This invention relates to a major aluminum tolerance gene, SbMATE (for Sorghum bicolor ember of the multidrug and toxic compound extrusion transporter family), that is responsible for AltSB locus (for aluminum tolerance in Sorghum bicolor), cloned from sorghum along with its native promoter and regulatory regions, a construct containing a gene and a constitutive promoter, a vector containing the construct, and a method of transforming a plant utilizing the construct and vector, and plants, including staple crop plans, transformed with the gene construct having increased tolerance to aluminum toxicity.
Sorghum bicolor major aluminum tolerance (SbMATE) gene
• Isolated from sorghum
• Enables plants to grow normally in aluminum‐ rich soil, which is normally toxic to crops
– aluminum toxicity is one of the primary limitations for crop production in developing countries
– crops such as wheat, rice, and maize are unable to grow in aluminum‐rich soil because aluminum in such soil takes a chemical form that is toxic to them
