Detection and Phylogenetic Assessment of Conserved Synteny Derived from Whole Genome Duplications [chapter]

Shigehiro Kuraku, Axel Meyer
2012 Msphere  
Identification of intragenomic conservation of gene compositions in multiple chromosomal segments led to evidence of whole genome (WGDs) duplications.  ...  The process by which WGDs have been maintained and decayed provides us with clues for understanding how the genome evolves.  ...  Whether a new duplicate arose in a small-scale event (for example, tandem duplication) or large-scale event (for example, WGD), the fate of the new duplicate largely depends on the pattern in functional  ...
