TLDR
The number of well-supported cases of transfer from both prokaryotes and eukaryotes, many with significant functional implications, is now expanding rapidly and major recent trends include the important role of HGT in adaptation to certain specialized niches and the highly variable impact of H GT in different lineages.
Abstract
Horizontal gene transfer (HGT; also known as lateral gene transfer) has had an important role in eukaryotic genome evolution, but its importance is often overshadowed by the greater prevalence and our more advanced understanding of gene transfer in prokaryotes. Recurrent endosymbioses and the generally poor sampling of most nuclear genes from diverse lineages have also complicated the search for transferred genes. Nevertheless, the number of well-supported cases of transfer from both prokaryotes and eukaryotes, many with significant functional implications, is now expanding rapidly. Major recent trends include the important role of HGT in adaptation to certain specialized niches and the highly variable impact of HGT in different lineages.

Symbiodinium transcriptomes: genome insights into the dinoflagellate symbionts of reef-building corals.

TL;DR: In this paper, the authors used 454 sequencing to generate transcriptome data from two Symbiodinium species from different clades (clade A and clade B) with more than 56,000 assembled sequences per species, these data represent the largest transcriptomic resource for dinoflagellates to date.

Insights into the Evolution of Vitamin B12 Auxotrophy from Sequenced Algal Genomes

TL;DR: Investigating elements of B(12) metabolism in the sequenced genomes of 15 different algal species, with representatives of the red, green, and brown algae, diatoms, and coccolithophores, including both macro- and microalgae, and from marine and freshwater environments found a strong correlation between the absence of a functional METE gene and B( 12) auxotrophy.

Horizontal gene transfer facilitated the evolution of plant parasitic mechanisms in the oomycetes

TL;DR: Using whole-genome, gene-by-gene phylogenetic analysis, an extensive pattern of cross-kingdom HGT between fungi and oomycetes is demonstrated, consistent with the hypothesis that some oomyCetes became successful plant parasites by multiple acquisitions of genes from fungi.

TACOA: taxonomic classification of environmental genomic fragments using a kernelized nearest neighbor approach.

TL;DR: An accurate multi-class taxonomic classifier was developed for environmental genomic fragments TACOA, which can predict with high reliability the taxonomic origin of genomic fragments as short as 800 bp.

Endosymbiotic associations within protists.

TL;DR: Endosymbiosis seems to represent a general evolutionary strategy of protists to acquire novel biochemical functions and is thus an important source of genetic innovation.

Lateral gene transfer and the nature of bacterial innovation

TL;DR: Unlike eukaryotes, which evolve principally through the modification of existing genetic information, bacteria have obtained a significant proportion of their genetic diversity through the acquisition of sequences from distantly related organisms.

Genome evolution in yeasts

TL;DR: Analysis of chromosome maps and genome redundancies reveal that the different yeast lineages have evolved through a marked interplay between several distinct molecular mechanisms, including tandem gene repeat formation, segmental duplication, a massive genome duplication and extensive gene loss.

Phylogenetic Classification and the Universal Tree

TL;DR: Molecular phylogeneticists will have failed to find the “true tree,” not because their methods are inadequate or because they have chosen the wrong genes, but because the history of life cannot properly be represented as a tree.
