Role of Strigolactones in the Host Specificity of Broomrapes and Witchweeds

Plant And Cell Physiology, 2023
AbstractRoot parasitic plants of the Orobanchaceae, broomrapes and witchweeds, pose a severe problem to agriculture in Europe, Asia and especially Africa. These parasites are totally dependent on their host for survival, and therefore, their germination is tightly regulated by host presence.

2D and 3D visualization of herbaceous plant–plant contact zones using high‐resolution X‐ray computed tomography (HRXCT)

PLANTS, PEOPLE, PLANET, Volume 7, Issue 2, Page 367-381, March 2025.
Parasitic plants that deprive crops of water and nutrients are an increasingly concerning food security issue, affecting the livelihood of millions of subsistence, small‐ and mid‐scale farmers. An in‐depth understanding of parasite–host interactions is required to develop species‐specific and ecologically sustainable parasite management methods.

Influence of Alectra vogelii inoculation and phosphorus fertilizer application on phenology, yield components and grain yield of bambara groundnut genotypes

Heliyon
In sub-Saharan Africa, the parasitic Alectra vogelii is seriously threatening Bambara groundnuts, farmers to suffer yield losses of up to 100 %. The objective of this study was to determine the effects of phosphorus (P) application and Alectra vogelii ...

Geographical distribution and aspects of the ecology of the hemiparasitic angiosperm Striga asiatica (L) Kuntze: A herbarium study [PDF]

, 1997
Striga asiatica (Scrophulariaceae) is an obligate root hemiparasite of mainly C-4 grasses (including cereals). It is the most widespread of the 42 Striga species occurring in many semi-tropical, semi-arid regions of mainly the Old World.

The role of strigolactone structural diversity in the host specificity and control of Striga, a major constraint to sub‐Saharan agriculture

PLANTS, PEOPLE, PLANET, Volume 7, Issue 2, Page 318-330, March 2025.
The parasitic weed Striga affects crops such as sorghum, maize, millet, and rice in over 40 countries on the African continent and negatively impacts the livelihood of over 300 million small‐holder farmers. Striga seeds can remain dormant in the soil for many years until they are triggered to germinate by germination stimulants, called strigolactones ...

Parasitic plants are models for examining global food security, biodiversity loss and host–parasite evolution, in a changing world

PLANTS, PEOPLE, PLANET, Volume 7, Issue 2, Page 303-307, March 2025.
Parasitic plants, though often overlooked, are of exceptional importance and play a major functional role in the world's ecosystems. Where parasitic plants affect agricultural systems, they pose a threat to global food security at a time when this is already foreshadowed by a fast‐changing climate, a growing human population, economic volatility and ...

Multiple layers of incompatibility to the parasitic witchweed, Striga hermonthica [PDF]

New Phytologist, 2009
* Witchweeds (Striga spp.) are major agricultural pests that infest important crops in sub-Saharan Africa. Striga hermonthica parasitizes gramineous plants including sorghum, maize and rice, but not dicots. To understand host recognition mechanisms of S.

Cytokinins as an alternative suicidal Striga germination compound

Weed Research, Volume 65, Issue 2, March/April 2025.
Abstract The witchweed Striga hermonthica, an obligate and noxious root–parasitic plant, remains a persistent threat to cereal production and poses a great challenge to smallholder farmers in Sub‐Saharan Africa. Inducing suicidal germination of Striga seeds by applying strigolactone analogs is a promising strategy to deplete the Striga seed bank of ...
