Technical Abstract: Aluminum (Al) toxicity is one of the most significant limitations to crop production worldwide, reducing yields on the acidic soils that comprise up to 50% of potentially arable lands. Breeding for Al tolerance and agronomic practices aimed at ameliorating soil acidity have been productive avenues for improved crop production on acid soils. However, it is widely recognized that biotechnology is a very important avenue for further future improvements in Al tolerance, especially for farmers without the economic resources to take advantage of improved agronomic practices. Hence a number of the laboratories around the world are working to identify and characterize Al tolerance genes in plants. The Kochian lab has been taking an interdisciplinary approach integrating approaches from genetics, genomics and molecular biology, and physiology to identify Al tolerance genes and the associated mechanisms in 3 model plant systems: sorghum, maize and Arabidopsis thaliana.
