Role of Rhizosphere Microbial Communities in Enhancing Stress Tolerance of Sorghum under Changing Climatic Conditions
Author(s): Samuel Otieno
Abstract: Sorghum (Sorghum bicolor L. Moench) is a critical cereal for food security in semi-arid landscapes. Its resilience under drought, heat, and nutrient-poor conditions is increasingly threatened by climate change. Emerging research highlights the central role of rhizosphere microbial communities in enhancing stress tolerance through nutrient mobilization, phytohormone regulation, and improved root-soil interactions. This paper synthesizes evidence from global semi-arid zones—Sub-Saharan Africa, the Brazilian Cerrado, and the Indo-Gangetic drylands—combining experimental findings with global production data from FAOSTAT and USDA-FAS. We analyze microbial consortia such as plant growth-promoting rhizobacteria (PGPR), arbuscular mycorrhizal fungi (AMF), and endophytes that facilitate sorghum adaptation. The findings suggest microbial inoculants and microbiome engineering hold promise for climate-smart sorghum production, particularly in rainfed systems.
