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).

Discovery of strigol synthase from cotton (Gossypium hirsutum): The enzyme behind the first identified germination stimulant for Striga

PLANTS, PEOPLE, PLANET, Volume 7, Issue 2, Page 354-359, March 2025.
Parasitic witchweeds (Striga species) pose a serious threat to food security in Africa, attacking cereal grains and legumes. Chemicals released from the host roots that initiate the life cycle of Striga are known as germination stimulants, predominantly strigolactones (SLs).

Aging seeds of weedy broomrapes and witchweeds lose sensitivity to strigolactones as DNA demethylates

PLANTS, PEOPLE, PLANET, Volume 7, Issue 2, Page 476-485, March 2025.
Broomrapes and witchweeds have devastating effects on crops in parts of Europe, Africa, and Asia. The key to their success is the production of copious, long‐lived seeds, which germinate in response to the perception of chemicals released by their hosts' roots.

Opportunities for expansion of push-pull technology as an agroecological and sustainable intensification approach in Africa

npj Sustainable Agriculture
The push-pull technology (PPT) has often been presented as a management strategy for stemborers and witchweed. However, its value as an agronomic practice and an agroecological approach remains largely underappreciated.
