Convergent Plastome Evolution and Gene Loss in Holoparasitic Lennoaceae

Genome Biology and Evolution, 2018
The Lennoaceae, a small monophyletic plant family of root parasites endemic to the Americas, are one of the last remaining independently evolved lineages of parasitic angiosperms lacking a published plastome. In this study, we present the assembled and annotated plastomes of two species spanning the crown node of Lennoaceae, Lennoa madreporoides and ...

Reading between the vines: Hosts as islands for extreme holoparasitic plants [PDF]

American Journal of Botany, 2017
PREMISE OF THE STUDY:Partitioning of population genetic variation in plants may be affected by numerous factors including life history and dispersal characteristics. In parasitic plants, interactions with host populations may be an additional factor influencing partitioning.

The evolution of the plastid genomes in the holoparasitic Balanophoraceae

Proceedings of the Royal Society B: Biological Sciences
The independent transition to a heterotrophic lifestyle in plants drove remarkably convergent evolutionary trajectories, characterized by morphological modifications and reductions in their plastomes. The characteristics of the minimum plastome required for survival, if they exist, remain a topic of debate. The holoparasitic family

Orobanche crenata control in three faba bean varieties by soaking seeds in acetylsalicylate solutions [PDF]

Journal of Crop Protection
The prevalence of Orobanche crenata on faba bean fields in the Mediterranean region is a serious problem. The chemical inducers, including salicylic acid and its analogues were reported to activate the systemic acquired resistance in plants to subsequent

Unique phytochrome responses of the holoparasitic plant Orobanche minor [PDF]

New Phytologist, 2009
Holoparasitic plants such as Orobanche spp. have lost their photosynthetic ability, so photoresponses to optimize photosynthesis are not necessary in these plants. Photoresponses are also involved in the regulation of plant development but the photoresponses of holoparasites have not been characterized in detail.

Crip21-alert from dodder to crops [PDF]

, 2020
Together with pathogenic microbes and herbivorous insects, parasitic plants are emerging as aggressive threats on agriculture worldwide. Among them, Cuscuta (dodder), a stem holoparasite, extracts nutrients and water from host plants through phloem ...

A New Genus of Holoparasitic Orobanchaceae from Mexico

Novon: A Journal for Botanical Nomenclature, 2009
We describe here a novel achlorophyllous parasite on the roots of Hedyosmum mexicanum C. Cordemoy (Chloranthaceae) as a new genus and species, Eremitilla mexicana Yatskievych & J. L. Contreras. The new taxon is currently thought to be endemic to the state of Guerrero, Mexico. It is best classified in the Orobanchaceae, but differs from other members of

Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations?

Plant, Cell &Environment, EarlyView.
ABSTRACT Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization.
