Phenolic signals for prehaustorium formation in Striga hermonthica. [PDF]

Front Plant Sci, 2022
Striga hermonthica is a root parasitic plant that causes considerable crop yield losses. To parasitize host plants, parasitic plants develop a specialized organ called the haustorium that functions in host invasion and nutrient absorption. The initiation of a prehaustorium, the primitive haustorium structure before host invasion, requires the ...

Rational design of Striga hermonthica-specific seed germination inhibitors. [PDF]

Plant Physiol, 2022
AbstractThe obligate hemiparasitic weed Striga hermonthica grows on cereal roots and presents a severe threat to global food security by causing enormous yield losses, particularly in sub-Saharan Africa. The rapidly increasing Striga seed bank in infested soils provides a major obstacle in controlling this weed.

Association analysis for resistance to Striga hermonthica in diverse tropical maize inbred lines [PDF]

Scientific Reports, 2021
Striga hermonthica is a widespread, destructive parasitic plant that causes substantial yield loss to maize productivity in sub-Saharan Africa. Under severe Striga infestation, yield losses can range from 60 to 100% resulting in abandonment of farmers ...

Diacetoxyscirpenol, a Fusarium exometabolite, prevents efficiently the incidence of the parasitic weed Striga hermonthica [PDF]

BMC Plant Biology, 2022
Background Certain Fusarium exometabolites have been reported to inhibit seed germination of the cereal-parasitizing witchweed, Striga hermonthica, in vitro. However, it is unknown if these exometabolites will consistently prevent S.

How does Striga hermonthica Bewitch its hosts? [PDF]

Plant Signal Behav, 2019
The common name witchweed synonymous with the Latin name Striga befits the bewitching effects, viz wilting and chlorosis, the parasite inflicts on its hosts long before it emerges and becomes visible above the ground. However, interactions in the rhizosphere between host roots and Striga seedlings are concealed and inscrutable.

Characterization of host tolerance to Striga hermonthica [PDF]

Euphytica, 2006
One of the most promising control options against the parasitic weed Striga hermonthica is the use of crop varieties that combine resistance with high levels of tolerance. The aim of this study was to clarify the relation between Striga infestation level,

Striga parasitizes transgenic hairy roots of Zea mays and provides a tool for studying plant-plant interactions [PDF]

Plant Methods, 2012
Background Striga species are noxious root hemi-parasitic weeds that debilitate cereal production in sub-Saharan Africa (SSA). Control options for Striga are limited and developing Striga resistant crop germplasm is regarded as the best and most ...
