Pearl millet genomic vulnerability to climate change in West Africa highlights the need for regional collaboration

B. Rhoné, D. Defrance, et al.

This groundbreaking research delves into the genomic vulnerability of pearl millet as climate change jeopardizes food security in sub-Saharan Africa. The study reveals critical vulnerabilities at northern cultivation edges and suggests that seed exchange among landraces could play a significant role in combatting these challenges. Conducted by Bénédicte Rhoné and colleagues, the findings emphasize the importance of regional collaboration.

Abstract
Climate change is impacting agro-ecosystems and threatening food security. This study investigates the genomic vulnerability of pearl millet, a staple cereal in sub-Saharan Africa, to climate change. Analyzing genomic diversity of 173 landraces and climate data, the northern cultivation edges of both early and late flowering varieties are identified as most vulnerable. The study predicts that landraces from similar current climates could mitigate this, but regional collaboration is needed for seed exchange.
