Whole-genome duplication and molecular evolution in Cornus L. (Cornaceae) - Insights from transcriptome sequences.

ABSTRACT: The pattern and rate of genome evolution have profound consequences in organismal evolution. Whole-genome duplication (WGD), or polyploidy, has been recognized as an important evolutionary mechanism of plant diversification. However, in non-model plants the molecular signals of genome duplications have remained largely unexplored. High-throughput transcriptome data from next-generation sequencing have set the stage for novel investigations of genome evolution using new bioinformatic and methodological tools in a phylogenetic framework. Here we compare ten de novo-assembled transcriptomes representing the major lineages of the angiosperm genus Cornus (dogwood) and relevant outgroups using a customized pipeline for analyses. Using three distinct approaches, molecular dating of orthologous ge
