This project will utilize our genetic resources already available including near isogenic maize lines for both QTLs, as well as segregating populations and crosses between Brazilian sources of Al tolerance and Kenyan adapted germplasm. This structured germplasm, as well as newly developed crosses, will be subjected to molecular, physiological and field evaluations in order to accomplish the functional validation of candidate genes or QTLs, henceforth referred to as ZmMATE, for improving Al tolerance in different tropical maize germplasm. This project within the Comparative Genomics Challenge Initiative will involve Embrapa, USDA / Cornell University, Moi University and KARI, a research group with a long term history of successful partnership. The research findings from this project will both greatly increase our understanding of the molecular and genetic basis for cereal Al tolerance, and more importantly, will provide the basic materials for molecular breeding programs focusing on improving maize production and stability on acid soils in Africa and other developing country regions.
