Genes have transferred from a crop plant to an evolutionarily divergent parasitic weed. Horizontal gene transfer has been postulated to occur between crops to co-occurring parasitic plants, but empirical evidence has been lacking. We present evidence that an HGT event moved a nuclear monocot gene into the genome of the eudicot parasite witchweed (Striga hermonthica), which infects many grass species in Africa. Analysis of expressed sequence tags revealed that the genome of S. hermonthica… 
Horizontal gene transfer in parasitic plants.
Evolution of a horizontally acquired legume gene, albumin 1, in the parasitic plant Phelipanche aegyptiaca and related species
TLDR
The HGT-derived albumins in Phelipanche represent a novel example of how plants can acquire genes from other plants via HGT that then go on to duplicate, evolve, and retain the specialized features required to perform a unique host-derived function.
Widespread impact of horizontal gene transfer on plant colonization of land
TLDR
It is shown that horizontal gene transfer is a dynamic process occurring frequently in the early evolution of land plants, and a model of horizontal gene Transfer mechanism in nonvascular and seedless vascular plants is proposed.
Footprints of parasitism in the genome of the parasitic flowering plant Cuscuta campestris
TLDR
The authors describe the genome sequence of a parasitic plant, Cuscuta campestris, and find that gene losses and host gene acquisitions reflect the independence from photosynthesis and the ability to retain and express chunks of foreign genomic DNA.
Root parasitic plant Orobanche aegyptiaca and shoot parasitic plant Cuscuta australis obtained Brassicaceae-specific strictosidine synthase-like genes by horizontal gene transfer
TLDR
This study strongly supports that parasitic plants can gain novel nuclear genes from distantly related host species by HGT and the foreign genes may execute certain functions in the new hosts.
Horizontal transfer of expressed genes in a parasitic flowering plant
TLDR
The results establish for the first time a substantive number of HGTs in a plant host-parasite system, and the elevated rate of unidirectional host-to- parasite gene transfer raises the possibility that H GTs may provide a fitness benefit to Rafflesia for maintaining these genes.
Massive Mitochondrial Gene Transfer in a Parasitic Flowering Plant Clade
TLDR
This study is the first to comprehensively assess the magnitude of HGT in plants involving a genome and a species interaction where it has been hypothesized to be potentially rampant, and indicates that HGT involving mitochondrial genes is substantially higher than previously thought.
Horizontal gene transfer in the innovation and adaptation of land plants
TLDR
This paper categorizes all acquired genes based on their putative functions and biological processes, and further addresses the importance of HGT in plant innovation and evolution.
Phylogenetic relatedness, co-occurrence, and rhizomes increase lateral gene transfer among grasses
TLDR
It is shown that LGT is a widespread phenomenon in grasses, which is boosted by repeated contact among related lineages and compatibility, and appears to be dependent on both opportunity and compatibility.

A full-length enriched cDNA library and expressed sequence tag analysis of the parasitic weed, Striga hermonthica
TLDR
The authors' data provide the first extensive set of molecular resources for studying S. hermonthica, and include EST sequences, a comparative analysis with other plant genomes, and useful genetic markers that will be useful for genome annotation, gene discovery, functional analysis, molecular breeding, epidemiological studies, and studies of plant evolution.
Horizontal gene transfer in eukaryotic evolution
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.
Phylogeny of the parasitic plant family Orobanchaceae inferred from phytochrome A.
TLDR
The robust phylogenetic hypothesis inferred from the PHYA data provides a much better context in which to evaluate the evolution of parasitism within Orobanchaceae, the largest of the parasitic angiosperm families.
Cyanobacterial contribution to the genomes of the plastid-lacking protists
TLDR
It is demonstrated that a considerable number of genes with cyanobacterial ancestry have contributed to the genome composition of the plastid-lacking protists, especially bikonts.
A rapid bootstrap algorithm for the RAxML Web servers.
TLDR
This work developed, implemented, and thoroughly tested rapid bootstrap heuristics in RAxML (Randomized Axelerated Maximum Likelihood) that are more than an order of magnitude faster than current algorithms and can contribute to resolving the computational bottleneck and improve current methodology in phylogenetic analyses.
Assessment of methods for amino acid matrix selection and their use on empirical data shows that ad hoc assumptions for choice of matrix are not justified
TLDR
It is demonstrated that for two large datasets derived from the proteobacteria and archaea, one of the most favored models in both datasets is a model that was originally derived from retroviral Pol proteins.
