Reactive Oxygen Species (ROS) Generation Is Indispensable for Haustorium Formation of the Root Parasitic Plant Striga hermonthica

Frontiers in Plant Science, 2019
The parasitic witchweed Striga hermonthica causes devastating damage to crops in sub-Saharan Africa, yet the mechanism of its parasitism is not well understood.

Methodology for Establishing Witchweed (Striga asiatica) in Research Plots

, 1990
Experiments were conducted in North Carolina and South Carolina, 1989, to evaluate methods of infesting research plots with witchweed. At both locations sowing witchweed (mixed with very fine sand) in or beneath the maize planting hole resulted in more ...

Strigolactones and sesquiterpene lactones induce Orobanche cumana germination via KAI2d receptors through distinct processes

The Plant Journal, Volume 126, Issue 1, April 2026.
SUMMARY Orobanche cumana is an obligate parasitic weed belonging to the Orobanchaceae family and represents the most important biotic constraint to sunflower seed production in all the regions where sunflower is cultivated, except in North and South America. O.

Striga (Witchweed) Threats to Cereal Crops Production and Its Management: A Review [PDF]

, 2021
Striga (witchweed) is one of the most successful parasitic weeds of cereal crops in Africa. It is ‘a poor farmer’s problem’ as there is a near perfect ecological overlap between areas of Striga infestation and where hunger prevails.

Global changes in gene expression during compatible and incompatible interactions of cowpea (Vigna unguiculata L.) with the root parasitic angiosperm Striga gesnerioides

BMC Genomics, 2012
Background Cowpea, Vigna unguiculata L. Walp., is one of the most important food and forage legumes in the semi-arid tropics. While most domesticated forms of cowpea are susceptible to the root parasitic weed Striga gesnerioides, several cultivars have ...

In Vitro and In Vivo Evaluation of Sorghum (Sorghum bicolor L. Moench) Genotypes for Pre- and Post-attachment Resistance against Witchweed (Striga asiatica L. Kuntze)

International Journal of Agronomy, 2020
Sorghum (Sorghum bicolor L. Moench) production in sub-Saharan Africa is seriously constrained by both biotic and abiotic stresses. Among the biotic stresses is witchweed (Striga spp.), a noxious parasitic weed causing major damage in cereal crops, such ...

Parasitic Plant–Host Interactions: Molecular Mechanisms and Agricultural Resistance Strategies

Advanced Science, Volume 13, Issue 16, 18 March 2026.
Parasitic plants devastate global agriculture through sophisticated molecular interactions with host crops. This review synthesizes current understanding of parasitic plant‐host interactions, from strigolactone‐mediated germination and haustorium formation to host defense mechanisms.

Has the Striga problem been solved? A field perspective critique of recent progress

Pest Management Science, Volume 82, Issue 1, Page 54-59, January 2026.
The potential field efficacy of recently proposed breeding, biocontrol, suicidal germination, gene editing and transgenic solutions for Striga control is critically evaluated and mostly found wanting improvements. Abstract Three root‐parasitic witchweed (Striga) species can cause up to total loss of grain and legume crops for millions of farmers in ...

A full-length enriched cDNA library and expressed sequence tag analysis of the parasitic weed, Striga hermonthica

BMC Plant Biology, 2010
Background The obligate parasitic plant witchweed (Striga hermonthica) infects major cereal crops such as sorghum, maize, and millet, and is the most devastating weed pest in Africa.
