A potential role of heat-moisture couplings in the range expansion of Striga asiatica. [PDF]

Ecol Evol
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 ...

Induction of systemic resistance to Orobanche crenata in lentil by exogenous application of salicylic acid and indole acetic acid [PDF]

Journal of Plant Protection Research, 2023
Orobanche crenata parasitism on lentil ( Lens culinaris Medik) is one of the most destructive factors for this crop in Morocco. Field and pot assays were performed to study the mitigation of O.

Resistance to Orobanche crenata Forsk. in lentil (Lens culinaris Medik.): exploring some potential altered physiological and biochemical defense mechanisms

Journal of Plant Interactions, 2021
Management of broomrape (Orobanche crenata Fosk.) that causes important damages on lentil production becomes a veritable concern in the Mediterranean region. Eighty lentil accessions were evaluated for resistance to O.

Host‐associated genetic differentiation and origin of a recent host shift in the generalist parasitic weed Phelipanche ramosa

Ecology and Evolution, Volume 13, Issue 9, September 2023., 2023
Branched broomrape, Phelipanche ramosa, is a parasitic weed that can infest several crops, notably tobacco, hemp, and tomato. In western France, it has recently adapted to a new host, oilseed rape. We describe the genetic diversity of populations sampled from six different crops across Europe.

Detection of genetic variations in orobanche crenata using inter simple sequence repeat (ISSR) markers

Bulletin of the National Research Centre, 2020
Background This recent investigation aimed to detect and characterize the genetic variabilities and genetic similarity in Orobanche crenata collected from naturally Orobanche-infested field at Gemmeiza Research Station, Agriculture Research Center (ARC),

Assessment of weed root extracts for allelopathic activity against Orobanche and Phelipanche species

Phytopathologia Mediterranea, 2021
Broomrapes (Orobanche and Phelipanche species) are holoparasitic weeds that infect roots of crop hosts from Asteraceae, Brassicaceae, Apiaceae, Fabaceae, and Solanaceae.

Evaluation of the phytotoxic and antifungal activity of C17‐sesquiterpenoids as potential biopesticides

Pest Management Science, Volume 78, Issue 10, Page 4240-4251, October 2022., 2022
C17‐sesquiterpenoids exhibited strong phytotoxic and antifungal activity. The lack of the α‐methylene‐γ‐butyrolactone system in their structure did not extinguish their bioactivities. Abstract BACKGROUND Natural products are a promising source for the development of new pesticides with alternative mechanisms of action.

(±)-Catechins inhibit prehaustorium formation in the parasitic weed Phelipanche ramosa and reduce tomato infestation. [PDF]

Pest Manag Sci
Cytokinins (CKs) induce papillae (prehaustorium) formation (A, red arrow). (±)‐Catechins application prevent CK‐induced prehaustorium formation without affecting radicle growth (B). Soil application of (±)‐catechins is effective in lowering parasite attachment to tomato plants. Abstract BACKGROUND Phelipanche ramosa L.

Genetic Structure and Diversity Analysis of Tunisian Orobanche spp. and Phelipanche spp. Using Molecular Markers

Applied Sciences, 2023
Broomrapes (Orobanche and Phelipanche spp.) are non-achlorophyllous parasitic plants belonging to the Orobanchaceae family, with some species evolving to infest agricultural crops, causing substantial economic losses.

Sphaeropsidin A: A Pimarane Diterpene with Interesting Biological Activities and Promising Practical Applications

ChemBioChem, Volume 22, Issue 23, Page 3263-3269, December 2, 2021., 2021
The fungal pimarane diterpene sphaeropsidin A (SphA) has shown promising application in agriculture and medicine. This article reviews its biosynthetic origins, fungal sources, preparation of semisynthetic derivatives and biological activities as well as the results of structure‐activity relationship (SAR) studies.
