The origin of novel traits is recognized as an important process underlying many major evolutionary radiations. We studied the genetic basis for the evolution of haustoria, the novel feeding organs of parasitic flowering plants, using comparative transcriptome sequencing in three species of Orobanchaceae. Around 180 genes are upregulated during haustorial development following host attachment in at least two species, and these are enriched in proteases, cell wall modifying enzymes, and… Expand
Duplications and Positive Selection Drive the Evolution of Parasitism-Associated Gene Families in the Nematode Strongyloides papillosus
TLDR
This study reveals first insights into the developmental transcriptomes of S. papillosus and provides a detailed analysis of sequence and expression evolution in parasitism-associated gene families. Expand
Large-scale gene losses underlie the genome evolution of parasitic plant Cuscuta australis
TLDR
The authors' analyses reveal that Cuscuta experienced accelerated evolution, and Cus cuta and the convolvulaceous morning glory shared a common whole-genome triplication event before their divergence. Expand
Large-scale gene losses underlie the genome evolution of parasitic plant Cuscuta australis
TLDR
The authors sequence the genome of Cuscuta australis and find remarkable gene loss associated with parasitic lifestyle and large changes in body plan, which is likely result from its parasitic lifestyles and the massive changes of its body plan. Expand
Gene Duplication and Gain in the Trematode Atriophallophorus winterbourni Contributes to Adaptation to Parasitism
TLDR
The de novo sequenced and annotated genome of the parasitic trematode Atriophallophorus winterbourni and its comparative genomic analysis to other major parasitic tre matodes provide a valuable resource for future studies on the genomic basis of adaptation to parasitism and point to specific candidate genes putatively involved in antagonistic host–parasite adaptation. Expand
RNA-seq highlights parallel and contrasting patterns in the evolution of the nuclear genome of fully mycoheterotrophic plants
TLDR
Full heterotrophy leads to profound changes in nuclear gene content and the observed increase in the rate of nucleotide substitutions is lineage specific, rather than a universal phenomenon among non-photosynthetic plants. Expand
Comparative transcriptome analyses of flower development in four species of Achimenes (Gesneriaceae)
TLDR
The floral transcriptomes developed from four species of Achimenes provide insight into the mechanisms involved in the evolution of diverse floral form among closely related species with different pollinators. Expand
Genome Sequence of Striga asiatica Provides Insight into the Evolution of Plant Parasitism
TLDR
The draft genome sequence of Striga asiatica is reported with 34,577 predicted protein-coding genes, which reflects gene family contractions and expansions that are consistent with a three-phase model of parasitic plant genome evolution, and genes involved in lateral root development in non-parasitic model species are coordinately induced during haustorium development in Striga. Expand
RNA-seq highlights parallel and contrasting patterns in the evolution of the nuclear genome of holo-mycoheterotrophic plants
TLDR
The transcriptomes of three species representing two lineages of mycoheterotrophic plants are characterized, finding that Holo-heterotrophy leads to profound changes in nuclear gene content, which is lineage specific, rather than a universal phenomenon among non-photosynthetic plants. Expand
Convergent horizontal gene transfer and cross-talk of mobile nucleic acids in parasitic plants
TLDR
A study identified unprecedented horizontal gene transfer events in Cuscuta campestris and related species, and provides insights into convergent HGTs between Cus cuta and Orobanchaceae parasites and the functional importance of the HGT sequences. Expand
Effector gene birth in plant parasitic nematodes: Neofunctionalization of a housekeeping glutathione synthetase gene
TLDR
The results demonstrate the re-purposing of an endogenous housekeeping gene to form a family of effectors with modified functions, and anticipate that this discovery will be a blueprint to understand the evolution of other plant-parasitic nematode effectors, and the foundation to uncover a novel enzymatic function.

Mitochondrial DNA suggests at least 11 origins of parasitism in angiosperms and reveals genomic chimerism in parasitic plants
TLDR
The results of a phylogenetic analysis of 102 species of seed plants indicate that the parasitic lifestyle has arisen repeatedly in angiosperm evolutionary history and results in increasing parasite genomic chimerism over time. Expand
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. Expand
De Novo Assembly and Characterization of the Transcriptome of the Parasitic Weed Dodder Identifies Genes Associated with Plant Parasitism1[C][W][OPEN]
Transcriptional dynamics during parasitism in the parasitic weed Cuscuta pentagona reveals increased expression of genes encoding transporters and stimulus response regulators, and a decrease in theExpand
Comparative Phylogenomics Uncovers the Impact of Symbiotic Associations on Host Genome Evolution
TLDR
This work presents evidence that loss of AM symbiosis correlates with the loss of many symbiotic genes in the Arabidopsis lineage (Brassicales), and identifies a set of 174 highly conserved genes and demonstrates enrichment in symbiosis-related genes. Expand
Ancestral polyploidy in seed plants and angiosperms
TLDR
Comprehensive phylogenomic analyses of sequenced plant genomes and more than 12.6 million new expressed-sequence-tag sequences from phylogenetically pivotal lineages are used to elucidate two groups of ancient gene duplications, implicating two WGDs in ancestral lineages shortly before the diversification of extant seed plants and extant angiosperms. Expand
Expression pattern shifts following duplication indicative of subfunctionalization and neofunctionalization in regulatory genes of Arabidopsis.
TLDR
Excess divergence specifically indicative of subfunctionalization and/or neofunctionalization contributes to the maintenance of most if not all duplicated regulatory genes in Arabidopsis and it is hypothesized that this results in increasing expression diversity or specificity of regulatory genes after each round of duplication.

Single-Copy Nuclear Genes Place Haustorial Hydnoraceae within Piperales and Reveal a Cretaceous Origin of Multiple Parasitic Angiosperm Lineages
TLDR
The “temporal specialization hypothesis” (TSH) is proposed, implementing multiple independent specialization processes over time during parasitic angiosperm evolution to show the utility of nSCG for reconstructing phylogenetic relationships in parasitic lineages. Expand
Functional genomics of a generalist parasitic plant: Laser microdissection of host-parasite interface reveals host-specific patterns of parasite gene expression
TLDR
De novo assembled transcriptomes generated from laser micro-dissected tissues at the host-parasite interface are compared to uncover details of the largely uncharacterized interaction between parasitic plants and their hosts to suggest T. versicolor's generalist strategy involves a reliance on overlapping but distinct gene sets, depending upon the host plant it is parasitizing.

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. Expand
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. Expand
