Anatomy of the roots of some northern hemiparasites (Orobanchaceae)

open access: yesTurczaninowia, 2017
The root structure and the haustorial formation of 5 northern hemiparasites: Bartsia alpina, Castilleja lapponica, Pedicularis lapponica, Pedicularis sceptrum-carolinum, Rhinanthus minor subsp. groenlandicus (Orobanchaceae) have been studied.

Complete chloroplast genomes of the hemiparasitic genus Cymbaria: Insights into comparative analysis, development of molecular markers, and phylogenetic relationships [PDF]

open access: yesEcology and Evolution
The hemiparasitic tribe Cymbarieae (Orobanchaceae) plays a crucial role in elucidating the initial stage of the transition from autotrophism to heterotrophism. However, the complete chloroplast genome of the type genus Cymbaria has yet to be reported. In

Spatial patterns and policy implications of invasive flora in the Horn of Africa [PDF]

open access: yesScientific Reports
Invasive plants are fast-spreading species that pose serious and often irreversible threats to native biodiversity. This study presents a regional-scale analysis of the elevational distribution of invasive plant species, their relationship with road ...

Parasitism modifies the direct effects of warming on a hemiparasite and its host. [PDF]

open access: yesPLoS ONE, 2019
Climate change is affecting interactions among species, including host-parasite interactions. The effects of warming are of particular interest for interactions in which parasite and host physiology are intertwined, such as those between parasitic plants

Nitrogen enrichment reduces parasitism in an annual hemiparasite. [PDF]

open access: yesAm J Bot
AbstractPremiseAnthropogenic activities such as fossil fuel combustion and synthetic fertilizer synthesis have resulted in nitrogen (N) deposition and elevated N availability in ecosystems. Many parasitic plants are adapted to low N environments and have evolved mechanisms to sequester water, N, and other limiting nutrients from hosts.

Effects of abiotic factors on hemiparasitic plants

open access: yes, 2018
This thesis focuses on the ecophysiology of hemiparasitic plants. In its introduction, I review our understanding of abiotic factor effects on root and stem hemiparasites and highlight gaps in our knowledge which would be interesting to explore in future.

Distribution patterns and influencing factors of different parasitic angiosperm types in China

open access: yesGlobal Ecology and Conservation, 2021
Parasitic plants are widely distributed in major biomes. They can be categorized into root parasites and stem parasites in terms of parasitic sites or divided into hemiparasites and holoparasites according to the degree of nutritional dependence on their

Evaluating the Multi-level Community Effects of Root Hemiparasites in Northern Illinois [PDF]

open access: yes, 2021
Root hemiparasites are green plants that tap into a neighboring plant’s water-filled xylem to acquire inorganic nutrients, which can lead to an accumulation of nutrients in hemiparasite biomass.

Knowledge Gaps in Taxonomy, Ecology, Population Distribution Drivers and Genetic Diversity of African Sandalwood (Osyris lanceolata Hochst. & Steud.): A Scoping Review for Conservation

open access: yesPlants, 2021
The increasing demand for ornamental, cosmetic and pharmaceutical products is driving exploitation of plant species globally. Sub-Saharan Africa harbours unique and valuable plant resources and is now a target of plant resource depletion.

Plastome Evolution in Hemiparasitic Mistletoes [PDF]

open access: yesGenome Biology and Evolution, 2015
Santalales is an order of plants consisting almost entirely of parasites. Some, such as Osyris, are facultative root parasites whereas others, such as Viscum, are obligate stem parasitic mistletoes. Here, we report the complete plastome sequences of one species of Osyris and three species of Viscum, and we investigate the evolutionary aspects of ...
