Differences in the ecology of witchweed and vampireweed: Implications for rice farming in Africa [PDF]

Plants People Planet
Societal Impact Statement Parasitic weeds in African rice systems threaten household‐level food security and income generation. Most affected farmers are smallholders with limited capacities to address these pests.

Maize resistance to witchweed through changes in strigolactone biosynthesis [PDF]

Science, 2023
Maize ( Zea mays ) is a major staple crop in Africa, where its yield and the livelihood of millions are compromised by the parasitic witchweed Striga .

Witchweed’s Suicidal Germination: Can Slenderleaf Help? [PDF]

Agronomy, 2020
The parasitic plant Striga hermonthica (Delile) Benth. is stimulated to germinate by biomolecules (strigolactones) produced in the roots of host and some non-host plants. Non-hosts induce Striga’s suicidal germination and are therefore used as trap crops. Among trap crops, the Slenderleaf legume in the genus Crotalaria (Crotalaria brevidens (L.) Benth.)

The witchweed Striga gesnerioides and the cultivated cowpea: A geographical and historical analysis of their West African distribution points to the prevalence of agro-ecological factors and the parasite’s multilocal evolution potential

PLoS ONE, 2021
The increasing severity of Striga gesnerioides attacks on cowpea across West Africa has been related to its prolificity, seed mobility and longevity, and adaptation to aridity, in a context of agricultural intensification.

Striga hermonthica: A highly destructive pathogen in maize production

Environmental Challenges, 2022
Maize is a major cereal crop in sub-Saharan Africa (SSA). Subsistence farmers mostly plant it in areas where the parasite Striga hermonthica's action often reduces the harvest.

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.

GWAS provides biological insights into mechanisms of the parasitic plant (Striga) resistance in sorghum

BMC Plant Biology, 2021
Background Sorghum yields in sub-Saharan Africa (SSA) are greatly reduced by parasitic plants of the genus Striga (witchweed). Vast global sorghum genetic diversity collections, as well as the availability of modern sequencing technologies, can be ...
