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

Characterisation of a mitochondrial iron transporter of the pathogen Trypanosoma brucei
TL;DR: It is suggested that TbMCP17 functions as a mitochondrial iron transporter in the parasite T. brucei, by complementation studies using MRS3/4-deficient yeast.

dCITE: Measuring Necessary Cladistic Information Can Help You Reduce Polytomy Artefacts in Trees.
TL;DR: The greater the dCITE score the more likely it is that the computed phylogenetic tree will be free of artefactual polytomies, and sequences with high cladistic information produce more consistent trees for the same 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.
