This work evaluated aluminium resistance in genotypes of Brachiaria brizantha cv. MG4, transformed with the neMDH gene, by using a nutrient solution for agronomic evaluation and gene integration confirmation by PCR. Three from the five confirmed transformed genotypes of B. brizantha cv. MG4 with the neMDH gene presented tolerance to aluminium solutions (111 µmol L -1 and 444 µmol L -1). Two from those three genotypes also showed higher dry weight production in comparison to the wild-type genotype. Keywords: Brachiaria, Tolerance, Aluminum, Soil, Transgenic, neMDH.
