PhD Project: Development of sequence capture to study whole genome duplication in salmonids (Viva: August 2017)
My NERC funded PhD project aimed to develop a targeted sequence capture approach to obtain a large set of protein-coding genes across all genera of the salmonid fish family. The sequence capture approach was applied to obtain thousands of gene duplicates conserved from a salmonid-specific whole genome duplication (WGD) event (Lappin et al. 2016; Robertson et al. 2017). This has allowed high resolution evolutionary reconstructions of the role of WGD in salmonid genome evolution, including the validation of the 'lineage-specific ohnologue resolution' (LORe) model (Robertson et al. 2017), which is linked to delayed rediploidization post-WGD. I also used the sequence capture data to characterize the role of WGD in the expansion and diversification of salmonid gene families, including from the insulin-like growth factor system (Lappin et al. 2016), as well as the Hox clusters (Robertson et al. 2017).
