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.read more

Prokaryotic ancestry and gene fusion of a dual localized peroxiredoxin in malaria parasites
Carine F. Djuika,Jaime Huerta-Cepas,Jude M. Przyborski,Sophia Deil,Cecilia P. Sanchez,Tobias Doerks,Peer Bork,Michael Lanzer,Marcel Deponte +8 more
TL;DR: It is shown that apicomplexan homologues of peroxiredoxin 5 (Prx5) have a prokaryotic ancestry and therefore represent a special subclass of Prx5 isoforms in eukaryotes, and phylogenetic analyses contradict an acquisition by secondary endosymbiosis and support a gene fusion event following a horizontal proKaryote-to-eukaryote gene transfer in early apicOMplexans.

Duplication and expression of horizontally transferred polygalacturonase genes is associated with host range expansion of mirid bugs.
TL;DR: It is suggested that polygalacturonase genes are more strictly required by phytozoophagous than by zoophytophagously mirid bugs and that the duplication of PGs is associated with the expansion of host plant ranges in mirid Bugs.

Evidence of prokaryote like protein associated with nickel resistance in higher plants: horizontal transfer of TonB-dependent receptor/protein in Betula genus or de novo mechanisms?
G Theriault,K K Nkongolo +1 more
TL;DR: The results from next generation sequencing and RT-qPCR analyses show that genes involved in transport activities are upregulated in nickel-resistant genotypes compared with susceptible forms, and suggest that the TonB-dependent receptor may be exclusive to the Betula genus.

Identification of novel phospholipase A2 group IX members in metazoans.
TL;DR: Observations support the idea of the common evolutionary origin of GXIV and GIX PLA2 pfam09056 members, which emerged early in bacteria and were maintained in the genomes of fungi and selected extant metazoan taxa.

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.
