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.

Dual phenazine gene clusters enable diversification during biosynthesis.

TL;DR: Evaluation of the antibiotic activity of the resulting phenazine derivatives suggests a highly effective strategy to convert Gram-positive specific phenazines into broad-spectrum antibiotics, which might help the bacteria–nematode complex to maintain its special environmental niche.

Molecular phylogeny and evolution of red algal parasites: a case study of Benzaitenia, Janczewskia, and Ululania (Ceramiales).

TL;DR: P phylogenetic analyses of red algal parasites commonly found in the Northwestern Pacific and the Hawaiian Islands suggest that J. hawaiiana and U. stellata have likely evolved from species other than their current hosts and have switched hosts at some point in their evolutionary history.

The scale and evolutionary significance of horizontal gene transfer in the choanoflagellate Monosiga brevicollis

TL;DR: The results suggest that HGT is frequent in Monosiga brevicollis and might have contributed substantially to its adaptation and evolution, and highlights the importance of HGT in the genome and organismal evolution of phagotrophic eukaryotes.

Horizontal transfer of a subtilisin gene from plants into an ancestor of the plant pathogenic fungal genus Colletotrichum.

TL;DR: The phylogenetic analysis indicates that the HGT event would have occurred approximately 150–155 million years ago, after the divergence of the Colletotrichum lineage from other fungi, and it is postulate that the CPLSs have an important role in plant infection.

Molecular evolution of glutamine synthetase II: Phylogenetic evidence of a non-endosymbiotic gene transfer event early in plant evolution

TL;DR: Phylogenetic evidence suggests GSIIB in Chloroplastida evolved by HGT, possibly after the divergence of the primary endosymbiotic lineages, and the isoenzymes may have evolved via different evolutionary processes.

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.
