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.

Role of horizontal gene transfer in the evolution of photosynthetic eukaryotes and their plastids.

TL;DR: The proteome of many plastids has emerged as a mosaic of proteins from many sources, some from within the same cell (e.g., cytosolic genes or genes left over from the replacement of an earlier plastid), some from thePlastid of other algal lineages, and some from completely unrelated sources.

Phylogenomic study indicates widespread lateral gene transfer in Entamoeba and suggests a past intimate relationship with parabasalids.

TL;DR: The approach, using an automated phylogenomic pipeline to build taxon-rich gene trees, suggests that LGT is more extensive than previously thought and provides evidence of a common sister relationship between genes of Entamoeba (Amoebozoa) and parabasalids (Excavata).

Evolving Graphs by Graph Programming

TL;DR: This work proposes an approach to exploiting the power of graph programming as a representation and as an execution medium in an evolutionary algorithm (EGGP), and demonstrates this power in comparison with Cartesian Genetic Programming (CGP), showing that it is significantly more efficient in terms of fitness evaluations on some classic benchmark problems.

Diversity and origin of carotenoid biosynthesis: its history of coevolution towards plant photosynthesis.

TL;DR: In this article, the evolution of carotenoid pathways in relation to the functionality of the resulting structures in photosynthesis is the focus of a review, which is a result of gene acquisition, including their functional modifications, emergence of novel genes and gene exchange between species.

Nitrile Hydratase Genes Are Present in Multiple Eukaryotic Supergroups

TL;DR: The evidence presented here demonstrates that nitrile hydratase genes are present in multiple eukaryotic supergroups, suggesting that a subunit fusion gene was present in the last common ancestor of all eukARYotes.

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.
