Cytonuclear coevolution in a holoparasitic plant with highly disparate organellar genomes

Plant Molecular Biology, 2022
Contrasting substitution rates in the organellar genomes of Lophophytum agree with the DNA repair, replication, and recombination gene content. Plastid and nuclear genes whose products form multisubunit complexes co-evolve. The organellar genomes of the holoparasitic plant Lophophytum (Balanophoraceae) show disparate evolution.

Host Location and Selection by Holoparasitic Plants

2009
Parasitic and carnivorous plants that adopt a heterotrophic lifestyle encounter novel environmental challenges that are shared with other heterotrophs, such as the need to locate hosts or lure prey and the need to overcome the defenses of their intended victims.

The minicircular and extremely heteroplasmic mitogenome of the holoparasitic plant Rhopalocnemis phalloides

Current Biology, 2022
The plastid and nuclear genomes of parasitic plants exhibit deeply altered architectures,1-13 whereas the few examined mitogenomes range from deeply altered to conventional.14-20 To provide further insight on mitogenome evolution in parasitic plants, we report the highly modified mitogenome of Rhopalocnemis phalloides, a holoparasite in Balanophoraceae.

Evidence for plastome loss in the holoparasitic Mystropetalaceae

New Phytologist
Abstract Plastome loss is an extremely unusual phenomenon in land plants, even for those that lose their photosynthetic ability. To date, evidence for plastome loss has only been presented for two holoparasitic angiosperm lineages: two genera ( Rafflesia and Sapria

Embryology in Helosis cayennensis (Balanophoraceae): Structure of Female Flowers, Fruit, Endosperm and Embryo

Plants, 2019
Helosis cayennensis (Balanophoraceae s.str.) is a holoparasite characterised by aberrant vegetative bodies and tiny, reduced unisexual flowers. Here, we analysed the development of female flowers to elucidate their morpho-anatomy and the historical ...

Observations on Plastid Fine-Structure in the Holoparasitic Angiosperm Epifagus Virginiana

American Journal of Botany, 1980
The ultrastructure of plastids in cortex and phloem parenchyma cells of Epifagus virginiana (L.) Bart. is described. Based upon morphology and content, several distinct plastid types appear to exist. “Tubular” complexes, lipid globules and electron dense inclusions in different arrangements appear to account for the degree of plastid variability.

Arabidopsis thaliana is a susceptible host plant for the holoparasite Cuscuta spec

Planta, 2007
Arabidopsis thaliana and Cuscuta spec. represent a compatible host-parasite combination. Cuscuta produces a haustorium that penetrates the host tissue. In early stages of development the searching hyphae on the tip of the haustorial cone are connected to the host tissue by interspecific plasmodesmata.

A COMPARISON OF THE MINERAL RELATIONS OF A HALOPHYTIC HEMIPARASITE AND HOLOPARASITE

Acta Botanica Neerlandica, 1986
The mineral relations of the halophytic root hemiparasite Odontites verna ssp. serotina and stem holoparasite Cuscuta salina var. major were compared. The xylem hemiparasite Odontites occurs on the upper parts of Dutch Wadden salt marshes attached to the roots of salt excluding monocotyledonous plant species. Cuscuta was sampled in San Francisco Bay (U.
