, 2020 Host-specific interactions can maintain genetic and phenotypic diversity in parasites that attack multiple host species. Host diversity, in turn, may promote parasite diversity by selection for genetic divergence or plastic responses to host type.

IATITCHWEED (Striga asiatica) was first collected and identified in V Vthe United States during the late summer of 1956. This parasite attacks the roots of plants primarily in the family Gramineae. In the United States it appears to be a potential threat to the corn and grain sorghum crops.

Dihydroparthenolide and other sesquiterpene lactones stimulate witchweed germination
Phytochemistry, 1989Abstract Four sesquiterpene lactones which share structural features of the lactone rings of strigol were tested as witchweed germination stimulants. Confertiflorin and parthenin significantly increased witchweed germination at 10 −4 M, and parthenin and desacetylconfertiflorin increased germination at 10 −5 M.

Canadian Journal of Plant Science, 2020 Witchweed [Striga hermonthica (Del.) Benth] is a major parasitic weed of most cereal crops in Africa, including maize. Seed treatment with low doses of acetolactate synthase–inhibiting herbicides, such as imazapyr, was introduced in the 1990s to control ...

Conferring resistance to parasitic witchweed by shifting strigolactone biosynthesis
Trends in Parasitology, 2023Strigolactones from the exudates of maize root induce germination of the parasitic witchweed Striga. Recently, Li et al. characterized the biosynthesis pathway of two strigolactones, zealactol and zealactonoic acid, which induce less Striga germination than the major maize strigolactone, zealactone.
