Transcriptome atlas of Striga germination: Implications for managing an intractable parasitic plant

Plants, People, Planet
Societal Impact Statement Witchweeds, parasitic plants of the genus Striga, are nicknamed “cereal killers” because of their devastating destruction of Africa's most staple cereals, including maize, sorghum, millets, and upland rice.

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

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.

Strigolactone biosynthesis lgs1 mutant alleles mined from the sorghum accession panel are a promising resource of resistance to witchweed (Striga) parasitism

Plants, People, Planet
Societal Impact Statement Striga is a parasitic plant that greatly limits the production of Africa's most staple cereals, including sorghum. Infection occurs when the parasite germinates in response to biomolecules emitted into the soil from the host's ...

Has the Striga problem been solved? A field perspective critique of recent progress. [PDF]

Pest Manag Sci
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 powerful molecular marker to detect mutations at sorghum LOW GERMINATION STIMULANT 1. [PDF]

Plant Genome
Abstract The parasitic weed Striga (Striga hermonthica) limits productivity of sorghum (Sorghum bicolor) and other cereals in sub‐Saharan Africa and elsewhere. Improved host plant genetics is an effective control method but verified loci contributing to Striga resistance are limited.
