Inbred‐Race Recovery From a Mixed Population of the Parasitic Weed Sunflower Broomrape (Orobanche cumana Wallr.)

Weed Research, Volume 66, Issue 1, January/February 2026.
ABSTRACT Sunflower broomrape (Orobanche cumana Wallr.) is a holoparasitic weed with two distinct genetic pools in Spain: the Guadalquivir Valley (GV) and Cuenca province (CU). From a stable situation where races F (FGV and FCU) were predominant, new races have recently emerged: GGV and GCU, presumably caused by population movements and cross ...

Research on resistance to sunflower broomrape: an integrated vision

Oilseeds and fats, crops and lipids, 2016
Sunflower broomrape (Orobanche cumana Wallr.) parasitization on sunflower was first observed at the end of the 19th century and has continued since then jeopardizing sunflower cultivation in many areas of Europe and Asia.

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 ...

Parasitic success of the pathogenic plant Phelipanche ramosa (L.) Pomel. (Orobanchaceae) differs in some re‐infected versus naïve tomato cultivars

Weed Research, Volume 65, Issue 2, March/April 2025.
Abstract Plants are exposed to infection and predation by organisms from most kingdoms of life, including their own. Layers of molecular defence mechanisms have evolved to limit damage and disease from microbial and insect pathogens, and plants can also defend themselves against attack by members of their own kingdom.

Genetic diversity and race composition of sunflower broomrape populations from Tunisia

Phytopathologia Mediterranea, 2018
Sunflower broomrape (Orobanche cumana Wallr.) was detected in 2010 for the first time in sunflower fields of Tunisia, in the Béja region. No information is available on the race composition and genetic diversity of the broomrape populations parasitizing ...

A Blueprint for Building Resilience and Food Security in MENA and SSA Drylands: Diversifying Agriculture With Neglected and Underutilized Species

Food and Energy Security, Volume 14, Issue 1, January/February 2025.
ABSTRACT Drylands, encompassing 41% of global land and supporting over 2 billion people, face significant challenges, including water scarcity, extreme temperatures, and soil degradation. Dryland spans vast areas of Middle East and North Africa (MENA) and Sub‐Sahara Africa (SSA) regions and poses a threat to food security and resilience.

Leveraging time-based spectral data from UAV imagery for enhanced detection of broomrape in sunflower

Smart Agricultural Technology
Sunflower broomrape (Orobanche cumana) poses a severe threat to sunflower crops, parasitizing their roots and hindering plant growth. Current control methods, which typically rely on uniform herbicide applications, are economically inefficient and ...

A potential role of heat‐moisture couplings in the range expansion of Striga asiatica

Ecology and Evolution, Volume 14, Issue 5, May 2024.
Our research examines the effects of climate change on the distribution of parasitic weeds, such as Orobanche, Phelipanche, and Striga, which pose threats to global food security. Utilizing satellite data and GBIF observations, we find climate‐induced shifts in habitats and expansion patterns, notably the elevation increase of Striga asiatica ...

Are root parasitic broomrapes still a good target for bioherbicide control?

Pest Management Science, Volume 80, Issue 1, Page 10-18, January 2024.
Root parasitic weeds of the genera Orobanche and Phelipanche (commonly named broomrapes), responsible for enormous yield losses of several crops all around the world, are hardly manageable because of their physiological and biological properties. Although there are no commercial products and effective applications, microbiological control has enormous ...
