Background The molecular evolution of organellar genomes in angiosperms has been
studied extensively, with some lineages, such as parasitic ones, displaying unique …

Convolvulaceae is a family of c. 2,000 species, distributed across 60 currently recognized
genera. It includes species of high economic importance, such as the crop sweet potato …

The mitochondrial genome of Liriodendron tulipifera exhibits many ancestral angiosperm
features and a remarkably slow evolutionary rate, while mitochondrial genomes of other …

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 …

Gastrodia pubilabiata is a nonphotosynthetic and mycoheterotrophic orchid belonging to
subfamily Epidendroideae. Compared to other typical angiosperm species, the plastome of …

Background Mycoheterotrophs, acquiring organic carbon and other nutrients from
mycorrhizal fungi, have evolved repeatedly with substantial plastid genome (plastome) …

Main conclusion Most species in Cuscuta subgenus Grammica retain many photosynthesis-
related plastid genes, generally under purifying selection. A group of holoparasitic species …

Parasitic lifestyle can often relax the constraint on the plastome, leading to gene
pseudogenization and loss, and resulting in diverse genomic structures and rampant …

Epipogium roseum, commonly known as one of the ghost orchids due to its rarity and almost
transparent color, is a non-photosynthetic and fully mycoheterotrophic plant. Given its …

Distinct hosts have been hypothesized to possess the potential for affecting species
differentiation and genome evolution of parasitic organisms. However, what host shift history …
