Allele Re-sequencing Technologies

The development of next-generation sequencing technologies has made sequencing an affordable approach for detection of genetic variations associated with various traits. However, the cost of whole genome re-sequencing still remains too high to be feasible for many plant species with large and complex genomes. Recent developments in strategies for target-enrichment, transcriptome re-sequencing, and partial genome re-sequencing allows for enrichment for regions of interest at a scale that is matched to the throughput of next-generation sequencing platforms, and has emerged as a promising alternative to whole genome re-sequencing to identify causative genetic variations in plants. One challenge, however, will be efficient bioinformatics strategies for data handling and analysis from the increasing amount of sequence information.
