Introgression of a 4D chromosomal fragment into durum wheat confers aluminium tolerance

Aluminium (Al(3+)) inhibits root growth of sensitive plant species and is a key factor that limits durum wheat (Triticum turgidum) production on acid soils. The aim of this study was to enhance the Al(3+) tolerance of an elite durum cultivar by introgression of a chromosomal fragment from hexaploid wheat (Triticum aestivum) that possesses an Al(3+) tolerance gene.
