Challenges to the exploitation of host plant resistance for Striga management in cereals and legumes by farmers in sub-Saharan Africa: a review

Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2019
Striga hermonthica, Striga asiatica and Striga gesneroides are obligate root parasites that cause severe yield losses in cereals and legumes in sub-Saharan Africa. Genetic control of Striga through resistance is widely considered to be the most practical

Cloning and characterisation of a maize carotenoid cleavage dioxygenase (ZmCCD1) and its involvement in the biosynthesis of apocarotenoids with various roles in mutualistic and parasitic interactions [PDF]

, 2008
Colonisation of maize roots by arbuscular mycorrhizal (AM) fungi leads to the accumulation of apocarotenoids (cyclohexenone and mycorradicin derivatives).

Host-Parasite Interactions Throughout the Striga Life Cycle, and their Contributions to Striga Resistance

African Crop Science Journal, 2011
Field screening for resistance to Striga has been slow and difficult, with only modest success. Successful Striga parasitism is dependent upon a series of chemical signals produced by its host. Interruption of one or more of these signals results in failure to establish parasitism.

Identification of resistant genotypes against Striga asiatica (L.) Kuntze in kodo millet

Electronic Journal of Plant Breeding, 2018
Performance of 25 pre-release cultures and 13 released varieties of kodo millet were assessed for Striga resistance under artificial inoculation. Significant variation in Striga related parameters were recorded among the evaluated genotypes.

Efficacy of maize inbred testers with varying levels of resistance to Striga for classifying Striga-resistant yellow-maize lines into heterotic groups

Journal of Crop Improvement, 2021
L'identification de testeurs efficaces pour séparer les lignées consanguines de maïs (Zea mays L.) en groupes hétérotiques peut faciliter le développement d'hybrides supérieurs. Les lignées consanguines de maïs jaune résistantes aux striga développées à l'Institut international d'agriculture tropicale (IITA) n'ont pas de groupes hétérotiques bien ...
