Horizontal gene transfer of the Pytheas sequence from Cuscuta to Orobanche via a host-mediated pathway Open
Horizontal Gene Transfer (HGT) is a phenomenon of DNA transfer between organisms that does not involve a parent-offspring relationship. HGT is believed to play an important role in all groups of organisms, including plants, and especially …

Photosynthetic activity in the heterotrophic plant genus <i>Cuscuta</i> (Convolvulaceae) is modulated by phylogeny and ontogeny Open
Background and Aims Photosynthesis is central to plant function, yet it has been repeatedly lost or diminished in parasitic angiosperm lineages. This variation raises questions about how photosynthetic function is retained, modified or rep…

Mitochondrial Phylogenomics of <i>Cuscuta</i> (Convolvulaceae) Reveals a Potentially Functional Horizontal Gene Transfer from the Host Open
Horizontal gene transfers (HGTs) from host or other organisms have been reported in mitochondrial genomes of parasitic plants. Genes transferred in this fashion have usually been found nonfunctional. Several examples of HGT from the mitoch…
