, comparative genomics tools such as genome zippers can be used both to elucidate the structure of unsequenced genomes and as a shortcut to design targeted functional studies.
