Abstract

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.
