Identification of dominant mutations that confer increased aluminium tolerance through mutagenesis of the Al-sensitive Arabidopsis mutant, als3-1.

Abstract excerpt

Aluminium (Al) toxicity is a global agricultural problem that occurs in acid soil environments and severely limits root growth and crop productivity. The isolation and characterization of a gene, ALS3, which is absolutely required by Arabidopsis seedlings for growth in an Al-toxic environment was reported previously. Since the als3-1 loss-of-function mutant has extreme root growth inhibition even in the presence...
