The genetic basis of plants’ battle against witchweeds: linking immune responses to distinct resistance mechanisms

Jhu MY, Kawa D, Brady SM - Journal of experimental botany, 2023


Parasitic plants of the Striga species significantly damage cereals in sub-Saharan Africa. Current agricultural practices are insufficient to manage Striga infestation, necessitating sustainable approaches that harness natural resistance mechanisms. Mutinda et al. (2023) examined how different genotypes of sorghum plants resist Striga after it attacks their roots. By comparing transcriptomes, they found that sorghum activates its immune system, and molecular signatures probably associate with distinct resistance mechanisms. This study will inform the development of Striga-resistant sorghum varieties to ward off root parasitic plants.
