“…(Asteraceae). Moreover, our data suggest the occurrence of a second HGT event from Asteraceae to Phelipanche, and confirm that the HGT from hosts to parasites influences mitochondrial genome evolution in the latter (Kwolek et al, 2017).…”

“…It seems that the Orobanche and Phelipanche in the whole range definitely most frequently parasitize species of the Asteraceae family, which is also confirmed by the present study, as well as by data from the western hemisphere (Schneider et al, 2016) and western Asia (Piwowarczyk unpublished). In addition, in our recent work (Kwolek et al, 2017), we demonstrated a host-to-parasite horizontal transfer (HGT) of the mitochondrial atp6 gene in euroasiatic O. coerulescens, which parasitizes Artemisia sp. (Asteraceae).…”

“…The tRNA-Leu (trnL) intron, the partial trnL gene, and the intergenic spacer between the trnL 3' exon and tRNA-Phe (trnF) gene region's plastid DNA (later described as trnL-trnF) were amplified using c and f primers (Taberlet et al, 1991). Both, nuclear and plastid, sequences were amplified as described in Kwolek et al (2017).…”

Holoparasitic genera within the family Orobanchaceae are characterized by greatly reduced vegetative organs; therefore, molecular analysis has proved to be a useful tool in solving taxonomic problems in this family. For this purpose, we studied all species of the genera Orobanche and Phelipanche occurring in Central Europe, specifically in Poland, the Czech Republic, Slovakia, and Austria, supplemented by samples mainly from Spain, France, Germany, and Ukraine. They were investigated using nuclear sequences (ITS region) and a plastid trnL-trnF region. The aim of this study was to examine phylogenetic relationships within Orobanche and Phelipanche from Central Europe; we focused on problematic species and aggregates, recent taxonomic changes in these (rank and secondary ranks), and host ranges. The most interesting results concern the exlusion of O. mayeri from O. alsatica aggr. Additionally, following the rules of traditional taxonomy, the correct names and types of some secondary ranks are given and, as a result of this, a new combination below the Phelipanche genus is made (P. sect. Trionychon). The host ranges of the investigated species in Central Europe include 102 species from 12 families, most often from Asteraceae. For this purpose, ca. 400 localities were examined in the field. Moreover, data acquired from the literature and European and Asian herbaria were used.

“…The complete mitochondrial genome of Orobanchaceae, Castilleja paramensis has been reported [ 23 ], and Zavas et al [ 24 ] reported the mitochondrial genes of two Lathraea species. Genes of the Orobanchaceae plastome and mitogenome, such as atp1 [ 25 ], rpoC2 [ 26 ], atp6 [ 27 ], and nad1 [ 28 ], exhibit several transfers between Orobanchaceae and angiosperms.…”

Orobanchaceae have become a model group for studies on the evolution of parasitic flowering plants, and Aeginetia indica, a holoparasitic plant, is a member of this family. In this study, we assembled the complete chloroplast and mitochondrial genomes of A. indica. The chloroplast and mitochondrial genomes were 56,381 bp and 401,628 bp long, respectively. The chloroplast genome of A. indica shows massive plastid genes and the loss of one IR (inverted repeat). A comparison of the A. indica chloroplast genome sequence with that of a previous study demonstrated that the two chloroplast genomes encode a similar number of proteins (except atpH) but differ greatly in length. The A. indica mitochondrial genome has 53 genes, including 35 protein-coding genes (34 native mitochondrial genes and one chloroplast gene), 15 tRNA (11 native mitochondrial genes and four chloroplast genes) genes, and three rRNA genes. Evidence for intracellular gene transfer (IGT) and horizontal gene transfer (HGT) was obtained for plastid and mitochondrial genomes. ψndhB and ψcemA in the A. indica mitogenome were transferred from the plastid genome of A. indica. The atpH gene in the plastid of A. indica was transferred from another plastid angiosperm plastid and the atpI gene in mitogenome A. indica was transferred from a host plant like Miscanthus siensis. Cox2 (orf43) encodes proteins containing a membrane domain, making ORF (Open Reading Frame) the most likely candidate gene for CMS development in A. indica.

“…Dozens of putative HGT events have been identified across the Orobanchaceae, and many more in other lineages of parasitic angiosperms. However, only rarely are species and gene trees of both parasite and host lineages known with sufficient precision to draw inferences about molecular evolution, historical ecology and historical biogeography, for example the sustained host -parasite association between A. epigalium and its host Galium [10,14,16,45].…”

Punctuated plastome reduction and host–parasite horizontal gene transfer in the holoparasitic plant genus Aphyllon

Foundational studies of chloroplast genome (plastome) evolution in parasitic plants have focused on broad trends across large clades, particularly among the Orobanchaceae, a species-rich and ecologically diverse family of root parasites. However, the extent to which such patterns and processes of plastome evolution, such as stepwise gene loss following the complete loss of photosynthesis (shift to holoparasitism), are detectable at shallow evolutionary time scale is largely unknown. We used genome skimming to assemble eight chloroplast genomes representing complete taxonomic sampling of sect. a small clade within the Orobanchaceae that evolved approximately 6 Ma, long after the origin of holoparasitism. We show substantial plastome reduction occurred in the stem lineage, but subsequent change in plastome size, gene content, and structure has been relatively minimal, albeit detectable. This lends additional fine-grained support to existing models of stepwise plastome reduction in holoparasitic plants. Additionally, we report phylogenetic evidence based on an gene tree and assembled 60+ kb fragments of the mitochondrial genome indicating host-to-parasite horizontal gene transfers (hpHGT) of several genes originating from the plastome of an ancient host into the mitochondrial genome of a recent common ancestor of Ecologically, this evidence of hpHGT suggests that the host-parasite associations between and have been stable at least since its subspecies diverged hundreds of thousands of years ago.
