TLDR
Sequence-level studies on model organisms whose genomes show clearer evidence of ancient polyploidy are invaluable because they indicate what the evolutionary products of genome duplication can look like.
Abstract
Thirty years after Susumu Ohno proposed that vertebrate genomes are degenerate polyploids, the extent to which genome duplication contributed to the evolution of the vertebrate genome, if at all, is still uncertain. Sequence-level studies on model organisms whose genomes show clearer evidence of ancient polyploidy are invaluable because they indicate what the evolutionary products of genome duplication can look like. The greatest mystery is the molecular basis of diploidization, the evolutionary process by which a polyploid genome turns into a diploid one.

Evolution by gene duplication: an update

TL;DR: Detailed molecular characterization of individual gene families, computational analysis of genomic sequences and population genetic modeling can all be used to help uncover the mechanisms behind the evolution by gene duplication.

Genome duplication in the teleost fish Tetraodon nigroviridis reveals the early vertebrate proto-karyotype

TL;DR: Genome analysis provides a greatly improved fish gene catalogue, including identifying key genes previously thought to be absent in fish, and reconstructs much of the evolutionary history of ancient and recent chromosome rearrangements leading to the modern human karyotype.

The snail superfamily of zinc-finger transcription factors.

TL;DR: The Snail superfamily of zinc-finger transcription factors is involved in processes that imply pronounced cell movements, both during embryonic development and in the acquisition of invasive and migratory properties during tumour progression.

The genome sequence of the filamentous fungus Neurospora crassa

James E. Galagan, +77 more
- 24 Apr 2003 - 
TL;DR: A high-quality draft sequence of the N. crassa genome is reported, suggesting that RIP has had a profound impact on genome evolution, greatly slowing the creation of new genes through genomic duplication and resulting in a genome with an unusually low proportion of closely related genes.

The amphioxus genome and the evolution of the chordate karyotype

TL;DR: Whole-genome comparisons illuminate the murky relationships among the three chordate groups (tunicates, lancelets and vertebrates), and allow not only reconstruction of the gene complement of the last common chordate ancestor but also partial reconstruction of its genomic organization.

TL;DR: Comparative genomic analysis indicates vertebrate expansions of genes associated with neuronal function, with tissue-specific developmental regulation, and with the hemostasis and immune systems are indicated.

Analysis of the genome sequence of the flowering plant Arabidopsis thaliana.

TL;DR: This is the first complete genome sequence of a plant and provides the foundations for more comprehensive comparison of conserved processes in all eukaryotes, identifying a wide range of plant-specific gene functions and establishing rapid systematic ways to identify genes for crop improvement.
